+# TITLE:  Establishing ADRs for US Notify
+
+
+| CREATED DATE | LAST UPDATED | STATUS | AUTHOR | STAKEHOLDERS |
+| :---: | :---: | :---: | :---: | :---: |
+| 06/01/2023 | 06/15/2023 | Accepted | @ccostino | @stvnrlly |
+
+
+## CONTEXT AND PROBLEM STATEMENT
+
+**OPEN ISSUE:** https://github.com/GSA/notifications-api/issues/282
+
+As a developer of the system, I'd like to be able to keep track of system
+architecture decisions and understand why they were made, including what
+trade-offs and alternatives might have existed at the time. I'd also like to
+keep track of these in a place that I can refer back to later for historical
+context.
+
+
+## DECISION DRIVERS
+
+These are the key considerations for creating ADRs for US Notify:
+
+- We'd like to establish a decision-making framework for future proposals to
+  improve or change the product/service.
+
+- We'd like to document the outcome of our decisions and include the rationale
+  behind them to know what we've already considered previously.
+
+- In the spirit of open source and collaboration, we'd like to make our
+  decisions as open as possible, but recognize there are times when we cannot;
+  in those cases, we'll follow the same process but in a private location.
+
+- We need to make sure we're accounting for any security compliance concerns
+  and considerations ahead of time, while we're actively thinking about how to
+  architect and implement a thing instead of after the fact.
+
+
+### SECURITY COMPLIANCE CONSIDERATIONS
+
+- Documenting architectural details in the open
+  - We should err on the side of documenting in the open whenever possible, but
+    some details we will not be able to share.  We should create issues for
+    those cases to note the work happening in a private space.
+
+- Sensitive information must not be shared
+  - We need to be judicious in not documenting any sensitive bits of information
+    like account credentials or passwords, environment variable values, etc.
+
+
+## CONSIDERED OPTIONS
+
+- **Architectural Decision Records:**  A common document format for capturing
+  architectural decisions that many development teams have adopted in recent
+  years, including at large technology companies such as
+  [GitHub](https://adr.github.io/) and [Amazon Web Services](https://docs.aws.amazon.com/prescriptive-guidance/latest/architectural-decision-records/welcome.html) and TTS' own [18F](https://18f.gsa.gov/2021/07/06/architecture_decision_records_helpful_now_invaluable_later/).
+
+  - Pros:
+    - Well-known format that has many example templates to choose from
+    - Can be as simple or complex as desired
+    - Additional tooling exists to help manage ADRs
+    - ADRs are committed to and live with the code itself
+    - Easy to link to other parts of the repo
+
+  - Cons:
+    - Takes a bit of prep to setup; best supported with a template to copy from
+    - Setting up additional tooling takes time and requires additional
+      maintenance
+    - Requires some training for folks not already familiar with ADRs
+    - Easy to go overboard with
+    - Requires being mindful of what can live in the public space vs. not
+
+- **Google Docs in Google Drive:**  Writing up notes docs in Google Drive with
+  Google Docs.
+
+  - Pros:
+    - Simple and lightweight to do
+    - Possible to setup a doc template to create from, if desired
+    - Ability for team members to collaborate in real-time with each other
+    - Useful for documenting things that cannot be public
+    - Access to tools/features like a spellchecker
+
+  - Cons:
+    - Google Drive organization is difficult; keeping track of documents
+      can become hard
+    - Easy to not follow a standard and agreed upon format
+    - Not open to the public for things that can be shared publicly
+    - Documentation does not live directly with the code
+
+- **GitHub Issues and/or Wiki:**  Writing up notes and decisions directly in
+  GitHub issues and/or the wiki associated with a repo.
+
+  - Pros:
+    - Simple and lightweight to do
+    - Possible to configure an issue template to create from, if desired
+    - Easy to link to related issues, wiki pages, etc.
+
+  - Cons:
+    - Documentation lives in a GitHub itself, not the code repository directly;
+      therefore, it's not portable
+    - Easy to not follow a standard and agreed upon format if no template is
+      provided
+    - Requires being mindful of what can live in the public space vs. not
+
+
+## CHOSEN OPTION:  Architectural Decision Records
+
+Our team has chosen to adopt Architectural Decision Records going forward for
+any decisions that need to be proposed or discussed that will have a significant
+impact on the platform.
+
+By documenting our changes in this fashion, it will improve our team's
+development practices and software quality in a few ways:
+
+- Encourage us to slow down and think through a new change, especially anything
+  of significance
+- Hold us accountable to each other in soliciting feedback for our work and
+  engaging in discussions earlier in the process of building something
+- Provide a mechanism to propose ideas for changes and improvements to the
+  system that is also archived with the code itself
+- Bake security compliance considerations into our development process from the
+  start, ensuring they are not just after-thoughts once something is completed
+
+ADRs have a wealth of material and support to draw from, other teams across TTS
+are already using them (e.g., cloud.gov, a variety of 18F projects, and others),
+and other large organizations, including GitHub and Amazon, have also adopted
+them.  Some example material to reference:
+
+- [How to Create ADRs - and How Not To](https://www.ozimmer.ch/practices/2023/04/03/ADRCreation.html)
+- [The Markdown ADR (MADR) Template Explained and Distilled](https://www.ozimmer.ch/practices/2022/11/22/MADRTemplatePrimer.html)
+- [The Ultimate Guide to Architectural Decision Records](https://betterprogramming.pub/the-ultimate-guide-to-architectural-decision-records-6d74fd3850ee)
+
+
+### Consequences
+
+- Positive
+  - Formal decision documentation and history
+  - Proactive security compliance considerations in the decision-making process
+  - Accepted means of proposing new ideas for the future
+
+- Negative
+  - A bit of a learning curve in making sure all team members are aware and
+    brought up to speed of what ADRs are
+  - Some configuration and set up required; mainly new templates, though one is
+    provided with this proposal
+
+
+## VALIDATION AND NEXT STEPS
+
+@stvnrlly and I went over this proposal and have worked together to get it in
+the shape it needs to be for the team to work off of.  The corresponding ADR
+README.md that was a part of the original pull request was also refined to make
+sure it contains all relevant information and instructions.

+# TITLE:  Determine How to Handle Timezones in US Notify
+
+
+| CREATED DATE | LAST UPDATED | STATUS | AUTHOR | STAKEHOLDERS |
+| :---: | :---: | :---: | :---: | :---: |
+| 06/06/2023 | 06/15/2023 | Accepted | @terrazoon, @ccostino | @GSA/notify-contributors |
+
+
+## CONTEXT AND PROBLEM STATEMENT
+
+**OPEN ISSUE(S):** https://github.com/GSA/notifications-api/issues/260, along
+with a related pull request: https://github.com/GSA/notifications-api/pull/272
+
+Currently, the application converts back and forth to Eastern Time in a few
+places, using utilities provided by `notifications-utils`. This adds complexity
+and possible confusion since we'll actually be working over multiple timezones.
+
+We are currently linked to timezones in the backend, and we want to unlink it,
+but we quickly find places where things do not match up.
+
+
+## DECISION DRIVERS
+
+We're looking for these primary outcomes with this work:
+
+- Find all the time-dependent pieces of the application.
+- Decide what we can tackle now versus later.
+- Determine what the return on this is.
+
+We've also identified the following areas as pieces of the application and
+service that could be impacted by any timezone changes:
+
+- Reports by day (or specific month/year)
+- Jobs running at a reasonable time 
+- Job schedules (we want users to understand when things will happen)
+- Scheduling sending of messages
+- UI listing of time messages were sent
+
+Ultimately, we're looking for the least disruption possible while maximimizing
+our ability to operate the service consistently with predictable results.
+
+
+### SECURITY COMPLIANCE CONSIDERATIONS
+
+None at this time, given that the nature of this work is strictly changing the
+way timezones are handled in the existing application.
+
+
+## CONSIDERED OPTIONS
+
+As a team, we've gone through the following options:
+
+- **Backend UTC, frontend explicitly ET**:  We convert the backend to UTC and
+  keep the frontend as Eastern Time.
+
+- **Backend UTC, frontend UTC**:  We convert both the backend and frontend to
+  UTC time.
+
+- **Backend UTC, frontend configurable at service level**:  We convert the
+  backend to UTC and make the frontend configurable at the eservice level.
+
+- **Backend UTC, frontend configurable at user level**:  We convert the backend
+  to UTC and make the frontend configurable at the user level.
+
+- **Backend UTC, frontend verbose (various options)**:  We convert the backend
+  to UTC and strive for maximum flexibility on the frontend with a variety of
+  configuration options.
+
+For all of these options, we've settled on the need to adjust the backend
+service to operate and manage timezones with UTC only.
+
+Pros of converting the backend to UTC:
+
+- Eliminates entire classes of bugs trying to synchronize jobs, reports,
+  scheduling of sending messages, etc., and ensures things are always running
+  when expected.
+
+- This is a fairly standard industry practice when dealing with any timezone
+  management in the applicationo; have the backend operate strictly with UTC
+  and leave the display and formatting of timezones in local time to the client.
+
+Cons of converting the backend to UTC:
+
+- There's a decent amount of work involved in the conversation, and tests need
+  to be updated to ensure they're accounting for the timezone change as well.
+
+For the frontend choices we have, it comes down to level of effort, time
+involved, and what is a higher priority for us now versus later.
+
+Pros of converting parts of the frontend now:
+
+- It provides a bit of consistency with the backend change, and accounts for the
+  work now instead of later.
+
+- It offers a level of configuration not currently available in the app, which
+  would allow users to interact with and customize it in ways that better suite
+  their needs and preferences.
+
+Cons of converting parts of the frontend now:
+
+- There is a lot of additional work involved, not all touch points are known,
+  and there is a signficant effort underway at the moment to update the
+  frontend design and information architecture.
+
+- We're still not entirely sure at which level of granularity we'd like to offer
+  customization, if any.
+
+
+## CHOSEN OPTION:  Backend UTC, frontend UTC
+
+After talking through each of these options together as a team, we have decided
+to move forward with converting the backend to UTC fully and pairing that work
+with displaying UTC in the frontend where need be.
+
+@terrazoon had an [open PR](https://github.com/GSA/notifications-api/pull/272)
+with most of the work already accounted for, and explained the rationale for
+making the change based on previous work and project experience.
+
+Multiple team members also spoke about the benefits of storing, processing, and
+managaging timezones as only UTC in the backend of the system and that it's
+worth the additional work to implement.  The challenges inherent in trying to
+manage timezones directly are too many and greatly increase the risk of new bugs
+and undesired behavior and side-effects being introduced into the system.
+
+
+### Consequences
+
+- Positive
+  - Work was already partially complete for the backend adjustment.
+  - Consistent handling of timezones with just UTC across the system in the
+    backend.
+  - Provides support to adjust the frontend and other clients as desired going
+    forward.
+
+- Negative
+  - The additional work includes updating tests to make sure they all continue
+    to work properly.
+  - User testing will also have to be conducted to account for both the app
+    still functioning properly and noting where in the UI/frontend things will
+    need to change.
+
+
+## VALIDATION AND NEXT STEPS
+
+With the decision to move the backend to UTC, the following actions need to be
+taken:
+
+- **Change the backend to use UTC:**  Remove all references to specific
+  timezones and switch everything to use UTC.
+  - Accounted for in https://github.com/GSA/notifications-api/pull/272
+
+- **Update tests to account for the UTC change:**  All of the tests that have
+  anything to do with a timezone will need to be updated to continue to work
+  properly.
+  - Accounted for in https://github.com/GSA/notifications-api/pull/272
+
+We also need to update the frontend to account for these changes.  This will be
+done in two parts:
+
+1. We'll update the UI to make sure everything reflects UTC where necessary for
+   any timzone displays.  This work will be tracked in this issue:
+   https://github.com/GSA/notifications-admin/issues/525
+
+1. We need to create an ADR for future frontend work for how we'd like to handle
+   timezones in the UI going forward.  This is currently noted in this issue:
+   https://github.com/GSA/notifications-api/issues/286

+# TITLE:  Implementing User Invite Expirations
+
+
+| CREATED DATE | LAST UPDATED | STATUS | AUTHOR | STAKEHOLDERS |
+| :---: | :---: | :---: | :---: | :---: |
+| 06/06/2023 | 06/15/2023 | Proposed | @ccostino | @GSA/notify-contributors |
+
+
+## CONTEXT AND PROBLEM STATEMENT
+
+**OPEN ISSUE(S):** https://github.com/GSA/notifications-admin/issues/96
+
+We've run into a situation where we want to re-invite users when their previous
+invites have expired.  However, we're not currently able to do that because
+there is no mechanism in the app (specifically the API and the data model) to
+support expired invites.
+
+Right now, users who are invited to the system receive an email invitation that
+includes a note that the invitation will expire after 24 hours.
+
+However, on the backend side of things, no such expiration exists.  Instead,
+there is a scheduled job that runs every 66 minutes to check for all
+`InvitedUser` objects that are older than 2 days and deletes them.
+
+([Issue #96 in `notifications-admin`](https://github.com/GSA/notifications-admin/issues/96)
+has more specific details.)
+
+
+## DECISION DRIVERS
+
+We'd like to adjust the API and data model so that invited users are no longer
+deleted from the system and are instead tracked as active or expired.  When an
+invite is expired, we'd like to be able to re-invite the person.
+
+
+### SECURITY COMPLIANCE CONSIDERATIONS
+
+The system currently has a data model for capturing an invited user
+(`InvitedUser`), which is based on an authorized user of the system having the
+permission to invite others to it.
+
+These changes should not deviate from the existing structures and contraints
+that are already in place, which prevent the following:
+
+- Unauthorized users from accessing the system
+- Users without the proper permissions from inviting others
+
+
+## CONSIDERED OPTIONS
+
+These are the different approaches we're considering for implementing this
+change:
+
+- **Adjust `InvitedUser` management in the API:**  Instead of deleting
+  `InvitedUser` objects, we manage them instead and track their `created_at`
+  dates for when they need to expire.  This would involve the following
+  potential changes:
+
+  - Add an `expired` flag to the `InvitedUser` model
+
+  - Change the `delete_invitations` scheduled job to `expire_invitations` and
+    change its behavior to check for `InvitedUser` objects that are older than
+    24 hours and flip the `expired` flag to `True`.
+
+  - Add an additional `INVITE_EXPIRED` status to the API and include it in the
+    `INVITED_USER_STATUS_TYPES` enum.  This will be necessary for future UI
+    changes.
+
+  - Make sure the API responses that provided `InvitedUser` objects/data
+    included the new `expired` field and status.
+
+  - Update all tests related to `InvitedUsers` to account for the new behavior.
+
+  The pros in making this change:
+
+  - This will enable us to support expiring invites in the system, including
+    frontend changes to enable seeing and managing expired invites.
+
+  The cons in making this change:
+
+  - Updated the tests might be a bit challenging depending on how many there are
+    (especially any related to scheduled jobs).
+
+
+## PROPOSED OPTION:  Adjust `InvitedUser` management in the API
+
+I am proposing we adjust the `InvitedUser` management in the API and get these
+updates in place first for future UI changes, because without them we cannot
+display any expired invites nor offer a way of managing them or providing an
+option to re-invite folks.
+
+After looking through the code and researching how the existing user invite
+flow works, these changes seem straight-forward and would yield us a lot of
+value for the effort.
+
+
+### Consequences
+
+- Positive
+  - Allows us to support expired invites
+  - We could allow for custom expiration periods (either now or in the future)
+  - Provides the mechanisms needed in the frontend to display and manage
+    expired invites
+
+- Negative
+  - We might end up having to adjust a lot of tests; that's currently unclear.
+
+
+## VALIDATION AND NEXT STEPS
+
+TBD, pending additional ideas and discussion!
+
+Once a decision is made though, a seperate issue should be written up for the
+API changes that need to take place, and then follow-on work will be needed on
+the admin side in https://github.com/GSA/notifications-admin/issues/96 to make
+the UI adjustments.

+## CONTEXT AND PROBLEM STATEMENT
+**OPEN ISSUE(S):** https://github.com/GSA/notifications-admin/issues/539, https://github.com/GSA/notifications-admin/issues/521, https://github.com/GSA/notifications-admin/issues/566
+
+The initial launch of the beta.notify.gov site requires minimal public-facing content and must remove self-service account creation from the general public, as per communications oversight within TTS.
+
+## DECISION DRIVERS
+
+### Desired outcomes:
+- A clean, informative landing page at beta.notify.gov that allows for closed pilot partners to access the application
+- No ability for members of the public to create an account or view "how-to" documentation
+
+### Primary concerns:
+- Removing the self-service option altogether creates more work on the team members, who have to create an account/service
+- Removing the self-service option obviates the initial service creator from progressing through the `service creation wizard` content
+- LOE to make currently publicly visible documentation only accessible after login
+
+## SECURITY COMPLIANCE CONSIDERATIONS
+Because we work in a regulated space with many compliance requirements, we need to make sure we're accounting for any security concerns and adhering to all security compliance requirements. List them in this section along with any relevant details:
+
+**Security concern**
+
+N/A
+
+## CONSIDERED OPTIONS
+List all options that have either been discussed or thought of as a potential solution to the context and problem statement. Include any pros and cons with each option, like so:
+
+### Option 1: A minimal landing page with only a short info paragraph, a closed pilot statement, and sign-in button, completely removing the ability to create a service except if done by a Studio team member. All other pages are only accessible after login.
+
+**Pros:**
+
+- Simplest and least amount of content (ergo, requires least review/approval)
+- No need to scope a gated self-service solution
+
+**Cons:**
+
+- `Service creation wizard` content is not seen by pilot users
+- More work on Studio team to construct a process to get pilot partners initial account access/service creation
+
+### Option 2: A landing page with sign-in button, pilot statement, and a small amount of "marketing" type content, completely removing the ability to create a service except if done by a Studio team member. All other pages are only accessible after login.
+
+**Pros:**
+
+- Allows for public vistors to know more about what the product is intended to do
+- No need to scope a gated self-service solution
+
+ **Cons:**
+
+- `Service creation wizard` content is not seen by pilot users
+- More work on Studio team to construct a process to get pilot partners initial account access/service creation
+- More content to review by oversight teams
+
+### Option 3: A minimal landing page that offers a sign-in button AND a field to input a pilot invite code, which would allow a user to then self-service create an account and initial service. All other pages are only accessible after login.
+
+**Pros:**
+
+- Invited users would go throught the `service creation wizard` flow and content
+- A Studio team member would not need to create the initial account/service
+
+**Cons:**
+
+- Scoping and implementing an invite code system could cost many developer hours
+- The action of creating an invite code for a user may end up being as burdensome as creating the initial account/service, nullifying the team time saved
+
+## PROPOSED OR CHOSEN OPTION: Option 2
+Option 2 provides the most benefit with least Studio work required. When weighing the value of the `service creation wizard` content/flow, we considered that it is 1. ephemeral (users can only access it once) and 2. limited to the service creator, rather than all team members. For the potential work to devise an invite code option, it did not feel that the benefit of the `wizard` outweighed the cost. Additionally, we resolve to explore replicating the `wizard` content/flow into another part of the site that can be accessed as frequently as necessary, and by all users of the application.

+| 06/21/2023 | 07/05/2023 | Accepted | @stvnrlly, @ccostino | @GSA/notify-contributors |
+
+
+## CONTEXT AND PROBLEM STATEMENT
+
+**OPEN ISSUE(S):**
+* https://github.com/GSA/notifications-api/issues/141
+* https://github.com/GSA/notifications-admin/issues/53
+* https://github.com/GSA/notifications-admin/issues/51
+
+We will be entering into Memoranda of Understanding (MOU) and Interagency
+Agreements (IAA) with partner agencies. Data from those agreements will be
+important for application function.
+
+Unlike the UK version of the application, users will not be able to complete a
+self-service in-app agreement process. Our agreement process requires that
+documents be “signed” outside of the application and (especially in the case of
+an IAA) needs to happen with specific forms that have historically proven
+difficult to automate.
+
+Inside the application, we’ll want to know information about the partner as well
+as information necessary to avoid overspending the account.
+
+This information includes:
+- Agreement identifier
+- Agreement type (MOU or IAA)
+- Agreement partner name
+- Agreement status
+- Agreement start datetime (known as period of performance)
+- Agreement end datetime (known as period of performance)
+- Agreement URL (where it is in Google Drive)
+- Budget amount (*not* message limit)
+
+
+## DECISION DRIVERS
+
+An implementation should address these needs:
+
+- The need for multiple agreements per partner over time
+- The information and tools to stop sending before overspending
+- The ability to connect data to organization and service models
+
+This is a minimal implementation of agreement data. It's quite possible that
+it will change and expand over time, but those needs are not yet clear.
+
+Because we will continue to have the actual agreement docs safely in Google
+Drive, this implementation does not need to be a source of truth and does not
+need to retain history over time.
+
+
+### SECURITY COMPLIANCE CONSIDERATIONS
+
+We will need to take care about permissions to change this data. Existing
+permissions are fairly binary: you are a user or you are an admin. We should
+consider whether that's still sufficient or if an in-between role would be
+useful.
+
+
+## CONSIDERED OPTIONS
+
+As a team, we've gone through the following options:
+
+- Add an Agreement model: a new class in `models.py` with the relevant fields.
+  - Pros:
+    - Separates agreements from the orgs, since they may change separately
+    - Multiple agreement-like models might be confusing, this avoids that
+  - Cons:
+    - Groups IAA and MOU together, which makes validation at the model level
+      harder and, in turn, makes it easier to break validation logic elsewhere
+      in the application
+
+- Add MOU and IAA models: two new classes in `models.py` with the same fields
+  but different configurations.
+  - Pros:
+    - Cleanest representation of the real world
+    - Allows SQL-level support for required/unique fields
+  - Cons:
+    - Most complex data model
+
+- Add agreement info to Organization model: no new classes, just a combination
+  of new fields and properties.
+  - Pros:
+    - No added model complexity
+  - Cons:
+    - Doesn’t directly allow for history
+
+
+## CHOSEN OPTION: Add an Agreement model
+
+By adding an Agreement model, we’ll allow flexibility in the interaction between
+agreements and organizations but stop short of attempting to recreate the full
+complexity of agreements in our data model.
+
+If we later find that it’s necessary to separate MOU and IAA agreements, we
+should be able to perform a migration.
+
+
+### Consequences
+
+- Positive
+  - We’ll gain more granular control over message limits for paid (IAA)
+    agreements
+  - We can offer more agreement transparency to users. For example, identifying
+    agreements that will need renewal
+
+- Negative
+  - We’re adding some complexity to the data model
+  - We know that this implementation is an MVP and thus might have rough edges
+  - Manual work is necessary to keep agreements in sync with the real-world
+    process
+
+
+## VALIDATION AND NEXT STEPS
+
+This process includes adding the new model and updating the existing models to
+use them.
+
+1. Add the new model:
+   - Add Agreement to models.py with the fields identified above
+   - Create migration to add/update table
+
+2. Update the Organization model:
+   - Add one-to-many field linking one Organization to multiple Agreements
+   - Add model property to convert budget amount into message limit
+   - Add model property to provide remaining budget based on sent messages
+   - Add model property about whether free tier or not
+   - Add model property for free tier usage (retrieve messages sent in a year)
+
+This will set up a new system, but stops short of connecting agreements to the
+services actually sending the messages. This approach will be laid out in a
+forthcoming ADR about managing message limits.

+# US Notify Architectural Decision Records (ADRs)
+
+This sub-folder in the US Notify API project contains the bulk of our
+Architectural Decision Records (henceforth referred to as ADRs) for the overall
+product and service.
+
+
+## What are ADRs?
+
+ADRs serve a few purposes for our team:
+
+- Document important decisions related to the behavior, architecture, and/or
+  dependencies of the platform
+- Capture the decision making process behind a change, from its initial proposal
+  all the way through to its decided outcomes
+- Identify alternative approaches and note why they were ultimately not chosen
+- Denote who is the decision maker(s) for a change within the team
+
+The collection of ADRs in this repository make up our architectural decision log
+(ADL).  An index of the log is maintained right here in this README just below.
+
+For more information, you can see the details in
+[our first ADR](./0001-establishing-adrs-for-us-notify.md) that establishes
+everything!
+
+
+## When should we write an ADR?
+
+An ADR should be written when the team is discussing any significant change to
+the system that will alter its behavior, infrastructure, and/or dependencies.
+
+We should also consider writing an ADR when we're ready to propose something
+that is new to the system, e.g., adding a new feature, leveraging a new cloud
+service for additional capabilities, etc.  An ADR is a great format to write a
+proposal and then share it with the rest of the team to discuss it and decide
+whether or not to move forward, with or without any changes.
+
+
+## How are ADRs created, reviewed, and maintained?
+
+First, we have an ADR template that folks can use to work off of.  The template
+exists as both a GitHub issue template and a standalone Markdown file that can
+be copied as needed if folks prefer to work locally first.
+
+By following the template, we ensure that our ADRs are consistent in language
+and structure.  This allows us to easily review the documentions and discuss
+them as a team.  It also guarantees that the ADR has all of the required
+information.
+
+**ADRs are intended to be living documents.**  As such, it is not uncommon to
+see multiple pull requests (PRs) filed to update them, especially during an
+active discussion and research taking place.  This is also why there is a
+*status* marker on them as a part of their metadata.
+
+Once an ADR has been reviewed and is ready to be finalized (either as accepted,
+rejected, or some other status), some final edits are made to update the ADR
+with decision details and next steps.  After this, future PRs can be opened to
+make additional updates, especially if an ADR becomes deprecated or superceded
+by another one.
+
+
+### Draft and Private ADRs
+
+For ADRs that we are collaborating over in real-time or much more synchronously
+as opposed to PR reviews and such, and/or storing private ADRs that we cannot
+share publicly, we have an
+:lock: [Architectural Decision Record Drive folder](https://drive.google.com/drive/folders/1APnbNZ81AuhZ8RFSyU5i9m_ZIetdHc-Q)
+to store these documents in.
+
+For Draft ADRs that can become **public**, once they're in a state that there
+isn't as a great a need for synchronous collaboration they can be copied to a
+Markdown file using the ADR template in GitHub and moved here, following the
+process we have outlined in this document.
+
+For ADRs that must remain **private**, there is a place to store them in the
+aforementioned Drive folder once they're in a finalized state.  We will still
+reference them in the Architectural Decision Log below, but there either won't
+be links or the link will go to a :lock: *private document* instead.
+
+
+### Creating an ADR
+
+To create a new ADR in this repository, you can do one of two things:
+
+- Open a new GitHub issue and select the Architecture Decision Record issue type
+- Clone the repo locally, create a new branch for yourself, and make a copy of
+  the Markdown template
+
+In either scenario, check to see what the latest ADR filename is, because they
+always start with a number (e.g., `0001`).  Name your ADR with a number one
+after the last ADR written; if the latest ADR starts with `0021-`, your ADR
+should start with `0022-`.
+
+At this point, it is a matter of filling in the details outlined in the template
+that are relevant to the ADR.
+
+
+### Reviewing an ADR
+
+Once an ADR is created, it's time for review and discussion!  This could happen
+a few ways:
+
+- Asynchronously via comments on the pull request itself
+- Synchronously with a scheduled meeting(s) and a facilitator
+- A combination of these, depending on the nature of the ADR and needs of the
+  team
+
+Whichever way is chosen, the review process should allow the team to dig into
+the proposal and talk through its merits, address anything needing
+clarification, discuss any potential alternatives, and develop an understanding
+of the trade-offs in deciding to move forward with the proposal or not.
+
+If it turns out that one of the alternatives proves to be a better solution, the
+ADR should be updated to reflect that and a follow-up discussion and/or review
+should be held to make sure everything is accurate and up-to-date.
+
+**Please note:** Similar to sprint retrospectives, these review sessions *must*
+ensure a healthy and open dialog within the team; therefore, we actively work
+to promote psychological safety so that everyone and their contributions are
+welcomed and respected.
+
+As a reminder, we can reference these statements, just as we would in a sprint
+retrospective:
+
+>We are here to improve our team and our way of working incrementally over time.
+>This is a safe space, where we can openly discuss anything related to the team
+>or project in a [blameless manner](https://opensource.com/article/19/4/psychology-behind-blameless-retrospective).
+
+[Retrospective Prime Directive](https://retrospectivewiki.org/index.php?title=The_Prime_Directive):
+
+>“Regardless of what we discover, we understand and truly believe that everyone
+>did the best job they could, given what they knew at the time, their skills and
+>abilities, the resources available, and the situation at hand.”
+
+*– Norm Kerth, Project Retrospectives:  A Handbook for Team Review*
+
+An approach we can take during the discussions is to use the principles of
+:lock: [The Art of Alignment](https://drive.google.com/file/d/1pPIzJG1kcnudR1HjZiB5UZgwYJ1dyetS/view?usp=share_link).
+There are also other frameworks and tools for sharing proposals and achieving
+consensus within a team.
+
+
+### Maintaining an ADR
+
+If an ADR requires some updates or is ready to be accepted or rejected, you can
+either edit the file directly in GitHub or create a new branch in the repo on
+your local machine and make the changes necessary.
+
+In either scenario, you'll create a pull request (PR) with your changes that
+will then be ready for review from others on the team.
+
+ADR statuses can be one of the following:
+
+- Proposed
+- Accepted
+- Rejected
+- Deprecated
+- Superseded By (new ADR number and link)
+
+There is also a field for tracking if an ADR is implemented or not (`Yes` or
+`No`).
+
+Once the ADR itself is updated, this README also needs to be updated so that the
+ADR is listed in the Architecture Decision Log just below.  This lists all of
+our ADRs in reverse chronological order so we have a convenient index of them.
+
+

+top!).

+# Infrastructure overview
+
+A diagram of the system is available [in our compliance repo](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/application.boundary.png).
+
+Notify is a Flask application running on [cloud.gov](https://cloud.gov), which also brokers access to a PostgreSQL database and Redis store.
+
+In addition to the Flask app, Notify uses Celery to manage the task queue. Celery stores tasks in Redis.
+
+## GitHub Repositories
+
+Application, infrastructure, and compliance work is spread across several repositories:
+
+### Application
+
+* [notifications-api](https://github.com/GSA/notifications-api) for the API app
+* [notifications-admin](https://github.com/GSA/notifications-admin) for the Admin UI app
+* [notifications-utils](https://github.com/GSA/notifications-utils) for common library functions
+
+### Infrastructure
+
+In addition to terraform directories in the api and admin apps above:
+
+#### We maintain:
+
+* [usnotify-ssb](https://github.com/GSA/usnotify-ssb) A supplemental service broker that provisions SES and SNS for us
+* [ttsnotify-brokerpak-sms](https://github.com/GSA/ttsnotify-brokerpak-sms) The brokerpak defining SNS (SMS sending)
+
+#### We use:
+
+* [datagov-brokerpak-smtp](https://github.com/GSA-TTS/datagov-brokerpak-smtp) The brokerpak defining SES
+* [cg-egress-proxy](https://github.com/GSA-TTS/cg-egress-proxy/) The caddy proxy that allows external API calls
+
+### Compliance
+
+* [us-notify-compliance](https://github.com/GSA/us-notify-compliance) for OSCAL control documentation and diagrams
+
+## Terraform
+
+### Development
+
+There are several remote services required for local development:
+
+* s3
+* ses
+* sns
+
+Credentials for these services are created by running:
+
+1. `cd terraform/development`
+1. `./run.sh`
+
+in both the api repository as well as the admin repository.
+
+This will append credentials to your `.env` file. You will need to manually clean up any prior runs from that file if you run that command again.
+
+You can remove your development infrastructure by running `./run.sh -d`
+
+#### Resetting
+
+`./reset.sh` can be used to import your development infrastructure information in case of a new computer or new working tree and the old terraform state file was not transferred.
+
+#### Offboarding
+
+`./reset.sh -u USER_TO_OFFBOARD` can be used to import another user's development resources in order to clean them up. Steps for use:
+
+1. Move your existing terraform state file aside temporarily, so it is not overwritten.
+1. `./reset.sh -u USER_TO_OFFBOARD`
+1. Answer no to the prompt about creating missing resources.
+1. Run `./run.sh -u USER_TO_OFFBOARD -d` to fully remove the rest of that user's resources.
+
+### Cloud.gov
+
+The cloud.gov environment is configured with Terraform. See [the `terraform` folder](../terraform/) to learn about that.
+
+## AWS
+
+In addition to services provisioned through cloud.gov, we have several services provisioned via [supplemental service brokers](https://github.com/GSA/usnotify-ssb) in AWS. Our AWS services are currently located in [several regions](https://github.com/GSA/usnotify-ssb#aws-accounts-and-regions-in-use) using Studio-controlled AWS accounts.
+
+To send messages, we use Amazon Web Services SNS and SES. In addition, we use AWS Pinpoint to provision and manage phone numbers, short codes, and long codes for sending SMS.
+
+In SNS, we have 3 topics for SMS receipts. These are not currently functional, so senders won't know the status of messages.
+
+Through Pinpoint, the API needs at least one number so that the application itself can send SMS for authentication codes.
+
+The API also has access to AWS S3 buckets for storing CSVs of messages and contact lists. It does not access a third S3 bucket that stores agency logos.
+
+## New Relic
+
+We are using [New Relic](https://one.newrelic.com/nr1-core?account=3389907) for application monitoring and error reporting. When requesting access to New Relic, ask to be added to the Benefits-Studio subaccount.
+
+## Onboarding
+
+- [ ] Join [the GSA GitHub org](https://github.com/GSA/GitHub-Administration#join-the-gsa-organization)
+- [ ] Get permissions for the repos
+- [ ] Get access to the cloud.gov org && spaces
+- [ ] Get [access to AWS](https://handbook.tts.gsa.gov/launching-software/infrastructure/#cloud-service-provider-csp-sandbox-accounts), if necessary
+- [ ] Get [access to New Relic](https://handbook.tts.gsa.gov/tools/new-relic/#how-do-i-get-access-to-new-relic), if necessary
+- [ ] Create the local `.env` file by copying `sample.env` and running `./run.sh` within the `terraform/development` folder
+- [ ] Do stuff!
+
+## Setting up the infrastructure
+
+These steps are required for new cloud.gov environments. Local development borrows SES & SNS infrastructure from the `notify-staging` cloud.gov space, so these steps are not required for new developers.
+
+### Steps to do a clean prod deploy to cloud.gov
+
+Steps for deploying production from scratch. These can be updated for a new cloud.gov environment by subbing out `prod` or `production` for your desired environment within the steps.
+
+1. Deploy API app
+    1. Update `terraform-production.yml` and `deploy-prod.yml` to point to the correct space and git branch.
+    1. Ensure that the `domain` module is commented out in `terraform/production/main.tf`
+    1. Run CI/CD pipeline on the `production` branch by opening a PR from `main` to `production`
+    1. Create any necessary DNS records (check `notify-api-ses-production` service credentials for instructions) within https://github.com/18f/dns
+    1. Follow the `Steps to prepare SES` below
+    1. (Optional) if using a public API route, uncomment the `domain` module and re-trigger a deploy
+1. Deploy Admin app
+    1. Update `terraform-production.yml` and `deploy-prod.yml` to point to the correct space and git branch.
+    1. Ensure that the `api_network_route` and `domain` modules are commented out in `terraform/production/main.tf`
+    1. Run CI/CD pipeline on the `production` branch by opening a PR from `main` to `production`
+    1. Create DNS records for `domain` module within https://github.com/18f/dns
+    1. Uncomment the `api_network_route` and `domain` modules and re-trigger a deploy
+
+### Steps to prepare SES
+
+1. After the first deploy of the application with the SSB-brokered SES service completes:
+    1. Log into the SES console and navigate to the SNS subscription page.
+    1. Select "Request confirmation" for any subscriptions still in "Pending Confirmation" state
+1. Find and replace instances in the repo of "testsender", "testreceiver" and "dispostable.com", with your origin and destination email addresses, which you verified in step 1 above.
+
+TODO: create env vars for these origin and destination email addresses for the root service, and create new migrations to update postgres seed fixtures
+
+### Steps to prepare SNS
+
+#### Move SNS out of sandbox.
+
+This should be complete for all regions U.S. Notify has been deployed to or is currently planned to be deployed to.
+
+1. Visit the SNS console for the region you will be sending from. Notes:
+    1. SNS settings are per-region, so each environment must have its own region
+    1. Pinpoint and SNS have confusing regional availability, so ensure both are available before submitting any requests.
+1. Choose `Text messaging (SMS)` from the sidebar
+1. Click the `Exit SMS Sandbox` button and submit the support request. This request should take at most a day to complete. Be sure to request a higher sending limit at the same time.
+
+#### Request new phone numbers
+
+1. Go to Pinpoint console for the same region you are using SNS in.
+1. In the lefthand sidebar, go the `SMS and Voice` (bottom) and choose `Phone Numbers`
+1. Under `Number Settings` choose `Request Phone Number`
+1. Choose Toll-free number, tick SMS, untick Voice, choose `transactional`, hit next and then `request`
+1. Select `Toll-free registrations` and `Create registration`
+1. Select the number you just created and then `Register existing toll-free number`
+1. Complete and submit the form. Approval usually takes about 2 weeks.
+1. See the [run book](./run-book.md) for information on how to set those numbers.
+
+Example answers for toll-free registration form
+
+![example answers for toll-free registration form](./toll-free-registration.png)
+
+# Testing
+
+```
+# install dependencies, etc.
+make bootstrap
+
+make test
+```
+
+This will run:
+- flake8 for code styling
+- isort for import styling
+- pytest for the test suite
+
+On GitHub, in addition to these tests, we run:
+- bandit for code security
+- pip-audit for dependency vulnerabilities
+- OWASP for dynamic scanning
+
+## CI testing
+
+We're using GitHub Actions. See [/.github](../.github/) for the configuration.
+
+In addition to commit-triggered scans, the `daily_checks.yml` workflow runs the relevant dependency audits, static scan, and/or dynamic scans at 10am UTC each day. Developers will be notified of failures in daily scans by GitHub notifications.
+
+### Nightly Scans
+
+Within GitHub Actions, several scans take place every day to ensure security and compliance.
+
+
+#### [daily-checks.yml](../.github/workflows/daily_checks.yml)
+
+`daily-checks.yml` runs `pip-audit`, `bandit`, and `owasp` scans to ensure that any newly found vulnerabilities do not impact notify. Failures should be addressed quickly as they will also block the next attempted deploy.
+
+#### [drift.yml](../.github/workflows/drift.yml)
+
+`drift.yml` checks the deployed infrastructure against the expected configuration. A failure here is a flag to check audit logs for unexpected access and/or behavior and potentially destroy and re-deploy the application. Destruction and redeployment of all underlying infrastructure is an extreme remediation, and should only be attempted after ensuring that a good database backup is in hand.
+
+## Manual testing
+
+If you're checking out the system locally, you may want to create a user quickly.
+
+`pipenv run flask command create-test-user`
+
+This will run an interactive prompt to create a user, and then mark that user as active. *Use a real mobile number* if you want to log in, as the SMS auth code will be sent here.
+
+## To run a local OWASP scan
+
+1. Run `make run-flask` from within the dev container.
+2. On your host machine run:
+
+```
+docker run -v $(pwd):/zap/wrk/:rw --network="notify-network" -t owasp/zap2docker-weekly zap-api-scan.py -t http://dev:6011/docs/openapi.yml -f openapi -c zap.conf
+```
+
+The equivalent command if you are running the API locally:
+
+```
+docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-weekly zap-api-scan.py -t http://host.docker.internal:6011/docs/openapi.yml -f openapi -c zap.conf -r report.html
+```
+
+
+# Deploying
+
+We deploy automatically to cloud.gov for production, demo, and staging environments.
+
+Deployment to staging runs via the [base deployment action](../.github/workflows/deploy.yml) on GitHub, which pulls credentials from GitHub's secrets store in the staging environment.
+
+Deployment to demo runs via the [demo deployment action](../.github/workflows/deploy-demo.yml) on GitHub, which pulls credentials from GitHub's secrets store in the demo environment.
+
+Deployment to production runs via the [production deployment action](../.github/workflows/deploy-prod.yml) on GitHub, which pulls credentials from GitHub's secrets store in the production environment.
+
+The [action that we use](https://github.com/18F/cg-deploy-action) deploys using [a rolling strategy](https://docs.cloudfoundry.org/devguide/deploy-apps/rolling-deploy.html), so all deployments should have zero downtime.
+
+The API has 3 deployment environments:
+
+- Staging, which deploys from `main`
+- Demo, which deploys from `production`
+- Production, which deploys from `production`
+
+Configurations for these are located in [the `deploy-config` folder](../deploy-config/).
+
+In the event that a deployment includes a Terraform change, that change will run before any code is deployed to the environment. Each environment has its own Terraform GitHub Action to handle that change.
+
+Failures in any of these GitHub workflows will be surfaced in the Pull Request related to the code change, and in the case of `checks.yml` actively prevent the PR from being merged. Failure in the Terraform workflow will not actively prevent the PR from being merged, but reviewers should not approve a PR with a failing terraform plan.
+
+## Egress Proxy
+
+The API app runs in a [restricted egress space](https://cloud.gov/docs/management/space-egress/).
+This allows direct communication to cloud.gov-brokered services, but
+not to other APIs that we require.
+
+As part of the deploy, we create an
+[egress proxy application](https://github.com/GSA/cg-egress-proxy) that allows traffic out of our
+application to a select list of allowed domains.
+
+Update the allowed domains by updating `deploy-config/egress_proxy/notify-api-<env>.allow.acl`
+and deploying an updated version of the application throught he normal deploy process.
+
+## Sandbox environment
+
+There is a sandbox space, complete with terraform and `deploy-config/sandbox.yml` file available
+for experimenting with infrastructure changes without going through the full CI/CD cycle each time.
+
+Rules for use:
+
+1. Ensure that no other developer is using the environment, as there is nothing stopping changes from overwriting each other.
+1. Clean up when you are done:
+    - `terraform destroy` from within the `terraform/sandbox` directory will take care of the provisioned services
+    - Delete the apps and routes shown in `cf apps` by running `cf delete APP_NAME -r`
+    - Delete the space deployer you created by following the instructions within `terraform/sandbox/secrets.auto.tfvars`
+
+### Deploying to the sandbox
+
+1. Set up services:
+    ```
+    $ cd terraform/sandbox
+    $ ../create_service_account.sh -s notify-sandbox -u <your-name>-terraform -m > secrets.auto.tfvars
+    $ terraform init
+    $ terraform plan
+    $ terraform apply
+    ```
+1. start a pipenv shell as a shortcut to load `.env` file variables: `$ pipenv shell`
+1. Output requirements.txt file: `pipenv requirements > requirements.txt`
+1. Deploy the application:
+  ```
+  cf push --vars-file deploy-config/sandbox.yml --var NEW_RELIC_LICENSE_KEY=$NEW_RELIC_LICENSE_KEY
+  ```
+
+
+# Database management
+
+## Initial state
+
+In Notify, several aspects of the system are loaded into the database via migration. This means that
+application setup requires loading and overwriting historical data in order to arrive at the current
+configuration.
+
+[Here are notes](https://docs.google.com/document/d/1ZgiUtJFvRBKBxB1ehiry2Dup0Q5iIwbdCU5spuqUFTo/edit#)
+about what is loaded into which tables, and some plans for how we might manage that in the future.
+
+Flask does not seem to have a great way to squash migrations, but rather wants you to recreate them
+from the DB structure. This means it's easy to recreate the tables, but hard to recreate the initial data.
+
+## Data Model Diagram
+
+A diagram of Notify's data model is available [in our compliance repo](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/data.logical.pdf).
+
+## Migrations
+
+Create a migration:
+
+```
+flask db migrate
+```
+
+Trim any auto-generated stuff down to what you want, and manually rename it to be in numerical order.
+We should only have one migration branch.
+
+Running migrations locally:
+
+```
+flask db upgrade
+```
+
+This should happen automatically on cloud.gov, but if you need to run a one-off migration for some reason:
+
+```
+cf run-task notifications-api-staging --commmand "flask db upgrade" --name db-upgrade
+```
+
+## Purging user data
+
+There is a Flask command to wipe user-created data (users, services, etc.).
+
+The command should stop itself if it's run in a production environment, but, you know, please don't run it
+in a production environment.
+
+Running locally: 
+
+```
+flask command purge_functional_test_data -u <functional tests user name prefix>
+```
+
+Running on cloud.gov:
+
+```
+cf run-task notify-api "flask command purge_functional_test_data -u <functional tests user name prefix>"
+```
+
+
+# One-off tasks
+
+For these, we're using Flask commands, which live in [`/app/commands.py`](../app/commands.py).
+
+This includes things that might be one-time operations! If we're running it on production, it should be a Flask 
+command Using a command allows the operation to be tested, both with `pytest` and with trial runs in staging.
+
+To see information about available commands, you can get a list with:
+
+`pipenv run flask command`
+
+Appending `--help` to any command will give you more information about parameters.
+
+To run a command on cloud.gov, use this format:
+
+`cf run-task CLOUD-GOV-APP --commmand "YOUR COMMAND HERE" --name YOUR-COMMAND`
+
+[Here's more documentation](https://docs.cloudfoundry.org/devguide/using-tasks.html) about Cloud Foundry tasks.
+
+# How messages are queued and sent
+
+There are several ways for notifications to come into the API.
+
+- Messages sent through the API enter through `app/notifications/post_notifications.py`
+- One-off messages sent from the UI enter through `create_one_off_notification` in `app/service/rest.py`
+- CSV uploads enter through `app/job/rest.py`
+
+API messages and one-off UI messages come in one at a time, and take slightly-separate routes
+that both end up at `persist_notification`, which writes to the database, and `provider_tasks.deliver_sms`,
+which enqueues the sending.
+
+For CSV uploads, the CSV is first stored in S3 and queued as a `Job`. When the job runs, it iterates
+through the rows, running `process_job.save_sms` to send notifications through `persist_notification` and 
+`provider_tasks.deliver_sms`.
+
+# Writing public APIs
+
+_Most of the API endpoints in this repo are for internal use. These are all defined within top-level folders under `app/` and tend to have the structure `app/<feature>/rest.py`._
+
+## Overview
+
+Public APIs are intended for use by services and are all located under `app/v2/` to distinguish them from internal endpoints. Originally we did have a "v1" public API, where we tried to reuse / expose existing internal endpoints. The needs for public APIs are sufficiently different that we decided to separate them out. Any "v1" endpoints that remain are now purely internal and no longer exposed to services.
+
+## Documenting APIs
+
+New and existing APIs should be documented within [openapi.yml](./openapi.yml). Tools to help
+with editing this file:
+
+* [OpenAPI Editor for VSCode](https://marketplace.visualstudio.com/items?itemName=42Crunch.vscode-openapi)
+* [OpenAPI specification](https://spec.openapis.org/oas/v3.0.2)
+
+
+## New APIs
+
+Here are some pointers for how we write public API endpoints.
+
+### Each endpoint should be in its own file in a feature folder
+
+Example: `app/v2/inbound_sms/get_inbound_sms.py`
+
+This helps keep the file size manageable but does mean a bit more work to register each endpoint if we have many that are related. Note that internal endpoints are grouped differently: in large `rest.py` files.
+
+### Each group of endpoints should have an `__init__.py` file
+
+Example:
+
+```
+from flask import Blueprint
+
+from app.v2.errors import register_errors
+
+v2_notification_blueprint = Blueprint("v2_notifications", __name__, url_prefix='/v2/notifications')
+
+register_errors(v2_notification_blueprint)
+```
+
+Note that the error handling setup by `register_errors` (defined in [`app/v2/errors.py`](../app/v2/errors.py)) for public API endpoints is different to that for internal endpoints (defined in [`app/errors.py`](../app/errors.py)).
+
+### Each endpoint should have an adapter in each API client
+
+Example: [Ruby Client adapter to get template by ID](https://github.com/alphagov/notifications-ruby-client/blob/d82c85452753b97e8f0d0308c2262023d75d0412/lib/notifications/client.rb#L110-L115).
+
+All our clients should fully support all of our public APIs.
+
+Each adapter should be documented in each client ([example](https://github.com/alphagov/notifications-ruby-client/blob/d82c85452753b97e8f0d0308c2262023d75d0412/DOCUMENTATION.md#get-a-template-by-id)). We should also document each public API endpoint in our generic API docs ([example](https://github.com/alphagov/notifications-tech-docs/blob/2700f1164f9d644c87e4c72ad7223952288e8a83/source/documentation/_api_docs.md#send-a-text-message)). Note that internal endpoints are not documented anywhere.
+
+### Each endpoint should specify the authentication it requires
+
+This is done as part of registering the blueprint in `app/__init__.py` e.g.
+
+```
+post_letter.before_request(requires_auth)
+application.register_blueprint(post_letter)
+```
+
+# API Usage
+
+## Connecting to the API
+
+To make life easier, the [UK API client libraries](https://www.notifications.service.gov.uk/documentation) are compatible with Notify and the [UK API Documentation](https://docs.notifications.service.gov.uk/rest-api.html) is applicable.
+
+For a usage example, see [our Python demo](https://github.com/GSA/notify-python-demo).
+
+An API key can be created at https://HOSTNAME/services/YOUR_SERVICE_ID/api/keys. This is the same API key that is referenced as `USER_API_TOKEN` below.
+
+## Postman Documentation
+
+Internal-only  [documentation for exploring the API using Postman](https://docs.google.com/document/d/1S5c-LxuQLhAtZQKKsECmsllVGmBe34Z195sbRVEzUgw/edit#heading=h.134fqdup8d3m)
+
+
+## Using OpenAPI documentation
+
+An [OpenAPI](https://www.openapis.org/) specification [file](./openapi.yml) can be found at https://notify-staging.app.cloud.gov/docs/openapi.yml.
+
+See [writing-public-apis.md](./writing-public-apis.md) for links to tools to make it easier to use the OpenAPI spec within VSCode.
+
+### Retrieving a jwt-encoded bearer token for use
+
+On a mac, run:
+
+#### Admin UI token
+
+The admin UI token is required for any of the `internal-api` tagged methods. To create one and copy it to your pasteboard, run:
+
+```
+flask command create-admin-jwt | tail -n 1 | pbcopy
+```
+
+#### User token
+
+A user token is required for any of the `external-api` tagged methods. To create one and copy it to your pasteboard, run:
+
+```
+flask command create-user-jwt --token=<USER_API_TOKEN> | tail -n 1 | pbcopy
+```
+
+### Disable token expiration checking in development
+
+Because jwt tokens expire so quickly, the development server can be set to allow tokens older than 30 seconds:
+
+```
+env ALLOW_EXPIRED_API_TOKEN=1 make run-flask
+```
+
+
+
+# Queues and tasks
+
+The API puts tasks into Celery queues for dispatch.
+
+There are a bunch of queues:
+- priority tasks
+- database tasks
+- send sms tasks
+- send email tasks
+- research mode tasks
+- reporting tasks
+- job tasks
+- retry tasks
+- notify internal tasks
+- service callbacks
+- service callbacks retry
+- letter tasks
+- sms callbacks
+- antivirus tasks
+- save api email tasks
+- save api sms tasks
+
+And these tasks:
+- check for missing rows in completed jobs
+- check for services with high failure rates or sending to tv numbers
+- check if letters still in created
+- check if letters still pending virus check
+- check job status
+- create fake letter response file
+- create nightly billing
+- create nightly billing for day
+- create nightly notification status
+- create nightly notification status for service and day
+- delete email notifications
+- delete inbound sms
+- delete invitations
+- delete letter notifications
+- delete notifications for service and type
+- delete notifications older than retention
+- delete sms notifications
+- delete verify codes
+- deliver email
+- deliver sms
+- process incomplete jobs
+- process job
+- process returned letters list
+- process ses result
+- process virus scan error
+- process virus scan failed
+- raise alert if letter notifications still sending
+- raise alert if no letter ack file
+- record daily sorted counts
+- remove letter jobs
+- remove sms email jobs
+- replay created notifications
+- run scheduled jobs
+- save api email
+- save api sms
+- save daily notification processing time
+- save email
+- save letter
+- save sms
+- send complaint
+- send delivery status
+- send inbound sms
+- switch current sms provider on slow delivery
+- tend providers back to middle
+- timeout sending notifications
+- update billable units for letter
+- update letter notifications statuses
+- update letter notifications to error
+- update letter notifications to sent
+- update validation failed for templated letter
+
+## Priority queue
+
+For tasks that should happen before other stuff, there's a priority queue. Platform admins
+can set templates to use this queue.
+
+Currently, this queue doesn't do anything special. If the normal queue is very busy, it's
+possible that this queue will be faster merely because it's shorter. By the same logic, a 
+busy priority queue is likely to be _slower_ than the normal queue

+US Notify
+=========
+
+System Description
+------------------
+
+US Notify is a service being developed by the TTS Public Benefits Studio to increase the availability of
+SMS and email notifications to Federal, State, and Local Benefits agencies.
+
+Agencies that sign up will be able to create and use personalized message templates for sending
+notifications to members of the public regarding their benefits. These could include reminders
+about upcoming enrollment deadlines and tasks, or information about upcoming appointments, events,
+or services.
+
+The templates are sent by the agency using one of two methods:
+
+* using the US Notify API to send a message to a given recipient with given personalization values
+* using the US Notify website to upload a CSV file of recipients and their personalization values, one row per message
+
+### Environment
+
+US Notify is comprised of two applications both running on cloud.gov:
+
+* Admin, a Flask website running on the python_buildpack which hosts agency user-facing UI
+* API, a Flask application running on the python_buildpack hosting the US Notify API
+
+US Notify utilizes several cloud.gov-provided services:
+
+* S3 buckets for temporary file storage
+* Elasticache (redis) for cacheing data and enqueueing background tasks
+* RDS (PostgreSQL) for system data storage
+
+US Notify also provisions and uses two AWS services via a [supplemental service broker](https://github.com/GSA/usnotify-ssb):
+
+* [SNS](https://aws.amazon.com/sns/) for sending SMS messages
+* [SES](https://aws.amazon.com/ses/) for sending email messages
+
+For further details of the system and how it connects to supporting services, see the [application boundary diagram](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/application.boundary.png)
+
+
+Run Book
+========
+
+Policies and Procedures needed before and during US Notify Operations. Many of these policies are taken from the U.S. Notify System Security & Privacy Plan (SSPP).
+
+Any changes to policies and procedures defined both here and in the SSPP must be kept in sync, and should be done collaboratively with the System ISSO and ISSM to ensure
+that the security of the system is maintained.

+
+## <a name="alerts"></a> Alerts, Notifications, Monitoring
+
+Operational alerts are posted to the [#pb-notify-alerts](https://gsa-tts.slack.com/archives/C04U9BGHUDB) Slack channel. Please join this channel and enable push notifications for all messages whenever you are on call.
+
+[NewRelic](https://one.newrelic.com/) is being used for monitoring the application. [NewRelic Dashboard](https://onenr.io/08wokrnrvwx) can be filtered by environment and API, Admin, or Both.
+
+[Cloud.gov Logging](https://logs.fr.cloud.gov/) is used to view and search application and platform logs.
+
+In addition to the application logs, there are several tables in the application that store useful information for audit logging purposes:
+
+* `events`
+* the various `*_history` tables
+
+
+## <a name="restaging-apps"></a> Restaging Apps
+
+Our apps must be restaged whenever cloud.gov releases updates to buildpacks. Cloud.gov will send email notifications whenever buildpack updates affect a deployed app.
+
+Restaging the apps rebuilds them with the new buildpack, enabling us to take advantage of whatever bugfixes or security updates are present in the new buildpack.
+
+There are two GitHub Actions that automate this process. Each are run manually and must be run once for each environment to enable testing any changes in staging before running within demo and production environments.
+
+When `notify-api-<env>`, `notify-admin-<env>`, `egress-proxy-notify-api-<env>`, and/or `egress-proxy-notify-admin-<env>` need to be restaged:
+
+1. Navigate to [the Restage apps GitHub Action](https://github.com/GSA/notifications-api/actions/workflows/restage-apps.yml)
+1. Click the `Run workflow` button to open a popup
+1. Leave `Use workflow from` on it's default of `Branch: main`
+1. Select the environment you need to restage from the dropdown
+1. Click `Run workflow` within the popup
+1. Repeat for other environments
+
+When `ssb-sms`, and/or `ssb-smtp` need to be restaged:
+
+1. Navigate to the [SSB Restage apps GitHub Action](https://github.com/GSA/usnotify-ssb/actions/workflows/restage-apps.yml)
+1. Click the `Run workflow` button to open a popup
+1. Leave `Use workflow from` on it's default of `Branch: main`
+1. Select the environment (either `staging` or `production`) you need to restage from the dropdown
+1. Click `Run workflow` within the popup
+1. Repeat for other environments
+
+When `ssb-devel-sms` and/or `ssb-devel-smtp` need to be restaged:
+
+1. Navigate to the [SSB Restage apps GitHub Action](https://github.com/GSA/usnotify-ssb/actions/workflows/restage-apps.yml)
+1. Click the `Run workflow` button to open a popup
+1. Leave `Use workflow from` on it's default of `Branch: main`
+1. Select the `development` environment from the dropdown
+1. Click `Run workflow` within the popup
+
+
+## <a name="smoke-testing"></a> Smoke-testing the App
+
+To ensure that notifications are passing through the application properly, the following steps can be taken to ensure all parts are operating correctly:
+
+1. Send yourself a password reset email. This will verify SES integration. The email can be deleted once received if you don't wish to change your password.
+1. Log into the app. This will verify SNS integration for a one-off message.
+1. Upload a CSV and schedule send for the soonest time after "Now". This will verify S3 connections as well as scheduler and worker processes are running properly.
+
+## <a name="cm"></a> Configuration Management
+
+Also known as: **How to move code from my machine to production**
+
+### Common Policies and Procedures
+
+1. All changes must be made in a feature branch and opened as a PR targetting the `main` branch.
+1. All PRs must be approved by another developer
+1. PRs to `main` and `production` branches must be merged by a someone with the `Administrator` role.
+1. PR documentation includes a Security Impact Analysis
+1. PRs that will impact the Security Posture must be approved by the US Notify ISSO.
+1. Any PRs waiting for approval should be talked about during daily Standup meetings.
+
+### notifications-api & notifications-admin
+
+1. Changes are deployed to the `staging` environment after a successful `checks.yml` run on `main` branch. Branch Protections prevent pushing directly to `main`
+1. Changes are deployed to the `demo` _and_ `production` environments after merging `main` into `production`. Branch Protections prevent pushing directly to `production`
+
+### usnotify-ssb
+
+1. Changes are deployed to `staging` and `production` environments after merging to the `main` branch. The `staging` deployment must be successful before `production` is attempted. Branch Protections prevent pushing directly to `main`
+
+### ttsnotify-brokerpak-sms
+
+1. A new release is created by pushing a tag to the repository on the `main` branch.
+1. To include the new version in released SSB code, create a PR in the `usnotify-ssb` repo updating the version in use in `app-setup-sms.sh`
+
+### datagov-brokerpak-smtp
+
+1. To include new verisons of the SMTP brokerpak in released SSB code, create a PR in the `usnotify-ssb` repo updating the version in use in `app-setup-smtp.sh`
+
+### Vulnerability Mitigation Changes
+
+US_Notify Administrators are responsible for ensuring that remediations for vulnerabilities are implemented. Response times vary based on the level of vulnerability as follows:
+
+* Critical (Very High) - 15 days
+* High - 30 days
+* Medium - 90 days
+* Low - 180 days
+* Informational - 365 days (depending on the analysis of the issue)
+
+## <a name="dns"></a> DNS Changes
+
+U.S. Notify DNS records are maintained within [the 18f/dns repository](https://github.com/18F/dns/blob/main/terraform/notify.gov.tf). To create new DNS records for notify.gov or any subdomains:
+
+1. Update the `notify.gov.tf` terraform to update or create the new records within Route53 and push the branch to the 18f/dns repository.
+1. Open a PR.
+1. Verify that the plan output within circleci creates the records that you expect.
+1. Request a PR review from the 18F/tts-tech-portfolio team
+1. Once the PR is approved and merged, verify that the apply step happened correctly within [CircleCI](https://app.circleci.com/pipelines/github/18F/dns)

+
+See [Infrastructure Overview](./infra-overview.md#request-new-phone-numbers) for information about SMS phone numbers in AWS.
+
+Once you have a number, it must be set in the app in one of two ways:
+
+* For the default phone number, to be used by Notify itself for OTP codes and the default from number for services, set the phone number as the `AWS_US_TOLL_FREE_NUMBER` ENV variable in the environment you are creating
+* For service-specific phone numbers, set the phone number in the Service's `Text message senders` in the settings tab.
+
+### Current Production Phone Numbers
+
+* +18447952263 - in use as default number. Notify's OTP messages and trial service messages are sent from this number
+* +18447891134 - to be used by Pilot Partner 1
+* +18888402596 - to be used by Pilot Partner 2

-# API Usage
-
-## Connecting to the API
-
-To make life easier, the [UK API client libraries](https://www.notifications.service.gov.uk/documentation) are compatible with Notify and the [UK API Documentation](https://docs.notifications.service.gov.uk/rest-api.html) is applicable.
-
-For a usage example, see [our Python demo](https://github.com/GSA/notify-python-demo).
-
-An API key can be created at https://HOSTNAME/services/YOUR_SERVICE_ID/api/keys. This is the same API key that is referenced as `USER_API_TOKEN` below.
-
-## Postman Documentation
-
-Internal-only  [documentation for exploring the API using Postman](https://docs.google.com/document/d/1S5c-LxuQLhAtZQKKsECmsllVGmBe34Z195sbRVEzUgw/edit#heading=h.134fqdup8d3m)
-
-
-## Using OpenAPI documentation
-
-An [OpenAPI](https://www.openapis.org/) specification [file](./openapi.yml) can be found at https://notify-staging.app.cloud.gov/docs/openapi.yml.
-
-See [writing-public-apis.md](./writing-public-apis.md) for links to tools to make it easier to use the OpenAPI spec within VSCode.
-
-### Retrieving a jwt-encoded bearer token for use
-
-On a mac, run:
-
-#### Admin UI token
-
-The admin UI token is required for any of the `internal-api` tagged methods. To create one and copy it to your pasteboard, run:
-
-```
-flask command create-admin-jwt | tail -n 1 | pbcopy
-```
-
-#### User token
-
-A user token is required for any of the `external-api` tagged methods. To create one and copy it to your pasteboard, run:
-
-```
-flask command create-user-jwt --token=<USER_API_TOKEN> | tail -n 1 | pbcopy
-```
-
-### Disable token expiration checking in development
-
-Because jwt tokens expire so quickly, the development server can be set to allow tokens older than 30 seconds:
-
-```
-env ALLOW_EXPIRED_API_TOKEN=1 make run-flask
-```

-# Database management
-
-## Initial state
-
-In Notify, several aspects of the system are loaded into the database via migration. This means that
-application setup requires loading and overwriting historical data in order to arrive at the current
-configuration.
-
-[Here are notes](https://docs.google.com/document/d/1ZgiUtJFvRBKBxB1ehiry2Dup0Q5iIwbdCU5spuqUFTo/edit#)
-about what is loaded into which tables, and some plans for how we might manage that in the future.
-
-Flask does not seem to have a great way to squash migrations, but rather wants you to recreate them
-from the DB structure. This means it's easy to recreate the tables, but hard to recreate the initial data.
-
-## Data Model Diagram
-
-A diagram of Notify's data model is available [in our compliance repo](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/data.logical.pdf).
-
-## Migrations
-
-Create a migration:
-
-```
-flask db migrate
-```
-
-Trim any auto-generated stuff down to what you want, and manually rename it to be in numerical order.
-We should only have one migration branch.
-
-Running migrations locally:
-
-```
-flask db upgrade
-```
-
-This should happen automatically on cloud.gov, but if you need to run a one-off migration for some reason:
-
-```
-cf run-task notifications-api-staging --commmand "flask db upgrade" --name db-upgrade
-```
-
-## Purging user data
-
-There is a Flask command to wipe user-created data (users, services, etc.).
-
-The command should stop itself if it's run in a production environment, but, you know, please don't run it
-in a production environment.
-
-Running locally: 
-
-```
-flask command purge_functional_test_data -u <functional tests user name prefix>
-```
-
-Running on cloud.gov:
-
-```
-cf run-task notify-api "flask command purge_functional_test_data -u <functional tests user name prefix>"
-```

-# Deploying
-
-We deploy automatically to cloud.gov for production, demo, and staging environments.
-
-Deployment to staging runs via the [base deployment action](../.github/workflows/deploy.yml) on GitHub, which pulls credentials from GitHub's secrets store in the staging environment.
-
-Deployment to demo runs via the [demo deployment action](../.github/workflows/deploy-demo.yml) on GitHub, which pulls credentials from GitHub's secrets store in the demo environment.
-
-Deployment to production runs via the [production deployment action](../.github/workflows/deploy-prod.yml) on GitHub, which pulls credentials from GitHub's secrets store in the production environment.
-
-The [action that we use](https://github.com/18F/cg-deploy-action) deploys using [a rolling strategy](https://docs.cloudfoundry.org/devguide/deploy-apps/rolling-deploy.html), so all deployments should have zero downtime.
-
-The API has 3 deployment environments:
-
-- Staging, which deploys from `main`
-- Demo, which deploys from `production`
-- Production, which deploys from `production`
-
-Configurations for these are located in [the `deploy-config` folder](../deploy-config/).
-
-In the event that a deployment includes a Terraform change, that change will run before any code is deployed to the environment. Each environment has its own Terraform GitHub Action to handle that change.
-
-Failures in any of these GitHub workflows will be surfaced in the Pull Request related to the code change, and in the case of `checks.yml` actively prevent the PR from being merged. Failure in the Terraform workflow will not actively prevent the PR from being merged, but reviewers should not approve a PR with a failing terraform plan.
-
-## Egress Proxy
-
-The API app runs in a [restricted egress space](https://cloud.gov/docs/management/space-egress/).
-This allows direct communication to cloud.gov-brokered services, but
-not to other APIs that we require.
-
-As part of the deploy, we create an
-[egress proxy application](https://github.com/GSA/cg-egress-proxy) that allows traffic out of our
-application to a select list of allowed domains.
-
-Update the allowed domains by updating `deploy-config/egress_proxy/notify-api-<env>.allow.acl`
-and deploying an updated version of the application throught he normal deploy process.
-
-## Sandbox environment
-
-There is a sandbox space, complete with terraform and `deploy-config/sandbox.yml` file available
-for experimenting with infrastructure changes without going through the full CI/CD cycle each time.
-
-Rules for use:
-
-1. Ensure that no other developer is using the environment, as there is nothing stopping changes from overwriting each other.
-1. Clean up when you are done:
-    - `terraform destroy` from within the `terraform/sandbox` directory will take care of the provisioned services
-    - Delete the apps and routes shown in `cf apps` by running `cf delete APP_NAME -r`
-    - Delete the space deployer you created by following the instructions within `terraform/sandbox/secrets.auto.tfvars`
-
-### Deploying to the sandbox
-
-1. Set up services:
-    ```
-    $ cd terraform/sandbox
-    $ ../create_service_account.sh -s notify-sandbox -u <your-name>-terraform -m > secrets.auto.tfvars
-    $ terraform init
-    $ terraform plan
-    $ terraform apply
-    ```
-1. start a pipenv shell as a shortcut to load `.env` file variables: `$ pipenv shell`
-1. Output requirements.txt file: `pipenv requirements > requirements.txt`
-1. Deploy the application:
-  ```
-  cf push --vars-file deploy-config/sandbox.yml --var NEW_RELIC_LICENSE_KEY=$NEW_RELIC_LICENSE_KEY
-  ```

-# Infrastructure overview
-
-A diagram of the system is available [in our compliance repo](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/application.boundary.png).
-
-Notify is a Flask application running on [cloud.gov](https://cloud.gov), which also brokers access to a PostgreSQL database and Redis store.
-
-In addition to the Flask app, Notify uses Celery to manage the task queue. Celery stores tasks in Redis.
-
-## GitHub Repositories
-
-Application, infrastructure, and compliance work is spread across several repositories:
-
-### Application
-
-* [notifications-api](https://github.com/GSA/notifications-api) for the API app
-* [notifications-admin](https://github.com/GSA/notifications-admin) for the Admin UI app
-* [notifications-utils](https://github.com/GSA/notifications-utils) for common library functions
-
-### Infrastructure
-
-In addition to terraform directories in the api and admin apps above:
-
-#### We maintain:
-
-* [usnotify-ssb](https://github.com/GSA/usnotify-ssb) A supplemental service broker that provisions SES and SNS for us
-* [ttsnotify-brokerpak-sms](https://github.com/GSA/ttsnotify-brokerpak-sms) The brokerpak defining SNS (SMS sending)
-
-#### We use:
-
-* [datagov-brokerpak-smtp](https://github.com/GSA-TTS/datagov-brokerpak-smtp) The brokerpak defining SES
-* [cg-egress-proxy](https://github.com/GSA-TTS/cg-egress-proxy/) The caddy proxy that allows external API calls
-
-### Compliance
-
-* [us-notify-compliance](https://github.com/GSA/us-notify-compliance) for OSCAL control documentation and diagrams
-
-## Terraform
-
-### Development
-
-There are several remote services required for local development:
-
-* s3
-* ses
-* sns
-
-Credentials for these services are created by running:
-
-1. `cd terraform/development`
-1. `./run.sh`
-
-in both the api repository as well as the admin repository.
-
-This will append credentials to your `.env` file. You will need to manually clean up any prior runs from that file if you run that command again.
-
-You can remove your development infrastructure by running `./run.sh -d`
-
-#### Resetting
-
-`./reset.sh` can be used to import your development infrastructure information in case of a new computer or new working tree and the old terraform state file was not transferred.
-
-#### Offboarding
-
-`./reset.sh -u USER_TO_OFFBOARD` can be used to import another user's development resources in order to clean them up. Steps for use:
-
-1. Move your existing terraform state file aside temporarily, so it is not overwritten.
-1. `./reset.sh -u USER_TO_OFFBOARD`
-1. Answer no to the prompt about creating missing resources.
-1. Run `./run.sh -u USER_TO_OFFBOARD -d` to fully remove the rest of that user's resources.
-
-### Cloud.gov
-
-The cloud.gov environment is configured with Terraform. See [the `terraform` folder](../terraform/) to learn about that.
-
-## AWS
-
-In addition to services provisioned through cloud.gov, we have several services provisioned via [supplemental service brokers](https://github.com/GSA/usnotify-ssb) in AWS. Our AWS services are currently located in [several regions](https://github.com/GSA/usnotify-ssb#aws-accounts-and-regions-in-use) using Studio-controlled AWS accounts.
-
-To send messages, we use Amazon Web Services SNS and SES. In addition, we use AWS Pinpoint to provision and manage phone numbers, short codes, and long codes for sending SMS.
-
-In SNS, we have 3 topics for SMS receipts. These are not currently functional, so senders won't know the status of messages.
-
-Through Pinpoint, the API needs at least one number so that the application itself can send SMS for authentication codes.
-
-The API also has access to AWS S3 buckets for storing CSVs of messages and contact lists. It does not access a third S3 bucket that stores agency logos.
-
-## New Relic
-
-We are using [New Relic](https://one.newrelic.com/nr1-core?account=3389907) for application monitoring and error reporting. When requesting access to New Relic, ask to be added to the Benefits-Studio subaccount.
-
-## Onboarding
-
-- [ ] Join [the GSA GitHub org](https://github.com/GSA/GitHub-Administration#join-the-gsa-organization)
-- [ ] Get permissions for the repos
-- [ ] Get access to the cloud.gov org && spaces
-- [ ] Get [access to AWS](https://handbook.tts.gsa.gov/launching-software/infrastructure/#cloud-service-provider-csp-sandbox-accounts), if necessary
-- [ ] Get [access to New Relic](https://handbook.tts.gsa.gov/tools/new-relic/#how-do-i-get-access-to-new-relic), if necessary
-- [ ] Create the local `.env` file by copying `sample.env` and running `./run.sh` within the `terraform/development` folder
-- [ ] Do stuff!
-
-## Setting up the infrastructure
-
-These steps are required for new cloud.gov environments. Local development borrows SES & SNS infrastructure from the `notify-staging` cloud.gov space, so these steps are not required for new developers.
-
-### Steps to do a clean prod deploy to cloud.gov
-
-Steps for deploying production from scratch. These can be updated for a new cloud.gov environment by subbing out `prod` or `production` for your desired environment within the steps.
-
-1. Deploy API app
-    1. Update `terraform-production.yml` and `deploy-prod.yml` to point to the correct space and git branch.
-    1. Ensure that the `domain` module is commented out in `terraform/production/main.tf`
-    1. Run CI/CD pipeline on the `production` branch by opening a PR from `main` to `production`
-    1. Create any necessary DNS records (check `notify-api-ses-production` service credentials for instructions) within https://github.com/18f/dns
-    1. Follow the `Steps to prepare SES` below
-    1. (Optional) if using a public API route, uncomment the `domain` module and re-trigger a deploy
-1. Deploy Admin app
-    1. Update `terraform-production.yml` and `deploy-prod.yml` to point to the correct space and git branch.
-    1. Ensure that the `api_network_route` and `domain` modules are commented out in `terraform/production/main.tf`
-    1. Run CI/CD pipeline on the `production` branch by opening a PR from `main` to `production`
-    1. Uncomment the `api_network_route` and `domain` modules and re-trigger a deploy
-    1. Create DNS records for `domain` module within https://github.com/18f/dns
-
-### Steps to prepare SES
-
-1. After the first deploy of the application with the SSB-brokered SES service completes:
-    1. Log into the SES console and navigate to the SNS subscription page.
-    1. Select "Request confirmation" for any subscriptions still in "Pending Confirmation" state
-1. Find and replace instances in the repo of "testsender", "testreceiver" and "dispostable.com", with your origin and destination email addresses, which you verified in step 1 above.
-
-TODO: create env vars for these origin and destination email addresses for the root service, and create new migrations to update postgres seed fixtures
-
-### Steps to prepare SNS
-
-#### Move SNS out of sandbox.
-
-This should be complete for all regions U.S. Notify has been deployed to or is currently planned to be deployed to.
-
-1. Visit the SNS console for the region you will be sending from. Notes:
-    1. SNS settings are per-region, so each environment must have its own region
-    1. Pinpoint and SNS have confusing regional availability, so ensure both are available before submitting any requests.
-1. Choose `Text messaging (SMS)` from the sidebar
-1. Click the `Exit SMS Sandbox` button and submit the support request. This request should take at most a day to complete. Be sure to request a higher sending limit at the same time.
-
-#### Request new phone numbers
-
-1. Go to Pinpoint console for the same region you are using SNS in.
-1. In the lefthand sidebar, go the `SMS and Voice` (bottom) and choose `Phone Numbers`
-1. Under `Number Settings` choose `Request Phone Number`
-1. Choose Toll-free number, tick SMS, untick Voice, choose `transactional`, hit next and then `request`
-1. Select `Toll-free registrations` and `Create registration`
-1. Select the number you just created and then `Register existing toll-free number`
-1. Complete and submit the form. Approval usually takes about 2 weeks.
-1. See the [run book](./run-book.md) for information on how to set those numbers.

-# How messages are queued and sent
-
-There are several ways for notifications to come into the API.
-
-- Messages sent through the API enter through `app/notifications/post_notifications.py`
-- One-off messages sent from the UI enter through `create_one_off_notification` in `app/service/rest.py`
-- CSV uploads enter through `app/job/rest.py`
-
-API messages and one-off UI messages come in one at a time, and take slightly-separate routes
-that both end up at `persist_notification`, which writes to the database, and `provider_tasks.deliver_sms`,
-which enqueues the sending.
-
-For CSV uploads, the CSV is first stored in S3 and queued as a `Job`. When the job runs, it iterates
-through the rows, running `process_job.save_sms` to send notifications through `persist_notification` and 
-`provider_tasks.deliver_sms`.

-# Queues and tasks
-
-The API puts tasks into Celery queues for dispatch.
-
-There are a bunch of queues:
-- priority tasks
-- database tasks
-- send sms tasks
-- send email tasks
-- research mode tasks
-- reporting tasks
-- job tasks
-- retry tasks
-- notify internal tasks
-- service callbacks
-- service callbacks retry
-- letter tasks
-- sms callbacks
-- antivirus tasks
-- save api email tasks
-- save api sms tasks
-
-And these tasks:
-- check for missing rows in completed jobs
-- check for services with high failure rates or sending to tv numbers
-- check if letters still in created
-- check if letters still pending virus check
-- check job status
-- create fake letter response file
-- create nightly billing
-- create nightly billing for day
-- create nightly notification status
-- create nightly notification status for service and day
-- delete email notifications
-- delete inbound sms
-- delete invitations
-- delete letter notifications
-- delete notifications for service and type
-- delete notifications older than retention
-- delete sms notifications
-- delete verify codes
-- deliver email
-- deliver sms
-- process incomplete jobs
-- process job
-- process returned letters list
-- process ses result
-- process virus scan error
-- process virus scan failed
-- raise alert if letter notifications still sending
-- raise alert if no letter ack file
-- record daily sorted counts
-- remove letter jobs
-- remove sms email jobs
-- replay created notifications
-- run scheduled jobs
-- save api email
-- save api sms
-- save daily notification processing time
-- save email
-- save letter
-- save sms
-- send complaint
-- send delivery status
-- send inbound sms
-- switch current sms provider on slow delivery
-- tend providers back to middle
-- timeout sending notifications
-- update billable units for letter
-- update letter notifications statuses
-- update letter notifications to error
-- update letter notifications to sent
-- update validation failed for templated letter
-
-## Priority queue
-
-For tasks that should happen before other stuff, there's a priority queue. Platform admins
-can set templates to use this queue.
-
-Currently, this queue doesn't do anything special. If the normal queue is very busy, it's
-possible that this queue will be faster merely because it's shorter. By the same logic, a 
-busy priority queue is likely to be _slower_ than the normal queue
-
-## Celery scheduled tasks
-
-After scheduling some tasks, run celery beat to get them moving:
-
-```
-make run-celery-beat
-```

-* the various `*_history` tables
-
-
-## <a name="restaging-apps"></a> Restaging Apps
-
-Our apps must be restaged whenever cloud.gov releases updates to buildpacks. Cloud.gov will send email notifications whenever buildpack updates affect a deployed app.
-
-Restaging the apps rebuilds them with the new buildpack, enabling us to take advantage of whatever bugfixes or security updates are present in the new buildpack.
-
-There are two GitHub Actions that automate this process. Each are run manually and must be run once for each environment to enable testing any changes in staging before running within demo and production environments.
-
-When `notify-api-<env>`, `notify-admin-<env>`, `egress-proxy-notify-api-<env>`, and/or `egress-proxy-notify-admin-<env>` need to be restaged:
-
-1. Navigate to [the Restage apps GitHub Action](https://github.com/GSA/notifications-api/actions/workflows/restage-apps.yml)
-1. Click the `Run workflow` button to open a popup
-1. Leave `Use workflow from` on it's default of `Branch: main`
-1. Select the environment you need to restage from the dropdown
-1. Click `Run workflow` within the popup
-1. Repeat for other environments
-
-When `ssb-sms`, and/or `ssb-smtp` need to be restaged:
-
-1. Navigate to the [SSB Restage apps GitHub Action](https://github.com/GSA/usnotify-ssb/actions/workflows/restage-apps.yml)

-## <a name="smoke-testing"></a> Smoke-testing the App
-
-To ensure that notifications are passing through the application properly, the following steps can be taken to ensure all parts are operating correctly:
-
-1. Send yourself a password reset email. This will verify SES integration. The email can be deleted once received if you don't wish to change your password.
-1. Log into the app. This will verify SNS integration for a one-off message.
-1. Upload a CSV and schedule send for the soonest time after "Now". This will verify S3 connections as well as scheduler and worker processes are running properly.

-
-See [Infrastructure Overview](./infra-overview.md#request-new-phone-numbers) for information about SMS phone numbers in AWS.
-
-Once you have a number, it must be set in the app in one of two ways:
-
-* For the default phone number, to be used by Notify itself for OTP codes and the default from number for services, set the phone number as the `AWS_US_TOLL_FREE_NUMBER` ENV variable in the environment you are creating
-* For service-specific phone numbers, set the phone number in the Service's `Text message senders` in the settings tab.
-
-### Current Production Phone Numbers

-US Notify
-=========
-
-System Description
-------------------
-
-US Notify is a service being developed by the TTS Public Benefits Studio to increase the availability of
-SMS and email notifications to Federal, State, and Local Benefits agencies.
-
-Agencies that sign up will be able to create and use personalized message templates for sending
-notifications to members of the public regarding their benefits. These could include reminders
-about upcoming enrollment deadlines and tasks, or information about upcoming appointments, events,
-or services.
-
-The templates are sent by the agency using one of two methods:
-
-* using the US Notify API to send a message to a given recipient with given personalization values
-* using the US Notify website to upload a CSV file of recipients and their personalization values, one row per message
-
-### Environment
-
-US Notify is comprised of two applications both running on cloud.gov:
-
-* Admin, a Flask website running on the python_buildpack which hosts agency user-facing UI
-* API, a Flask application running on the python_buildpack hosting the US Notify API
-
-US Notify utilizes several cloud.gov-provided services:
-
-* S3 buckets for temporary file storage
-* Elasticache (redis) for cacheing data and enqueueing background tasks
-* RDS (PostgreSQL) for system data storage
-
-US Notify also provisions and uses two AWS services via a [supplemental service broker](https://github.com/GSA/usnotify-ssb):
-
-* [SNS](https://aws.amazon.com/sns/) for sending SMS messages
-* [SES](https://aws.amazon.com/ses/) for sending email messages
-
-For further details of the system and how it connects to supporting services, see the [application boundary diagram](https://github.com/GSA/us-notify-compliance/blob/main/diagrams/rendered/apps/application.boundary.png)

-# Testing
-
-```
-# install dependencies, etc.
-make bootstrap
-
-make test
-```
-
-This will run:
-- flake8 for code styling
-- isort for import styling
-- pytest for the test suite
-
-On GitHub, in addition to these tests, we run:
-- bandit for code security
-- pip-audit for dependency vulnerabilities
-- OWASP for dynamic scanning
-
-## CI testing
-
-We're using GitHub Actions. See [/.github](../.github/) for the configuration.
-
-In addition to commit-triggered scans, the `daily_checks.yml` workflow runs the relevant dependency audits, static scan, and/or dynamic scans at 10am UTC each day. Developers will be notified of failures in daily scans by GitHub notifications.
-
-### Nightly Scans
-
-Within GitHub Actions, several scans take place every day to ensure security and compliance.
-
-
-#### [daily-checks.yml](../.github/workflows/daily_checks.yml)
-
-`daily-checks.yml` runs `pip-audit`, `bandit`, and `owasp` scans to ensure that any newly found vulnerabilities do not impact notify. Failures should be addressed quickly as they will also block the next attempted deploy.
-
-#### [drift.yml](../.github/workflows/drift.yml)
-
-`drift.yml` checks the deployed infrastructure against the expected configuration. A failure here is a flag to check audit logs for unexpected access and/or behavior and potentially destroy and re-deploy the application. Destruction and redeployment of all underlying infrastructure is an extreme remediation, and should only be attempted after ensuring that a good database backup is in hand.
-
-## Manual testing
-
-If you're checking out the system locally, you may want to create a user quickly.
-
-`pipenv run flask command create-test-user`
-
-This will run an interactive prompt to create a user, and then mark that user as active. *Use a real mobile number* if you want to log in, as the SMS auth code will be sent here.
-
-## To run a local OWASP scan
-
-1. Run `make run-flask` from within the dev container.
-2. On your host machine run:
-
-```
-docker run -v $(pwd):/zap/wrk/:rw --network="notify-network" -t owasp/zap2docker-weekly zap-api-scan.py -t http://dev:6011/docs/openapi.yml -f openapi -c zap.conf
-```
-
-The equivalent command if you are running the API locally:
-
-```
-docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-weekly zap-api-scan.py -t http://host.docker.internal:6011/docs/openapi.yml -f openapi -c zap.conf -r report.html

-# Writing public APIs
-
-_Most of the API endpoints in this repo are for internal use. These are all defined within top-level folders under `app/` and tend to have the structure `app/<feature>/rest.py`._
-
-## Overview
-
-Public APIs are intended for use by services and are all located under `app/v2/` to distinguish them from internal endpoints. Originally we did have a "v1" public API, where we tried to reuse / expose existing internal endpoints. The needs for public APIs are sufficiently different that we decided to separate them out. Any "v1" endpoints that remain are now purely internal and no longer exposed to services.
-
-## Documenting APIs
-
-New and existing APIs should be documented within [openapi.yml](./openapi.yml). Tools to help
-with editing this file:
-
-* [OpenAPI Editor for VSCode](https://marketplace.visualstudio.com/items?itemName=42Crunch.vscode-openapi)
-* [OpenAPI specification](https://spec.openapis.org/oas/v3.0.2)
-
-
-## New APIs
-
-Here are some pointers for how we write public API endpoints.
-
-### Each endpoint should be in its own file in a feature folder
-
-Example: `app/v2/inbound_sms/get_inbound_sms.py`
-
-This helps keep the file size manageable but does mean a bit more work to register each endpoint if we have many that are related. Note that internal endpoints are grouped differently: in large `rest.py` files.
-
-### Each group of endpoints should have an `__init__.py` file
-
-Example:
-
-```
-from flask import Blueprint
-
-from app.v2.errors import register_errors
-
-v2_notification_blueprint = Blueprint("v2_notifications", __name__, url_prefix='/v2/notifications')
-
-register_errors(v2_notification_blueprint)
-```
-
-Note that the error handling setup by `register_errors` (defined in [`app/v2/errors.py`](../app/v2/errors.py)) for public API endpoints is different to that for internal endpoints (defined in [`app/errors.py`](../app/errors.py)).
-
-### Each endpoint should have an adapter in each API client
-
-Example: [Ruby Client adapter to get template by ID](https://github.com/alphagov/notifications-ruby-client/blob/d82c85452753b97e8f0d0308c2262023d75d0412/lib/notifications/client.rb#L110-L115).
-
-All our clients should fully support all of our public APIs.
-
-Each adapter should be documented in each client ([example](https://github.com/alphagov/notifications-ruby-client/blob/d82c85452753b97e8f0d0308c2262023d75d0412/DOCUMENTATION.md#get-a-template-by-id)). We should also document each public API endpoint in our generic API docs ([example](https://github.com/alphagov/notifications-tech-docs/blob/2700f1164f9d644c87e4c72ad7223952288e8a83/source/documentation/_api_docs.md#send-a-text-message)). Note that internal endpoints are not documented anywhere.
-
-### Each endpoint should specify the authentication it requires
-
-This is done as part of registering the blueprint in `app/__init__.py` e.g.
-
-```
-post_letter.before_request(requires_auth)
-application.register_blueprint(post_letter)
-```
