  <h1 class="heading-large">Documentation</h1>
    <p>This documentation is for developers who want to integrate the GOV.UK Notify API with a web application or back office system.</p>
  <h2 class="heading-medium">Client libraries</h2>
    <p>Links to documentation open in a new tab.</p>
  <ul class="list list-bullet">
    {% for key, label in [
      ('java', 'Java'),
      ('net', '.NET'),
      ('node', 'Node JS'),
      ('php', 'PHP'),
      ('python', 'Python'),

  </ul>
    <p>A developer should be able to set up the API client and start sending test messages in around 30 minutes. A full integration can take a few days, depending on the other systems you’re using.</p>
  <h2 class="heading-medium">Integrating directly with the API</h2>
    <p>We recommend using the client libraries rather than integrating directly with the API.</p>
    <p>There’s no documentation for using the API in this way. You’ll still need to read the client documentation to understand:</p>
  <ul class="list list-bullet">
    <li>what the API client does</li>
    <li>what development work you’ll need to do</li>
  </ul>
  <p>To send a message you’ll need to create an HTTPS request and add an authorisation header with your API key. The API key is encoded with JSON Web Tokens (JWT).</p>
