    <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>

    <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">Integrate directly with the API</h2>
    <p>If you cannot use the client libraries, you can integrate directly with the API instead.</p>
    <p>Read the REST API documentation.</p>
