# Client libraries

GC Notify (opens new window) was based on the UK government's notification system. Therefore, the API is also available using the clients developed by GOV.UK (opens new window).

# Before integrating the API

You will need to change the API endpoint when creating a client.

Feature differences to keep in mind

  • Sending files by email is different with GC Notify
  • Sending bulk notifications through the GOV.UK Notify clients is not directly supported. You can still use one if the client supports customization of the URL endpoint
  • Sending letters is not available
  • Receiving text messages is not available
