This documentation is for developers who want to integrate the GOV.UK Notify API with a web application or back office system.

Client libraries

Links to documentation open in a new tab.

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.

Integrate directly with the API

If you cannot use the client libraries, you can integrate directly with the API instead.
