Request access

Email hmpps-external-api@justice.gov.uk to request access to this API and Events.

All requests will be manually approved.

If approved you will be granted a specific role that defines which API endpoints you have access to, and what data is included in the responses.

All roles provide access to a /status endpoint that can be used to verify connectivity and authentication.

You may also request access to our non-live environment for testing purposes.

You will receive access credentials including:

  1. API Key
  2. Client Certificate

For information on how to use these credentials, see our Authentication section.

Please review the available endpoints, and let us know what data you require when you get in contact. We provide API access on an endpoint by endpoint basis. You might not receive access to all the endpoints you request.

Please contact us at hmpps-external-api@justice.gov.uk to get a better understanding of what access we are likely to provide.
