Connect to the MSA metadata

To integrate GOV.UK Verify into your service, you need to connect your service provider to the Matching Service Adapter (MSA) metadata.

The MSA metadata:

  • indicates the URL where your service will send users with their authentication requests - this is the GOV.UK Verify hub

  • lists one or more MSA signing certificates, so your service can validate messages that are sent by your MSA

  • describes the MSA as an identity provider

The MSA metadata is located in your MSA at /matching-service/SAML2/metadata

Your service must poll the MSA metadata every 10 minutes.
