Why this score?

HIGH
Enough detail is available to trust this assessment.
Assessment Reasoning
Deprecated GDS endpoints will be removed in three days causing any scripts or applications using them to fail. Admins and developers need to identify dependencies, update API calls to the Power Platform List Environments API, and revise authentication scopes and permissions. The short timeline makes this highly urgent and involves integration changes, testing, and configuration, though user-facing impact is indirect and minimal.

📢 Official Microsoft Message Center Announcement

Power Platform – Information regarding the end of support for Global Discovery Service (GDS) API
Message ID: MC1474128
On September 21, 2026, the Global Discovery Service (GDS) API will have reached end of support.

How does this affect me?
The legacy Global Discovery Service (GDS) REST API endpoints hosted at globaldisco.crm.dynamics.com will no longer be available.

Deprecated GDS endpoints:
  • https://globaldisco.crm.dynamics.com/api/discovery/v1.0/Instances
  • https://globaldisco.crm.dynamics.com/api/discovery/v2.0/Instances
  • https://globaldisco.crm.dynamics.com/api/discovery/v1.0/Instances({id})
This change impacts listing and retrieval of Dataverse organizations. There is no impact to service performance or availability for your environment(s)

Please note that this end of support change excludes the Dataverse Developer Tools such as CRM SDK and Connectors.

What action do I need to take?
  1. Identify any applications or scripts that call globaldisco.crm.dynamics.com REST API endpoints.
  2. Update your applications to use the Power Platform List Environments API instead of the GDS endpoints.
  3. Test your updated integrations against the new endpoints to verify compatibility.
Please note that the Power Platform API uses a different token audience than GDS. You will need to update your authentication to request tokens with the scope (https://api.powerplatform.com/.default) and register the Power Platform API (app ID 8578e004-a5c6-46e7-913e-12f58912df43) as an API permission in your Microsoft Entra app registration. For detailed setup instructions, see Power Platform API Authentication.

To avoid a disruption in service, please migrate to the Power Platform List Environments API before September 21, 2026.

If you need additional assistance, please contact Microsoft Support.
