Power Platform - Information regarding the end of support for Global Discovery Service (GDS) API

🚨 The Signal: Microsoft is deprecating the legacy Global Discovery Service (GDS) API for Power Platform on September 21, 2026. Applications using GDS for Dataverse organization discovery must migrate to the Power Platform List Environments API to maintain functionality and security.

The Impact

Developers and security teams are affected by the need to update applications and authentication, posing a risk of service disruption if not addressed.

• Developers: Must rewrite API calls and update authentication.
• Security Teams: Need to validate updated application permissions in Entra ID.
• Application Owners: Risk of application downtime if updates are not completed.
• Compliance Teams: Potential for non-compliance if critical systems become unavailable.

The Action

1. Identify all applications and scripts calling globaldisco.crm.dynamics.com REST API endpoints.
2. Update identified applications to use the Power Platform List Environments API.
3. Modify application authentication to request tokens with scope 'https://api.powerplatform.com/.default'.
4. Register the Power Platform API (app ID 8578e004-a5c6-46e7-913e-12f58912df43) as an API permission in relevant Microsoft Entra app registrations.
5. Thoroughly test all updated integrations to ensure compatibility and functionality.
