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

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}) 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? Identify any applications or scripts that call globaldisco.crm.dynamics.com REST API endpoints. Update your applications to use the Power Platform List Environments API instead of the GDS endpoints. Test your updated integrations against the new endpoints to verify compatibility. https://api.powerplatform.com/.default8578e004-a5c6-46e7-913e-12f58912df43Power 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. Message ID: MC1474128
