Building and customizing solutions using Microsoft 365 Copilot APIs and tools
Per Agent Cost
I am suddenly getting a 403 Forbidden error when using the /resources version of the Copilot Studio (MCS) licensing endpoint.
Failing Endpoint (Returns 403):
Working Endpoints (Returns 200 OK):
Using the exact same token and admin permissions, the base endpoints work completely fine:
GET https://api.powerplatform.com/licensing/entitlements/MCSMessages?api-version=2024-10-01
GET {{ppHost}}/licensing/environments/entitlements/MCSMessages?searchRequest=&api-version=1
Because our token and permissions are valid (proven by the working endpoints above), why is the /resources route suddenly blocking us with a 403 error? Has access to this specific path changed?
