I am suddenly getting a 403 Forbidden error when using the /resources version of the Copilot Studio (MCS) licensing endpoint.

Failing Endpoint (Returns 403):

GET https://api.powerplatform.com/licensing/entitlements/MCSMessages/resources?fromDate=2026-11-03&toDate=...&api-version=2024-10-01

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

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?

    Hello aryane sadh

    Welcome to Microsoft Q&A forum.

    This could mean that there was a deprecated tenant-wide API operation that is now returning 403, rather than evidence that your existing token has become invalid. Also, I can find no evidence of the access path has changed.

    However, I want to make sure first. There was an outage around yesterday that affects many Microsoft Services, which including Copilot, can you please check again first to see if it is related?

    I'm waiting for your reply.
