403 Permission Error When Updating a Claude User's Role via Admin365
Error:
Your API key does not have permission to use the specified resource.
What it means: The account or Admin API key changing the role is not an organization Admin or Owner. Only Admins and Owners can update member roles.
Solution: Run the role change from an Owner or Admin account. If you use an Admin API key, confirm an Owner or Admin created it, then resend the request.
