The Protection API provides a UMA-compliant set of endpoints providing:
With this endpoint, resource servers can manage their resources remotely and enable policy enforcers to query the server for the resources that need protection.
In the UMA protocol, resource servers access this endpoint, which issues permission tickets.
An important requirement for this API is that only resource servers are allowed to access its endpoints using a special OAuth2 access token called a protection API token (PAT). In UMA, a PAT is a token with the scope uma_protection.
