From this endpoint resource servers can manage their resources remotely and enable link::../../../../enforcer/overview.adoc[Policy Enforcers] to query the server for the resources that need protection.
An important requirement for this API is that _only_ resource servers are supposed to access its endpoints using a special OAuth2 access token called *Protection API Token* or *PAT*.
In UMA, a PAT is just a token with a scope *uma_protection*.
