PeerAuthenticator (endpoints-framework 2.0.0-beta.5 API)

public interface PeerAuthenticator

Peer authenticators aim to verify the peer and run before Authenticator. It returns false if authentication failed and stops handling the rest of the request; true if authentication succeeds and continue to execute rest of peer authenticators.

If no peer authenticator is set, EndpointsPeerAuthenticator will be the default to verify the request is from Google. If you supply your own peer authenticator, make sure you also put EndpointsPeerAuthenticator to the head of peerAuthenticators list to verify the request is from Google.
