Hi Nick, In the case of Authzed, we provide a gRPC API [0] which can be used from any application or language that supports gRPC, as well as designed client libraries for specific languages [1] to make integration even easier. Applications primarily integrate by making Check requests [2] at any point in which a protected resource is being accessed and Write requests [3] at any point in which permissions are granted or removed.
