When the user performs an app or game-defined transaction, your server instructs the client-side code to invoke the Play Integrity API request with its ID. The Play server returns an encrypted response containing that ID along with an integrity verdict. Your app then forwards that response to your server for verification. Your server can decide what your app or game should do next.
