Rewarded advertising How can the server make sure that the user has viewed the ad?

Question

Android

There is a small application for android. There is a function of viewing ads for a reward. I can track the event when an ad is viewed in the application, but if a request is sent from the application to the server (To accrue coins to the user), then such a request can be easily caught by a sniffer and called without viewing ads. Is it possible to somehow get a notification about the viewed ad to the server?

Answer 1

protect the request with a one-time token
