The Play Integrity API is used to verify that your app is a Genuine App Binary that has not been modified compared to what is available on the Play Store. It validates that the current user account is licensed (the user that installed or paid for your app) and whether the app is free from known malware.
This plugin calls the Play Integrity API requestIntegrityToken method which returns a token that your App's server must verify with Google Play Servers.
The call requestIntegrityToken will return a token on success which you must send to your backend for verification. See Google's Docs on this.
