Hi guys!
My product is a mobile game with IAP available in Google Play and App Store.
When user commit purchase we verify his payment via google (in terms if it is google play of course) and than send this purchase as validated with reciept and all other data to our data base and also to Amplitude.
Sometimes users asks for chargeback and Google Play refund their payment.
In this case we already have their payments in our Amplitude, but this payments are actually refunded and they shouldnt be counted in our revenue dashboards and revenue-based metrics.
How do you guys usually deal with such case (taking into considiration that we cant change data which were already written in AMPL) ?
