How to detect refund?

[kewitschka]

How do I know if a purchase was refunded? Is it sufficient to use billingConnector.isPurchased() and in case of a refund it returns false?

using a test account I purchased the product and from the Play Store console I refunded with removed entitlement but somehow it's still showing onPurchasedProductsFetched

The result of my research is that it is not possible with Google's IAP library. The only reliable way is to use the Voided Purchases API, which requires a server: https://developers.google.com/android-publisher/voided-purchases?hl=en

I have 5 Non-consumeable items
Before onPurchasedProductsFetched I call my function to reset purchases which is removing all shared prefs
and when onPurchasedProductsFetched I re-enable all the purchased products Obviously, I check for an internet connection to ensure that I don't reset purchases without being able to get the purchased products again.

This way If I refund the product from the console I was able to reset it because the product will not be fetched and No preference will be saved
