My logic is when merchant purchase the credits I am storing those amount on behalf of shop and it can be deducted when merchant uses my services. What to do if merchant uninstall my app and reinstall it?
Should I remove the credits of the merchant to 0? Right now, I am keeping them as it. Because, when the app reinstall so the remaining credits should be there?
Kindly guide me about the flow of application recharge Billing API.
