in-app-purchase

问题 I'm having trouble figuring out how to detect when a refund has been issued for a managed (uncomsumable) in-app product in Android using com.android.billingclient:billing:2.0.3 . The problem seems fairly deep though maybe I'm making it more complicated than it ought to be. To begin, I've made a test purchase which has been acknowledged AND refunded: Looking at the logs of my app I see the following: D/BillingManager: Got a verified purchase: Purchase. Json: {"orderId":"GPA.3362-7185-5389

问题 Is it possible to know is subscription was purchased as free trial? For now I can't find a way how to do it on server/device side.

问题 I have a macOS app with auto-renewable subscription IAP and I want to add a free trial period. I'm trying to use app store "introductory offer" feature, but can't figure out how to get it working. I have configured a free trial introductory offer in itunes connect, but nothing changes when I try to buy the subscription from my app. So my question is: Do I have to support this feature in my app's code (as described here https://developer.apple.com/documentation/storekit/in-app_purchase

问题 I am working with the Inapp purchases in my current app. After successfull purchase i save the "receipt" of the product on my server.

问题 Our iOS app uses in-app purchases, both one-time and an auto-renewing subscription. Both these are non-consumable. iOS offers two APIs: refresh receipt, and restore completed transactions. It seems that the latter works for all cases, while the former works in only some cases. Specifically, when we restore an auto-renewable purchase to a new device, restore purchased transactions will cause future renewals to generate a transaction that will be sent in the background to the new device, where
