如何使用Google BillingClient库检测退款 [英] How to detect refund with google billingclient library

问题描述

我想知道如何检测退款或任何类型的应用内购买取消(不是订阅，也不是消耗品).

I was wondering how to detect a refund, or any type of cancelation of an in-app purchase(not a subscription and not a consumable).

我目前正在测试，当我在Google退还测试费用时:

I'm currently making my test and when I refund a test in google like that :

该购买仍然存在于billingClient.queryPurchaseHistoryAsync()(甚至在queryPurchase()中).

The purchase is still present in billingClient.queryPurchaseHistoryAsync() (even in queryPurchase()).

如何检测到此类更改以及如何为退款用户禁用我的应用?

How can I detect such changes and how can I disable my app for refunded users?

谢谢.

推荐答案

我确实了解您对退款项目的担心.

I do understand your concern regarding refunded items.

如果您提供应用内商品，则可以使用无效购买API 请求您的应用内商品的无效购买清单.当用户要求退款以进行应用内购买时，您可以查看已购买的商品并从该用户那里取回已退款的数字商品.

If you offer in-app products, you can use the Voided Purchases API to request a list of voided purchases for your in-app products. When a user requests a refund for in-app purchases, you can see what was purchased and take back the refunded digital goods from that user.

为保护您的应用程序免遭退款滥用，请使用保护您的应用程序退款滥用帮助指南中的内容，以获取保护应用内应用产品的最佳做法.
