如何检测 Google 应用内结算的取消或退款订单？

Question

I have red a lot of posts and Google documents, but am still not clear how to tell an in-app purchase has been refunded. I have red carefully In-App Billing v3 - Don't detect refund and Does Google Play In-App Billing Version 3 support refunds? .

I believe that I took the following notes from an official Google document a while ago by copy & paste:

purchaseState: The purchase state of the order. Possible values are 0 (purchased), 1 (canceled), or 2 (refunded).

Now, the official document has the following:

-> purchaseState: The purchase state of the order. It always returns 0-

(purchased).

More specifically, if an IAB purchase is refunded or canceled, is that still in the user's inventory obtained by mHelper.queryInventoryAsync(mGotInventoryListener)? If so, how can one tell the purchase has been canceled or refunded?

Update [2019-12-12]:

I have tested many times and confirmed the following:

If an order is canceled after refunding, it will disappear from the results returned by getPurchasesList . The time it takes for this to happen varies. It could be minutes to over 10 hours. I think this depends on when Google Play refreshes its cache. It seems that one can open Google Play to refresh its cache. In one case, getPurchasesList still returned a refunded purchase more than 10 hours after refunding, but it stopped returning it as soon as Google Play is opened.

Answer 1

Have you checked out the voided purchase list API? It returns a list of cancelled, refunded or charged-back purchases.

Answer 2

Scrape the Google Console. That's what I do.
