I noticed that it's false for both valid an fraudulent purchases (although it is possible that it has changed after saving this data). A few others got cancelled at around 26 hours after the purchase and we suspect these have to do with the Family Link based on feedback from a user who contacted our support.Ĭould it be that the changes in Google Play Billing Library 3 are causing this, such as the differences in the transaction identifier/orderId behavior? It's hard to tell exactly which party is rejecting the faulty payment method when using IAP 2.1.1.Ĭomparing new and old receipts, the old ones don't have things like acknowledgement flag.

These purchases got cancelled very quickly after receiving the consumable (usually a minute or less). This makes us to wonder how the plugin can affect the validity of the purchases or payment methods.Ĭlick to expand.I would say that there were about a dozen users who were doing this and about seven who seemed to make these type of purchases almost non-stop during specific hours (they were Indonesian). The users do not get their product this time. The issue was fixed and now we see the following events in the Play Console: 'Order received', then immediately 'There was an issue charging the customer’s payment method' and after five minutes 'This order could not be completed and was canceled'. We suspected that this must be an issue in Google's end, because the faulty orders were accepted by their API and they're the ones creating the orders, right? But we noticed that these started happening after we updated the plugin, so we blindly reverted the version to 2.1.1 (again). We can see that the IAP plugin is sending errors with of type 'Unknown' as well.

We have no idea how the users can cancel the purchases like this. The thing is, the Google API at our backend accepts the initial receipt before the cancel and the user gets their product. The Family Link ones seem to have a wait time of over 24 hours before the cancel actually happens. In the Google Play console, these purchases have an 'Order received' event, then 'The order is being canceled' after a minute or so and 'The order could not be completed and was canceled' five minutes later. We're using server backend to verify the receipts and this was happening with IAP version 2.2.6. A user reported that they could abuse the Family Link to produce this: The purchase requires permission from a guardian but closing the application at the right moment will trigger the purchase anyway. There seems to be some kind of exploit that forces the purchases to cancel, not sure if it's about the application, faulty payment method or something else. We had thousands of dollars worth cancelled IAPs just last weekend on Android. Not entirely sure if this is related, since we're only using consumable products, but we've had similar issues nonetheless.
