[Solved] IAP - ProcessPurchase called every time app is loaded after IAP cancellation

Unity Services
1

ProcessPurchase is being called every time I load my app.

This started when I cancelled the IAP through Google’s merchant account page (which I did so that I could re-test buying that specific non-consumable product).

I’m using GameSparks to validate receipts, and it returns an error each time as the receipt has already been used. I then show a message to the player telling them their purchase has failed, which obviously doesn’t make sense in this case.

I’m also aware that if I delete the app, ProcessPurchase is called automatically to restore purchases (Unity - Manual: Restoring Transactions) - I can see the same problem happening here - the receipt will be checked and shown to be a duplicate.

I tried using

Directory.Delete(Path.Combine (Path.Combine (Application.persistentDataPath, "Unity"), "UnityPurchasing"), true);

as shown in [Solved] Is it possible to delete an IAP non-consumable product? - Unity Services - Unity Discussions but it hasn’t made a difference.

My questions are:

  1. Why is ProcessPurchase being called after I’ve cancelled an IAP and how do I stop it?
  2. Assuming ProcessPurchase is meant to be called when an IAP is cancelled/if it’s called when an app is reinstalled, is there a way to check (probably inside the ProcessPurchase method) whether ProcessPurchase is being called due to an actual purchase?

Try clearing the cache on the google play app, it is likely that the cancellation has not propagated to it.

Also if you return PurchaseProcessingResult.Complete from ProcessPurchase you should not be informed of the purchase again.
