Question UDP Purchase Failing, need to consume first.

Hi, I am having trouble completing the IAP purchase with UDP. I am using a demo project to simplify things, and am able to initialize correctly, with sandbox login. I also get the appropriate prompt from UDP.

But when i attempt to purchase (these are both buttons outside, initialize() and purchaseitem()) I get "Invalid Operation: iap 1500keys needs to be consumed first."

Could anyone tell what I am doing wrong? Any Help will be appreciated.

From What I can tell, it goes to OnPurchaseFailed() instead of OnPurchase(), where I assume I am supposed to consume the product.

I have already checked the Client ID, Client Secret, etc and they match with the original project's.

Edit : Error code - 300 on Android Studio.

Edit: Found solution, the error was asking me to consume the purchase probably made way earlier but not consumed. Using Query Inventory I could get all pending purchase and consume them, after which I was able to do further purchases.

 

hi , I am struggling with the same issue although the IAP is for non-consumable. could you share a bit more of how you solved this?
