I'm setting up and testing In-app Purchases for android. I was able to make a test purchase. However, I can not find a way to delete that order to keep on testing. According to this article, I should be able to cancel it: Cancel purchases manually—you can go to the Google payments merchant center, look up the transaction, and then cancel it. You can find transactions by looking up their order numbers.
But my Payments Merchant center has no transactions on it and I'm using my own product ID's and not the product IDs for static responses. Help!
