Hi, Is the 'receiptId' sent by amazon in response to IAP remains same on renewal of the subscription for the same user, or changes? And also What will be the 'purchaseDate' of the subscription after renewal? Will it be the same(initial one, when the first time user subscribed) or changes to the day of renew of subscription?
Hello, Please see more information at
http://developer.amazon.com/public/apis/earn/in-app-purchasing/docs-v2/faq-for-iap-2.0 - section Subscription Item Questions. Q: Does the value of receiptId change for every renewal period? A: Whether or not the receiptId changes depends on whether the customer's subscription was continuous or not: If the subscription is continuous and has never been canceled at any point, the app will only receive one receipt for that subscription/customer. If the subscription was not continuous, for example, the customer did not auto-renew, let the subscription lapse, and then subscribed again a month later, the app will receive multiple receipts. Q: Does the purchaseDate value represent the initial purchase date or every renewed purchase? A: The purchaseDate represents the initial purchase date, not the purchaseDate of subsequent renewals.
