I have a question about purchase token validation with the google api. So far I send the purchasetoken from the client to my backend and validate it together with the product sku, but how can I validate the amount of the purchased product?
After allowing multiple purchases for the same product, how can I validate the amount together with the purchasetoken and product sku? This is the code that validates only purchasetoken and product sku that I use:
purchases = service.purchases() subscriptions = purchases.subscriptions() subscriptions_get = subscriptions.get( packageName=self.bundle_id, subscriptionId=product_sku, token=purchase_token ) result = subscriptions_get.execute(http=self.http) return result
