After the backend service receives the RTN notification, how to obtain the transaction amount for this transaction?

Fire Devices & Appstore Q&A

I received a push notification from Amazon’s server through real-time notifications, which included a receiptId. I used the receiptId to send a request to the RVS server to verify the receipt and obtain all the information related to the receipt. However, this information did not include the price information of this transaction. How can I obtain the price and currency information of this transaction?

Hi there,

Welcome to the forum, and thanks for posting! Price or currency related fields are not included when exchanging data via the services you mentioned. You can receive receipt IDs through Real-Time Notifications, and you can use Receipt Verification Service (RVS) to to verify receipts, with fields like cancelDate, productType, and fulfillment status included. But price-related fields are not there by design. You will need to implement custom logic in your app / on your server to store pricing/currency info. Thanks!

Hi,

Thank you for your prompt and helpful response!

I would like to ask further, does Amazon provide any API or interface that would allow my server to retrieve the price and currency information for IAP products? Or are there any other methods through which I could obtain this information?

Thanks again for your assistance.
