How to Handle Refund Notifications?

In apple’s document： https://developer.apple.com/documentation/storekit/original_api_for_in-app_purchase/handling_refund_notifications

memtion in document： Your server is responsible to parse and interpret all notifications from App Store Server. For the REFUND notification, identify the specific transaction, product ID, and relevant dates from the response:

Find the most-recent transaction for the product_id in the unified_receipt.latest_receipt_info by checking the purchase_date to select the most-recent transaction.

The date when App Store issued the refund is in the cancellation_date_ms field for this transaction.

  • My problem is that , we find that unified_receipt.latest_receipt_info is an array, It contains multiple trasactions and these t'rascations all have ”cancellation_date_ms“ field .

I would like to know if I should process all the trasactions have field ”cancellation_date_ms“ or just the latest one？

please help！！

For this reason I would recommend using the v2 Server Notifications as those notifications will only contain the transaction for the event. But typically for v1 notifications for a type of REFUND or CANCEL, it is recommended to sort transactions by cancellation_date, typically there will be a transaction with a cancellation date near when the notification was first sent.

  • Other transactions with cancellation_date should I handle? Even though these transactions not the most-recent one

One place to start is to match the transaction IDs from the notification that you got against the latest receipt -- with this amount of information, it is uncertain exactly what you need to process – please also ensure the bundleId and appAdamId matches your application.
