the original_transaction_id parameter, present on iTunes receipts, and which represents the primary purchasing order on our db, has been changed descriptively as follows: "This value is useful for connecting multiple iOS 6 style transaction receipts for the same individual customer's subscription"
I did not see this statement until this summer.
Since it is the field we use to match our purchases and iTunes purchases, I need to clarify this important statement.
The official reference doc is https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ReceiptFields.html
where it describes the original_transaction_id parameter
I have a previous version of the doc and this statement was NOT present.
Now Apple says to use web_order_line_item_id as match key but our db did not use it (since Apple did not say that before) and therefore can not match the previous purchases. We need to use original_transaction_id, how can we do?
