After purchasing an annual product package, the apple server notification interval is once an hour, and the user is not charged, while the transactionId is different for each notification. The app is an official environment and has been audited, can anyone help me? Thank you!

I purchased an auto-renewed item and then my server received a notification from the apple store server, is there any way I can know which user the transaction information in this notification belongs to?
