I wonder why get IAP transaction history Api will return many signedTransactions

I just enter one oritransactionid to app store server, but why I can reveive a array for signedTransactions?

One oritransactionid can corresponding many purchases via user?

Thank you very much

The transaction history API returns the customer's entire history, with the response described as: "A response that contains the customer’s transaction history for an app."

See https://developer.apple.com/documentation/appstoreserverapi/historyresponse

Thank you! But I wonder what is customer mean?SignedTransactions include that appleid‘s user bought in other apps? The path params originalTransactionId I put in request URL is created in my app’s purchased
