how do I get last years apple pay receipts

Hello,

Apple Pay is basically a gatekeeper between your cards and merchants you pay. The merchants would provide receipts and your card issuer would provide statements showing the card activity. You can see recent transactions for cards used for Apple Pay in your Wallet App but only the merchant could provide receipts showing what was purchased.

"Some transactions might look different than the final charge. Depending on your bank or card issuer, you might see only initial authorization amounts, or you might see different transaction amounts from locations such as restaurants, gas stations, hotels, and rental car companies.

For the most accurate record of your transactions, refer to the credit or debit statement from your bank or card issuer."

If you need the receipts you should first get your statements so you know what transactions you need the receipts for. Then you would want to contact the merchants to request new receipts. If you have a lot of transactions from a single merchant I recommend calling them so they have time to print them for you. You will likely need to provide the merchants with your device account number so they can find them.

If you are seeing "apple.com/bill" on the bank side that would indicate a charge related to an Apple ID payment method rather than Apple Pay. Since Apple was the merchant you can find the receipts which we're likely also emailed to you at the time of purchase.
