Cancel an in-person refund

This endpoint allows you to cancel an unreferenced refund request before it has been completed.

In your call, you can refer to the original refund request either by using the tenderReference, or the pspReference. We recommend implementing based on the tenderReference, as this is generated for both offline and online transactions.

For more information, refer to Cancel an unreferenced refund.
