# Cancel an in-person refund

`POST /voidPendingRefund`

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](https://docs.adyen.com/point-of-sale/basic-tapi-integration/refund-payment/cancel-unreferenced).
