Cancel a charge (refund)

Learn how to refund payments to your customers.


Canceling a charge transfers the money back from you (the merchant) to the customer. This is alternatively called refund. You can only perform the cancel transaction on an existing charge. This transaction is possible for all payment methods.

Refund on payment
It is NOT possible to do a refund on the payment resource itself.


Refund is triggered by calling payments/{codeororderid}/charges/{txncode}/cancels endpoint. You can call the cancellation charge with an amount. In this case, only this part of the charge amount is transferred back. If you do not specify an amount, the entire charge is canceled. You can also provide transaction’s description during refund.
