Refunds For any goods purchased with a card that are accepted for return, or for any services that are terminated or cancelled, or where any price adjustment is made, merchants may need to refund the transaction amount to the cardholder’s account. Card schemes require a refund to only be processed on the same card number that was used in the original sales transaction and for an amount which is no more than the original transaction. Cancel/Void Merchants and PSPs are able to cancel or void a transaction which has been authorised by the card issuer prior to settlement. A transaction may need to be cancelled if the cardholder completes a payment transaction in error, for the wrong amount or would prefer to choose a different method of payment. Cancels can only be processed on previously authorised transactions which have not yet been cleared by the card issuers and a cancellation will always be performed for the entire transaction amount. Manually Performed Cancel and Refund Transactions Cancel and refund transactions can be performed using the Merchant Administration System, described in the relevant user interface document or via an API call from the merchant or processor site as described below. Some merchants and PSPs on the MYGW Gateway are only able to perform refund and void transactions using the Merchant Administration System. Those merchants and PSPs are not able to use the refund and void API calls. |
