Gift Card Credit

You use a Gift Card Credit transaction to refund money to a customer that used a (Closed Loop) Gift Card for the purchase, even if Worldpay did not process the purchase. You have a choice of two structures.

You use the message type containing a transaction Id to apply a credit for a transaction processed by Worldpay. You use the message type containing a order ID to apply a credit for a transaction not processed by Worldpay.
