Mercury Payment GiftCard - Split Purchase Notes
When submitting a Gift Card payment transaction you have 2 choices.
-
When you know the GiftCard has sufficient balance, you may fund the purchase with the GiftCard number only.
-
When you know ahead of time or suspect that the value on the card is insufficient, fund the purchase with the GiftCard number and Credit Card data.
When the remaining balance on a giftcard is insufficient to fund the entire purchase amount a split purchase can be made. With a split purchase the giftcard is debited for the full remaining balance left on the card. The remaining portion is then debited against a credit card. To activate this mode a ’normal’ credit card auth is submitted containing the necessary credit card information together with a valid giftcard number (‘mpgiftcard’ field) and associated giftcard CVV # (‘mpcvv’ field).
Notes:
-
Response variable ‘card-amount’ reflects the original order total submitted.
-
Response variable ‘acountGC’ reflects the amount charged to the giftcard.
-
Response variable ‘amountCC’ reflects the amount charged to the credit card.
-
Response variable ‘balance’ will contain the remaining balance on the giftcard.
