I am trying to integrate with MercuryPay Gift Cards. We are using dsiPDCX to send the transaction requests. I am trying to figure out what I need to send in for a gift card so when someone needs to enter a gift card number manually they can key in the card information. Today for credit cards we send in Prompt in the AcctNo node which causes the UI to enter the CC info to open. Does gift card work the same way as credit cards? I was also wondering if there is a list of test gift cards I am missing.
