I'm trying to find a gift card solution for the clover. We already have to clover integrated into our POS System with a c# application that communicates with the POS. I loaded $1.00 to a giftcard using the gift card app and tried to run a $0.01 transaction on the giftcard using the USB Pay Display App but it says that the transaction has been declined. I've read that people do this a custom tender with a button linking to the giftcard app. Is there a way to do that using the USB Pay Display App? Another option would be if there's a REST API for the gift cards that we could run on the POS side instead of the clover. I'm just looking for a solution to the giftcard problem. Thanks in advance.
