Card9 API / Payment Gateway

Now you can connect your website, shopping cart, or any application to our API and utilize real-time gift card processing! Much like a credit card payment gateway allows you to charge credit cards, our API allows you to check balances, charge cards, reload cards, issue refunds on cards you've created, and create virtual (non-printed) gift cards instantly.
