Cardtonic Gift Card Developer API

The Cardtonic Gift Card Developer API enables merchants and platforms to integrate gift card services into their websites, mobile apps, and point-of-sale systems. The API exposes a catalog of more than 14,000 gift cards for purchase and sale, bulk ordering with instant reporting, inventory and redemption management, and branding/customization hooks. As of 2026 the API is in waitlist mode and developer credentials are issued through Cardtonic on request.
