A gift card API (Application Programming Interface) is a set of rules and protocols that enable different software applications to communicate and manage gift card operations. It allows businesses to integrate gift card functionalities into their existing systems, such as e-commerce platforms, mobile apps, and point-of-sale (POS) systems.

The Tremendous gift card API gives you programmatic access to send 2000+ payout options to recipients. If you’re thinking of integrating rewards or payouts into your website, app, or business workflows, our API will have you up and running in hours.
