Finternet Payment Gateway Documentation

Welcome to the Finternet Payment Gateway API documentation. This documentation provides everything you need to integrate programmable payment infrastructure into your application.

What is Finternet Payment Gateway?​

Finternet is a programmable payment gateway that gives your app fast, reliable digital payments through a simple, familiar payment experience that users already know how to use. Instead of dealing with slow or complicated payment systems, you get clean, rule-based payment flows that your app can automate or customize with AI. This lets you build things like automatic payouts, conditional transfers, usage-based billing, recurring charges, milestone-based releases, and other new payment ideas that traditional systems can’t support. With these building blocks, you can create the next generation of AI-powered, payment-driven products.
