Transaction API

Overview

The Transaction API enables merchants to process payments and obtain authorization for payment pop-ups displayed on the checkout page. It supports server-to-server communication via RESTful APIs, offering a variety of payment options including Credit Cards, Debit Cards, Net Banking, UPI, Wallets, and NEFT/RTGS. The API is optimized for both web and mobile devices, with a retry option to reduce customer drop-offs in case of transaction failures.
