Razorpay Payment Gateway for WHMCS

Accept Razorpay payments directly through WHMCS with a modern, reliable payment gateway module built for current WHMCS and PHP environments.

The Ucartz Razorpay WHMCS module is a rebuilt and improved version of the original Razorpay WHMCS integration. It addresses several long-standing issues around payment verification, partial payments, stale orders, refunds, webhooks, and transaction reconciliation.

Why use this module?

Payment gateway integrations need to correctly handle more than just a successful checkout. Partial payments, invoice changes, refunds, duplicate callbacks, webhooks, chargebacks, and gateway fees can all affect the final invoice balance.

This module is designed to keep Razorpay and WHMCS transaction records synchronized throughout the complete payment lifecycle, while avoiding several problems found in older implementations.

The module has been tested with real WHMCS installations and different payment scenarios, including standard payments, partial payments, late fees, refunds, and webhook events.
