PhonePe Checkout Gateway for WHMCS enables businesses to securely accept one-time payments through PhonePe Standard Checkout V2 directly within WHMCS. Built using PhonePe Payment Gateway V2 APIs, the module provides a smooth and reliable checkout experience while automatically updating invoices after successful payments. The gateway securely initiates payments, redirects customers to the PhonePe Checkout page, verifies transaction status, processes authenticated webhooks, and prevents duplicate transactions for accurate payment processing. Designed for flexibility, the module supports both Sandbox and Production environments, making testing and deployment simple. OAuth-based authentication ensures secure communication with PhonePe APIs, while built-in refund support allows administrators to process refunds directly through the gateway.
