Integrating UPI & Indian Payment Gateways in eCommerce Without Losing Webhook Orders

Learn how server-to-server HMAC webhooks prevent dropped orders when customers pay via Google Pay, PhonePe, or Paytm on your eCommerce store.

With UPI accounting for over 75% of digital retail payments in India, every eCommerce website in Patna must offer seamless UPI Intent and QR checkout via gateways like Razorpay, Cashfree, PhonePe PG, or PayU.

Why Browser Redirects Alone Fail on Mobile

When a mobile shopper switches from Chrome to their UPI app to approve a payment, mobile operating systems occasionally suspend the background browser tab. Relying solely on a frontend redirect causes "payment deducted, order missing" issues.

The Solution: Idempotent Server-to-Server Webhooks

Our Payment Gateway Support engineers implement cryptographic HMAC-SHA256 webhook listeners that receive instant bank confirmation directly on your server—marking orders paid and dispatching GST invoices reliably every time.
