PhonePe for WHMCS

PhonePe for WHMCS enables invoice payments through PhonePe Standard Checkout V2:

• Flexible checkout: Choose between a full-page redirect or an in-page popup (iframe) overlay.
• Dual verification: Payment notifications arrive via SHA256-signed webhooks and are confirmed against PhonePe's API before invoices update.

Setup → Payment Gateways → PhonePe

For: a WHMCS business with a PhonePe Business account (KYC-verified) collecting payments through PhonePe's checkout or in-page popup.

How it works

Step	What happens
Pay Now	The customer clicks Pay Now on their invoice
Checkout	PhonePe opens as a full-page redirect or an in-page popup
Webhook + API check	PhonePe notifies your site; the gateway verifies the webhook and re-checks the status via the API
Marked paid	The invoice is marked paid, and the transaction fee is recorded

What you'll need

A PhonePe Business account (KYC-verified) with Client ID / Client Secret, plus SSL on your domain for the webhook. See Requirements and the PhonePe setup guide.
