Setup Guide

How to connect Razorpay to WhatsApp API

Set up Razorpay webhook

In Razorpay Dashboard → Settings → Webhooks → Add New Webhook. Enter your WA.Expert webhook URL. Select events: payment.captured, payment.failed, refund.created, subscription.charged, subscription.halted.

Configure webhook secret for security

Razorpay sends an X-Razorpay-Signature header with each webhook. WA.Expert verifies this signature using your webhook secret to prevent fraudulent webhook calls. Set this up in WA.Expert → Integrations → Razorpay.

Map customer phone from Razorpay payload

Razorpay payment payloads include contact field with customer phone. Map payload.payment.entity.contact to WA.Expert's "to" field. WA.Expert normalises Indian mobile numbers (with or without +91) automatically.

Create WhatsApp templates for each event type

Create separate approved templates for: payment success, payment failed, refund, and subscription. WA.Expert's template library has pre-approved Razorpay templates ready to use.

Test with Razorpay test mode

In Razorpay test mode, make a test payment. The webhook fires to WA.Expert and the WhatsApp is sent to the test phone number. Verify message content and variable mapping before switching to live mode.

Sample Razorpay → WhatsApp configuration

// Razorpay webhook → WA.Expert
// Event: payment.captured
{
  "entity": "event",
  "event": "payment.captured",
  "payload": {
    "payment": {
      "entity": {
        "id": "pay_29QQoUBi66xm2f",
        "amount": 149900,

      }

FAQ

Razorpay + WhatsApp — common questions

How do I verify Razorpay webhook authenticity in WA.Expert?

WA.Expert verifies the X-Razorpay-Signature header automatically using HMAC-SHA256 with your webhook secret. This prevents fraudulent webhook calls from triggering false WhatsApp receipts. Set your Razorpay webhook secret in WA.Expert → Integrations → Razorpay → Webhook Secret.

What is the Razorpay payment amount format in the webhook?

Razorpay sends payment amounts in paise (1/100 of a rupee). ₹1,499 is sent as 149900 in the webhook payload. WA.Expert automatically converts paise to rupees for display in WhatsApp templates. No manual conversion needed.

Can I send the customer's invoice/receipt PDF via WhatsApp from Razorpay?

Yes — if you generate invoices in Razorpay (via Razorpay Invoices feature), WA.Expert can fetch the invoice PDF via the Razorpay API and attach it to the WhatsApp message as a document. The customer receives the official Razorpay invoice as a PDF on WhatsApp.

Does this work with Razorpay Payment Links?

Yes — Razorpay Payment Link payment events fire the same payment.captured webhook. WA.Expert sends a WhatsApp receipt when payment is made via a Razorpay Payment Link, regardless of whether the link was sent via email, SMS, or WhatsApp itself.

How does Razorpay subscription WhatsApp work for monthly billing?

For each successful subscription charge (subscription.charged event), WA.Expert sends a WhatsApp receipt to the subscriber. For failed subscription charges (subscription.halted), WA.Expert sends a recovery WhatsApp with instructions to update payment method. This automatically handles the full subscription billing communication lifecycle.

Can I use Razorpay + WA.Expert for marketplace payouts?

Yes — Razorpay Route (marketplace payouts) fires webhook events when transfers to vendors are processed. WA.Expert sends WhatsApp payout notifications to vendors via the transfer.settled webhook event.
