Razorpay Webhooks

Razorpay is an India-focused payments platform. It notifies your application of payment lifecycle events (orders, payments, refunds, subscriptions, settlements, disputes) by sending an HTTP POST webhook with a JSON payload to your endpoint.

Understanding Razorpay event types and payload structure

Verification (core)

Razorpay signs each webhook with HMAC-SHA256 over the raw request body, hex-encoded, in the X-Razorpay-Signature header. The key is the webhook secret you set in the dashboard (not your API key). Verify the raw body — do not JSON.parse before verifying.

The official razorpay Node SDK exposes a static helper:

const Razorpay = require('razorpay');

// rawBody: the raw HTTP body as a string/Buffer (NOT parsed JSON)
// signature: value of the X-Razorpay-Signature header
// secret: RAZORPAY_WEBHOOK_SECRET from the dashboard webhook config
const isValid = Razorpay.validateWebhookSignature(rawBody, signature, secret);
// returns true/false

No Node SDK (e.g. Python/FastAPI)? Compute it manually with a timing-safe compare:

import hmac, hashlib
expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest()
is_valid = hmac.compare_digest(expected, signature_header)

Common Event Types

The event type is in the JSON body's event field (not a header).

Event	Triggered When
`payment.authorized`	Payment authorized but not yet captured
`payment.captured`	Payment successfully captured
`payment.failed`	Payment attempt failed
`order.paid`	An order is fully paid
`refund.processed`	A refund has been processed
`subscription.charged`	A subscription charge succeeded

For the full event reference, see references/overview.md and Razorpay's webhook events docs.

Environment Variables

RAZORPAY_WEBHOOK_SECRET=your_webhook_secret   # From Dashboard → Settings → Webhooks

The webhook secret is a value you choose when creating the webhook in the Razorpay dashboard — it is separate from your API key ID/secret.

Local Development

# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 razorpay --path /webhooks/razorpay

Recommended: webhook-handler-patterns

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

Handler sequence — Verify first, parse second, handle idempotently third
Idempotency — Prevent duplicate processing (Razorpay retries and may deliver duplicates)
Error handling — Return codes, logging, dead letter queues
Retry logic — Provider retry schedules, backoff patterns
