# 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.

## When to Use This Skill

* How do I receive Razorpay webhooks?
* How do I verify the `X-Razorpay-Signature` header?
* Why is my Razorpay webhook signature verification failing?
* How do I handle `payment.captured`, `order.paid`, or `subscription.charged` events?
* 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:

```javascript
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:

```python
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 |

## Environment Variables

```bash
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

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

```
