### Verify Webhook Signature (Node.js)

Source: https://faucetpay.io/api-docs

Code snippet demonstrating how to verify the HMAC-SHA256 signature of a webhook delivery in Node.js.

```APIDOC
## Verify Webhook Signature (Node.js)

### Description
Recompute the HMAC over the raw request body with your webhook secret and constant-time compare it to the X-FaucetPay-Signature header.

### Method
N/A (verification logic)

### Code Example
```javascript
import crypto from 'node:crypto';

// rawBody = the exact bytes you received (verify BEFORE JSON.parse)
const signature = req.headers['x-faucetpay-signature']; // 'sha256=<hex>'
const expected =
  'sha256=' + crypto.createHmac('sha256', WEBHOOK_SECRET).update(rawBody).digest('hex');

const ok =
  signature &&
  crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected));
if (!ok) return res.status(401).end();
```

### Notes
- Always verify the signature before parsing the JSON body.
- Use constant-time comparison to prevent timing attacks.
