# HubSpot Webhooks
## When to Use This Skill
- Setting up HubSpot webhook handlers
- Verifying `X-HubSpot-Signature-v3` headers
- Debugging signature verification failures
- Handling CRM events like contact creation, property changes, or deal events
- Migrating from HubSpot signature v1/v2 to v3
## Essential Code (USE THIS)
HubSpot's official SDKs ship a signature helper: `Signature.isValid` in Node (`@hubspot/api-client`) and PHP, `Signature.is_valid` in Python and Ruby. The examples here verify manually with HMAC-SHA256 and base64 so the signed string and the timing-safe comparison are explicit; see [references/verification.md](references/verification.md) for the SDK route.
### HubSpot Signature Verification (JavaScript)
```javascript
const crypto = require('crypto');
const MAX_AGE_MS = 5 * 60 * 1000; // 5 minutes
/**
* Verify HubSpot v3 webhook signature.
*
* Signed content = HTTP method + request URI + raw body + timestamp
* Signature is HMAC-SHA256 (base64) of that string using the app's Client Secret.
*/
function verifyHubSpotWebhook({ method, uri, rawBody, timestamp, signature, secret }) {
if (!signature || !timestamp || !secret) return false;
// Reject stale requests (older than 5 minutes)
const ts = Number(timestamp);
if (!Number.isFinite(ts) || Math.abs(Date.now() - ts) > MAX_AGE_MS) return false;
const body = Buffer.isBuffer(rawBody) ? rawBody.toString('utf8') : rawBody;
const signedContent = `${method}${uri}${body}${timestamp}`;
const expected = crypto
.createHmac('sha256', secret)
.update(signedContent, 'utf8')
.digest('base64');
try {
return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signature));
} catch {
return false;
}
}
```
### Express Webhook Handler
```javascript
const express = require('express');
const app = express();
// CRITICAL: Use express.raw() - HubSpot requires raw body for HMAC verification
app.post('/webhooks/hubspot',
express.raw({ type: 'application/json' }),
(req, res) => {
const signature = req.headers['x-hubspot-signature-v3'];
const timestamp = req.headers['x-hubspot-request-timestamp'];
// Reconstruct the full request URI (HubSpot signs the URL it called)
const uri = `${req.protocol}://${req.get('host')}${req.originalUrl}`;
const valid = verifyHubSpotWebhook({
method: req.method,
uri,
rawBody: req.body,
timestamp,
signature,
secret: process.env.HUBSPOT_CLIENT_SECRET,
});
if (!valid) {
console.error('HubSpot signature verification failed');
return res.status(400).send('Invalid signature');
}
// HubSpot sends an array of events in each webhook
const events = JSON.parse(req.body.toString());
for (const event of events) {
switch (event.subscriptionType) {
case 'contact.creation':
console.log('New contact:', event.objectId);
break;
case 'contact.propertyChange':
console.log('Contact property changed:', event.objectId, event.propertyName);
break;
case 'deal.creation':
console.log('New deal:', event.objectId);
break;
default:
console.log('Unhandled event:', event.subscriptionType);
}
}
res.status(200).send('OK');
}
);
```
### Python (FastAPI) Signature Verification
```python
import hmac
import hashlib
import base64
import time
MAX_AGE_MS = 5 * 60 * 1000 # 5 minutes
def verify_hubspot_webhook(method: str, uri: str, raw_body: bytes,
timestamp: str, signature: str, secret: str) -> bool:
if not signature or not timestamp or not secret:
return False
try:
ts = int(timestamp)
except ValueError:
return False
if abs(int(time.time() * 1000) - ts) > MAX_AGE_MS:
return False
body = raw_body.decode("utf-8")
signed_content = f"{method}{uri}{body}{timestamp}"
expected = base64.b64encode(
hmac.new(secret.encode("utf-8"), signed_content.encode("utf-8"), hashlib.sha256).digest()
).decode("utf-8")
return hmac.compare_digest(expected, signature)
```

## Common Event Types
HubSpot calls these `subscriptionType` values. Each webhook delivery contains an array of one or more event objects.
| Event | Description |
|-------|-------------|
| `contact.creation` | A new contact was created |
| `contact.propertyChange` | A property on a contact changed |
| `contact.deletion` | A contact was deleted |
| `company.creation` | A new company was created |
| `company.propertyChange` | A property on a company changed |
| `deal.creation` | A new deal was created |
| `deal.propertyChange` | A property on a deal changed |
| `ticket.creation` | A new ticket was created |
> **For full event reference**, see [HubSpot Webhooks API](https://developers.hubspot.com/docs/api/webhooks).
## Environment Variables
```bash
HUBSPOT_CLIENT_SECRET=your_app_client_secret # From your HubSpot app settings
```
The signing key is your **App's Client Secret** (sometimes called Application Secret), not a private app token.
## Signature Versions
HubSpot has shipped three signature versions:
- **v1** (`X-HubSpot-Signature`) - SHA-256 of `clientSecret + body`. **Deprecated.**
- **v2** (`X-HubSpot-Signature`, `X-HubSpot-Signature-Version: v2`) - SHA-256 of `clientSecret + method + URI + body`. **Deprecated.**
- **v3** (`X-HubSpot-Signature-v3`, requires `X-HubSpot-Request-Timestamp`) - HMAC-SHA256 (base64) of `method + URI + body + timestamp`. **Use this.**
New integrations should use v3 only. A v4 webhooks API is in beta on HubSpot's new developer platform but uses different mechanics; pin to v3 for stability.
## Local Development
```bash
# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 hubspot --path /webhooks/hubspot
```
Then paste the Hookdeck URL into your HubSpot app's webhook settings as the target URL.
