# Webhooks

> Get notified when records change — HTTP POST to your endpoint on every create, update, or delete.

export const VimeoEmbed = ({videoId, title = 'Video'}) => <div style={{
  padding: '69.01% 0 0 0',
  position: 'relative',
  margin: '32px 0px',
  borderRadius: '16px',
  overflow: 'hidden',
  border: '2px solid black'
}}>
    <iframe src={`https://player.vimeo.com/video/${videoId}?autoplay=1&loop=1&autopause=0&background=1&app_id=58479`} frameBorder="0" allow="autoplay; fullscreen; picture-in-picture; clipboard-write" style={{
  position: 'absolute',
  top: 0,
  left: 0,
  width: '100%',
  height: '100%',
  transform: 'scale(1.1)'
}} title={title} />
  </div>;

Twenty sends an HTTP POST to your URL whenever a record is created, updated, or deleted. All object types are covered, including custom objects.

## Create a Webhook

1. Go to **Settings → Developers → Webhooks**
2. Click **+ Create webhook**
3. Enter your webhook URL (must be publicly accessible)
4. Click **Save**

The webhook activates immediately and starts sending notifications.

<VimeoEmbed videoId="928786708" title="Creating a webhook" />

### Manage Webhooks

**Edit**: Click the webhook → Update URL → **Save**

**Delete**: Click the webhook → **Delete** → Confirm

## Events

Twenty sends webhooks for these event types:

| Event | Example |
| - | - |
| **Record Created** | `person.created`, `company.created`, `note.created` |
| **Record Updated** | `person.updated`, `company.updated`, `opportunity.updated` |
| **Record Deleted** | `person.deleted`, `company.deleted` |

All event types are sent to your webhook URL. Event filtering may be added in future releases.

## Payload Format

Each webhook sends an HTTP POST with a JSON body:

```json theme={null}
{
  "event": "person.created",
  "data": {
    "id": "abc12345",
    "firstName": "Alice",
    "lastName": "Doe",
    "email": "alice@example.com",
    "createdAt": "2025-02-10T15:30:45Z",
    "createdBy": "user_123"
  },
  "timestamp": "2025-02-10T15:30:50Z"
}
```

| Field | Description |
| - | - |
| `event` | What happened (e.g., `person.created`) |
| `data` | The full record that was created/updated/deleted |
| `timestamp` | When the event occurred (UTC) |

<Note>
  Respond with a **2xx HTTP status** (200-299) to acknowledge receipt. Non-2xx responses are logged as delivery failures.
</Note>

## Webhook Validation

Twenty signs each webhook request for security. Validate signatures to ensure requests are authentic.

### Headers

| Header | Description |
| - | - |
| `X-Twenty-Webhook-Signature` | HMAC SHA256 signature |
| `X-Twenty-Webhook-Timestamp` | Request timestamp |

### Validation Steps

1. Get the timestamp from `X-Twenty-Webhook-Timestamp`
2. Create the string: `{timestamp}:{JSON payload}`
3. Compute HMAC SHA256 using your webhook secret
4. Compare with `X-Twenty-Webhook-Signature`

### Example (Node.js)

```javascript theme={null}
const crypto = require("crypto");

const timestamp = req.headers["x-twenty-webhook-timestamp"];
const payload = JSON.stringify(req.body);
const secret = "your-webhook-secret";

const stringToSign = `${timestamp}:${payload}`;
const expectedSignature = crypto
  .createHmac("sha256", secret)
  .update(stringToSign)
  .digest("hex");

const receivedSignature = req.headers["x-twenty-webhook-signature"];
const isValid = crypto.timingSafeEqual(
  Buffer.from(expectedSignature, "hex"),
  Buffer.from(receivedSignature, "hex")
);
```

## Webhooks vs Workflows

| Method | Direction | Use Case |
| - | - | - |
| **Webhooks** | OUT | Automatically notify external systems of any record change |
| **Workflow + HTTP Request** | OUT | Send data out with custom logic (filters, transformations) |
| **Workflow Webhook Trigger** | IN | Receive data into Twenty from external systems |

For receiving external data, see [Set Up a Webhook Trigger](/user-guide/workflows/how-tos/connect-to-other-tools/set-up-a-webhook-trigger).
