### Messaging Webhooks

Messaging webhooks notify you when participants send messages or when new conversations are created. These events are only triggered for messages sent by participants, not by researchers.

<Note>
  Messaging webhooks are available in staging (since January 14, 2026) and in
  production (since February 11, 2026).
</Note>

### To set up a webhook

* Create a `POST` to `/v1/webhooks` with the desired url for webhooks to be sent to.

```
 {"url": "https://my-webhooks.com"}
```

* This will return a body with your organizationId, teamId, url, privateKey, and the webhook id to be used to validate webhook responses
  ```
  {
    "organizationId": "67c4f87adbb9ff9dc5322fc8",
    "teamId": "67c4f87adbb9ff9dc5322fe0",
    "url": "https://webhook.site/7d91c565-0f90-4340-8774-f3131f61606c",
    "privateKey": "44450f9c-f43c-4c26-98cb-53bdc0f49fde",
    "id": "6960367acd7d61583859e0e0"
  }
  ```

### To Validate a webhook signature

<CodeGroup>
  ```node node theme={null}
  const signatureHeader = request.headers['Respondent-Webhook-Signature'];
  const body = request.body;
  const algorithm = signatureHeader.substring(0, signatureHeader.indexOf('='));
  const receivedSignature = signatureHeader.replace(algorithm + '=', '');
  const privateKey = '<privateKey>';

  const hmacBodyDigest = createHmac(algorithm, privateKey)
  .update(JSON.stringify(body))
  .digest('base64');

  if (hmacBodyDigest === receivedSignature) {
  // Handle webhook events
  return HttpStatusCode.Ok;
  } else {
  return HttpStatusCode.Forbidden;
  }

  ```
</CodeGroup>

### Webhook responses and retries

Partners must return a 2xx status code within 3 seconds; otherwise, we’ll retry up to 5 times in 10-minute intervals.
