**PUT** `https://www.digicert.com/services/v2/webhook/{{webhook_id}}/send-challenge`

Use this endpoint to send an event with a challenge token a webhook endpoint. The challenge token event has this format:

```json
{
  "event": "challenge_webhook_endpoint",
  "data": {
    "token": <token>,
    "webhook_id": 12345
  }
}
```

After receiving the token, use the [Verify challenge token](https://dev.digicert.com/md/certcentral-apis/services-api/webhooks/verify-challenge-token.md) endpoint to send the token back to DigiCert and complete the verification challenge.

Challenge tokens are valid for 30 minutes. If your token expires before you complete the verification challenge, use the **Send challenge token** endpoint to send another one.
