# Test Webhook

> Send a test event to verify your webhook endpoint is reachable and signature verification works.

## Path Parameters

<ParamField path="id" type="string" required>
  The webhook UUID.
</ParamField>

## Behavior

Dispatches a `completion.created` event with `_test: true` in the data payload. The delivery uses the same HMAC signing, SSRF checks, and retry logic as real events.

## Example

<CodeGroup>
  ```bash curl theme={null}
  curl -X POST https://www.hitheo.ai/api/v1/webhooks/WEBHOOK_ID/test \
    -H "Authorization: Bearer $THEO_API_KEY"
  ```

  ```typescript SDK theme={null}
  await theo.testWebhook("WEBHOOK_ID");
  ```
</CodeGroup>

### Response

```json theme={null}
{ "sent": true }
```

### Test event payload your server receives

```json theme={null}
{
  "id": "evt_abc123...",
  "type": "completion.created",
  "created": "2026-04-15T12:00:00.000Z",
  "data": {
    "_test": true,
    "message": "This is a test event from Theo. If you received it, your webhook is working!"
  }
}
```

<Tip>
  Use the [delivery log](/api-reference/webhooks/deliveries) to check whether the test was delivered successfully.
