# Test Webhook

> Send a test delivery to verify your endpoint is reachable and configured correctly.

## Endpoint

```
POST /v3/webhooks/:id/test
```

Sends a synthetic event with `"test": true` in the payload. The event type is the first one in your webhook's `event_types` list.

## Example

```bash theme={null}
curl -X POST https://api.polynode.dev/v3/webhooks/wh_451e06ca0534/test \
  -H "Authorization: Bearer YOUR_API_KEY"
```

## Response

```json theme={null}
{
  "delivered": true,
  "status_code": 200,
  "latency_ms": 89
}
```

## Test Payload

Your endpoint receives:

```json theme={null}
{
  "id": "test_a1b2c3d4-5e6f-7a8b-9c0d-1e2f3a4b5c6d",
  "type": "trade",
  "created_at": "2026-05-14T15:00:00+00:00",
  "data": {
    "test": true,
    "message": "This is a test delivery from polynode webhooks"
  }
}
```

The delivery includes all standard webhook headers (`X-Webhook-ID`, `X-Webhook-Event`, `X-Webhook-Timestamp`, `X-Webhook-Signature`) so you can verify your signature validation logic.
