# Track Order

After creating Fast Charge orders, use this endpoint to check their status — whether each order is still waiting to be matched or has already been matched.

{% hint style="info" %}
This endpoint requires an API key. See [Authentication](/developers/authentication.md) for how to obtain a key and fund your internal account.

    "message": "TSAS:106 API_KEY_REQUIRED"
}
```

```

**400 Bad Request** — a required field is missing or invalid. The message names the offending field:

```json
