# Authentication

> Authenticating requests with API-Key

Every request is validated and authenticated by the API-key header. You can view your API-Key when you
are logged into the web-app in [https://live.hellotracks.com](https://live.hellotracks.com), open API & Integrations page under More in
the main menu. Make sure to enable APIs in the API section.

```bash theme={null}
curl -X POST https://api.hellotracks.com/api/$endpointname \\
    --header 'API-Key: ABCDEF.ABCDEFGHIJKLMNOPQRSTUVWXYZ123456' -d \\
'
    {
        "data":{
          ...
        }
    }
'
```

Parameters for `/api` endpoints are defined in the required `data` field. `/api` endpoints use the `POST` method; REST endpoints under `/v1` use the HTTP method documented for each route.
