# Authentication

The Sofar API uses token-based authentication. To get started using the Sofar API, you'll need to retrieve or generate an authentication token.

{% hint style="info" %}
Get your authentication token [**here**](https://spotter.sofarocean.com/api)**.**
{% endhint %}

The authentication token is tied to your account, and will grant API access to all resources owned by or shared with your account. You can regenerate the authentication token at any time at [spotter.sofarocean.com/api](https://spotter.sofarocean.com/api), but this will invalidate all previous tokens.

The Wave Spectra API and the Spotter & Smart Mooring API both accept a valid API token either as a `token` in the request HTTP header or in the `token` query parameter.
