# Overview

> Learn how to authenticate with the Longwave API.

The Longwave API is a REST API that uses bearer token authentication.

Base URL for API requests:

```
https://api.longwavehq.com
```

## Getting your API key

<Info>
  The Longwave API is in private beta. Please [contact
  us](mailto:support@longwavehq.com) for access.
</Info>

1. Sign in to the [Longwave dashboard](https://app.longwavehq.com).
2. Open **Settings** and create an API key. Copy and store it securely; it may
   be shown only once.
3. Send the key on every request as a `Bearer` token in the `Authorization`
   header.

<Warning>
  Your API key is sensitive. Treat it like a password: don't share it, don't
  commit it to source control, and don't paste it into client-side code. If a
  key is exposed, rotate it immediately.
</Warning>

To rotate or revoke a key, return to the same place in the dashboard.
