# Authentication

> Userpilot APIs use API tokens to authenticate requests. You can view and manage your API key in the Environment Page of your Userpilot dashboard.

Userpilot APIs use API tokens to authenticate requests. You can view and manage your API key in the **Environment Page** of your Userpilot dashboard.

## How to Use Your API Key

Include your API key in the `Authorization` header of every API request:

```http theme={null}
-H 'Authorization: Token {{API_KEY}}'
```

<Warning>
  Your API key carries many privileges. Keep it secure and do not share it in publicly accessible areas.
</Warning>

## Where to Find Your API Key

1. Log in to your Userpilot dashboard.
2. Go to the **Environment Page**.
3. Copy your API key from the API Key section.

<Note>
  All API requests must be made over HTTPS.
</Note>

## Security Best Practices

* Never expose your API key in client-side code or public repositories.
* Rotate your API keys regularly.
* If you suspect your API key has been compromised, regenerate it immediately from the dashboard.
