# Authentication

> Authenticate your API requests securely using API tokens.

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, please reach out to [support@userpilot.com](mailto:support@userpilot.com) for regenerating it.
