# Authentication

> Learn how to authenticate your Famulor API requests using Bearer tokens. Generate API keys and securely access voice agent, lead, and campaign endpoints.

All Famulor API endpoints require authentication via API keys. Include your API key in every request using the Authorization header.

## Getting Your API Key

Follow these steps to create an API key:

1. Sign in to your account at [https://app.famulor.de](https://app.famulor.de)
2. Go to the API Keys section
3. Click "Create new API Key"
4. Save your API key securely - you won't be able to view it again

<Warning>
  Protect your API key like a password. Never expose it in public repositories,
  client-side code, or share it with unauthorized parties.
</Warning>

## Authentication Header

Add your API key to the `Authorization` header using Bearer token format:

```
Authorization: Bearer YOUR_API_KEY
```

Make sure to replace `YOUR_API_KEY` with your actual key.

## Request Example

Here's a sample cURL command showing proper authentication:

```bash theme={null}
curl -X GET "https://app.famulor.de/api/user/campaigns" \
     -H "Authorization: Bearer YOUR_API_KEY"
```

Remember to substitute `YOUR_API_KEY` with your real API key.
