# Authentication

## Overview

The Dromo API uses API keys to authenticate requests. You can view and manage your API keys in the [Dromo Dashboard](https://dashboard.dromo.io).

<Warning>
  **Keep your backend API keys secure!**

  * Never expose them in client-side code
  * Store them securely in environment variables
</Warning>

## Authentication Methods

To send an authorized API call, include your backend API key in the `X-Dromo-License-Key` header.

<CodeGroup>
  ```bash cURL theme={null}
  curl -H "X-Dromo-License-Key: YOUR_API_KEY" \
        https://app.dromo.io/api/v1/schemas
  ```

  ```javascript JavaScript theme={null}
  const response = await fetch('https://app.dromo.io/api/v1/schemas', {
    headers: {
      'X-Dromo-License-Key': 'YOUR_API_KEY',
      'Content-Type': 'application/json'
    }
  });
  ```
