## Best Practices

<AccordionGroup>
  <Accordion title="Use Environment Variables">
    Never hardcode your API key. Always store it securely in environment variables or secrets management systems.

    ```bash theme={null}
    export UNIFICALLY_API_KEY="your_api_key_here"
    ```
  </Accordion>

  <Accordion title="Keep Keys Secret">
    * Never commit API keys to version control
    * Don't share keys in public forums or documentation
    * Rotate keys regularly
    * Use separate keys for development and production
  </Accordion>

  <Accordion title="Handle Errors Gracefully">
    Always check for authentication errors and handle them appropriately in your application.
