# Introduction to POS Settings

> Retrieve configuration settings for your POS integration

Settings endpoints allow you to retrieve configuration details for your POS system integration with ClearLine. This includes enabled features, marketing preferences, loyalty program configuration, and integration-specific settings.

## What are POS Settings?

POS settings contain the configuration data that controls how ClearLine integrates with your specific POS system. These settings help you:

* **Feature Detection:** Determine which ClearLine features are enabled for your location
* **Loyalty Configuration:** Get loyalty program rules, point values, and reward tiers
* **Marketing Preferences:** Retrieve display options and promotional settings
* **Integration Parameters:** Access system-specific configuration values

## Best Practices

<AccordionGroup>
  <Accordion title="Cache Settings Appropriately" icon="database" defaultOpen>
    Cache settings for 15-30 minutes to reduce API calls. Refresh when you
    detect a configuration change or at regular intervals.
  </Accordion>

  <Accordion title="Handle Missing Features Gracefully" icon="toggle-off">
    Not all features are enabled for every location. Check feature flags in
    settings and hide/disable unavailable features in your POS UI.
  </Accordion>

  <Accordion title="Validate on Startup" icon="circle-check">
    Fetch settings when your POS system starts or connects to ClearLine to
    ensure you have current configuration data.
  </Accordion>

  <Accordion title="Don't Hardcode Configuration" icon="code">
    Always use settings from the API rather than hardcoding values. Settings can
    change without requiring a POS software update.
