<!-- Or use ShortCode in CMS -->
[ConsentLink beforeText="Manage your " afterText=" preferences"]

<script type="text/plain"
    data-type="text/javascript"
    data-name="analytics"
    data-src="https://example.com/tracking.js">
</script>

Consent Mode v2 Support

Support for Google's privacy-compliant tracking with consent updates.

Default Services Included

• Google Tag Manager
• Google Analytics
• Google Ads
• Microsoft Clarity

Advanced Configuration

Custom Consent Callbacks

Configure custom JavaScript for each service in Settings > Cookie Consent:

// Google Analytics example
OnAccept: if(typeof gtag === "function") { gtag("consent", "update", { analytics_storage: "granted" }); }
OnDecline: if(typeof gtag === "function") { gtag("consent", "update", { analytics_storage: "denied" }); }

// Microsoft Clarity example  
OnAccept: if(typeof clarity === "function") { clarity("consentv2", { ad_Storage: "granted", analytics_Storage: "granted" }); }
OnDecline: if(typeof clarity === "function") { clarity("consentv2", { ad_Storage: "denied", analytics_Storage: "denied" }); }

Google Tag Manager Integration

When using with lerni/silverstripe-tracking, GTM events are automatically fired based on the callbacks set in CMS:

Default Events:

• klaro-google-analytics-accepted/declined
• klaro-google-ads-accepted/declined
• klaro-google-tag-manager-accepted/declined

Setting up GTM Triggers:

1. Create Custom Event trigger in GTM
2. Use event name (e.g., klaro-google-analytics-accepted)
3. Fire your tracking tags based on consent

Configuration Override

Override defaults in your app/_config/klaro.yml:

Kraftausdruck\Models\CookieEntry:
  default_records:
    Analytics:
      Title: 'Custom Analytics Title'
      # Override any default settings
