GTM dataLayer

The script pushes these events to window.dataLayer automatically:

Event	When
OptSensLoaded	The script finished loading
OptSensConsentReady	Consent state resolved on page load
OptSensConsentUpdate	Consent given or changed
OptSensBannerShown	Banner displayed
OptSensBannerHidden	Banner closed
OptSensPreferencesShown	Preference center opened
OptSensPageView	SPA route change (when using onRouteChange())

GTM trigger example

Create a Custom Event trigger in Google Tag Manager:

• Trigger type: Custom Event
• Event name: OptSensConsentUpdate

Use it to fire tags only after consent.

Google Consent Mode v2

Consent Mode is integrated automatically. No dataLayer work is needed for it. The script fires the default state before any Google tag runs:

gtag('consent', 'default', {
  ad_storage: 'denied',
  analytics_storage: 'denied',
  ad_user_data: 'denied',
  ad_personalization: 'denied',
  functionality_storage: 'denied',
  personalization_storage: 'denied',
  security_storage: 'granted',
});

After consent:

gtag('consent', 'update', {
  ad_storage: 'granted',            // advertising category
  analytics_storage: 'granted',     // analytics category
  ad_user_data: 'granted',          // advertising category
  ad_personalization: 'granted',    // advertising category
  functionality_storage: 'granted', // functional category
  personalization_storage: 'granted', // performance category
});

Works with Google Analytics 4, Google Ads and Google Tag Manager. See Google Consent Mode v2 for the full framework page.
