Trigger GTM tags based on user consent in Consent Studio
With Consent Studio, you may use a custom trigger to activate tags for your users.
In opposite to the “All pages” trigger, this method will allow tags to be loaded without requiring a page refresh. In other words, only with the custom trigger, tags will instantly be activated when the user provides their initial consent.
Adding this custom trigger can be done by creating a custom even trigger that listens to the cookie_consent_update event for a general update, or one of the category specific events:
cookie_consent_granted_functionalcookie_consent_granted_analyticscookie_consent_granted_marketing
Remember: the Consent Studio CMP tag itself should have the “Consent Initialization - All Pages” trigger at all times.
Whenever a user retracts their consent, they do need to reload the page in order to de-activate the tags that were triggered under their previous consent.
