Support for Google Tag Manager's "Consent Initialization" trigger

I've created a sandbox module that does this here:

https://www.drupal.org/sandbox/jrb/3433126 →

In order for this to work, the Google Tag Manager gtag script must be included on the page by some other method. This can be done with a custom script or with a module like Google Tag → .

Just enable this module; and, when the user consents to cookies, it will call gtag with this:

gtag('consent', 'update', {
  'ad_user_data': 'granted',
  'ad_personalization': 'granted',
  'ad_storage': 'granted',
  'analytics_storage': 'granted'
});

Depending on what the maintainers of this module would like to do, this code could be folded into this module as a submodule or I could release it as a full module. Either way is OK with me.

I think probably this is the way to go? https://www.drupal.org/project/eu_cookie_compliance_gtm → which seems to connect the google_tag and eu_cookie_compliance modules. I did notice ✨ Make the module compatible with Google Consent Mode RTBC is still work in progress there though.

What you are describing in this issue is the normal behavior.

GTM fires the tag before you click Accept or Don't Accept.

"Consent Initialization - All Pages" is supposed to be the first trigger to fire. It should be used to trigger a CookieBot Tag For example.

If you want your tag to be run after the consent has been given you should create a custom event trigger matching "cookie_consent_update".
