Google Tag Manager & CookieTractor

Google Tag Manager (GTM) is a tag manager from Google that is used to trigger scripts and tags on a web page. Here are instructions on how to set up GTM to adapt to user selections in CookieTractor.

Setup CookieTractor with GTM

To control which of your scripts belong to the respective cookie category, the scripts need to be categorized. CookieTractor has built-in support for Google Tag Manager and will trigger events based on the visitor's consent settings. To use these inside Google Tag Manager, we need to create "Triggers" for any "Tags" dependent on the consent settings.

If you want to import all triggers and variables instead of creating them yourself, you can find instructions below.

Create the following triggers inside your Google Tag Manager account:

Name	Trigger Type	Event Name
Consent - Necessary (All Pages)	Custom Event	cookies_necessary
Consent - Functional (All Pages)	Custom Event	cookies_functional
Consent - Statistical (All Pages)	Custom Event	cookies_statistical
Consent - Marketing (All Pages)	Custom Event	cookies_marketing
Consent - Undefined (All Pages)	Custom Event	cookies_undefined

Now, update any Tags that require consent from your users to be triggered by any of these Triggers.

Note that CookieTractor supports Google Consent Mode, services that support this technology should continue to go against "All Pages" in Google Tag Manager.

If you need to listen to events when a user revokes a consent, you can create the following Triggers and use them on your Tags:

Name	Trigger Type	Event Name
Consent Revoked - Functional (All Pages)	Custom Event	cookies_revoked_functional
Consent Revoked - Statistical (All Pages)	Custom Event	cookies_revoked_statistical
Consent Revoked - Marketing (All Pages)	Custom Event	cookies_revoked_marketing

Variables to check for consent

In some cases, one might need to check if a visitor has consented to a specific type of cookie using "Conditions" in Google Tag Manager. To make it easier to access this information, we can add User-Defined Variables to get this information. In Google Tag Manager, go to "Variables" and add the following:

CookieConsent_AllowFunctional

Name: CookieConsent_AllowFunctional
Type: Custom Javascript
Code:
function(){
return cookieTractor.consent.contains('functional');
}

CookieConsent_AllowStatistical

Name: CookieConsent_AllowStatistical
Type: Custom Javascript
Code:
function(){
return cookieTractor.consent.contains('statistical');
}

CookieConsent_AllowMarketing

Name: CookieConsent_AllowMarketing
Type: Custom Javascript
Code:
function(){
return cookieTractor.consent.contains('marketing');
}

Import settings

You can import this JSON-file into Tag Manager, under Admin/Container/Import Container.

Unzip the downloaded file, and select the JSON-file as the file to import
Select your existing/current workspace
Choose Merge to append the settings, rather than to replace them
Check that everything looks correct, and continue by confirming the changes

The file contains all triggers and variables mentioned above. Please be careful though, an import with override will delete all current settings in the container.

Rename the data layer

Google Tag Manager supports renaming the data layer to use another variable name than the default "dataLayer". For CookieTractor to be able to communicate with Google Tag Manager our script tag needs to be updated to indicate the new data layer name.
