Google Tag Manager: integration, data and consent

Google Tag Manager is an API or third-party technical service integrated into the website. The data exchanged and applicable requirements depend on the feature and configuration being used.

When Google Tag Manager uses tracking technologies or processing that requires consent, tarteaucitron can condition its activation on the visitor’s choice.

Managing Google Tag Manager with tarteaucitron

When Google Tag Manager is integrated through tarteaucitron, its activation is managed according to the visitor's consent choice. The service can therefore be loaded only when the corresponding permission has been granted and the visitor can later change this choice through the consent interface.

The current tarteaucitron integration declares 22 cookies associated with Google Tag Manager:

Configuring Google Tag Manager

Add the following code to your website after initializing tarteaucitron. Replace the example values with those provided by Google Tag Manager.

<script>
tarteaucitron.user.googletagmanagerId = 'GTM-XXXX';
(tarteaucitron.job = tarteaucitron.job || []).push('googletagmanager');
</script>

Additional code

The following code can already be present on your website and should be kept where the service is used.

<script>tarteaucitron.user.googletagmanagerCustomDomain = 'custom.domain/path';</script>

Code to remove

Default HTML code to remove from your website:

<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src= '//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f); })(window,document,'script','dataLayer','GTM-XXXX');</script>

Frequently asked questions about Google Tag Manager

Does Google Tag Manager require consent?

The API name alone is not enough to determine whether Google Tag Manager requires consent. The data transmitted, technologies used and purpose of the service must be considered.

How does tarteaucitron block Google Tag Manager?

tarteaucitron controls the activation of Google Tag Manager according to the consent choice recorded for the visitor. The service code is triggered through tarteaucitron instead of being loaded independently from the consent manager.
