In Google Tag Manager (GTM), the language of the Cookiebot consent banner can be controlled by a GTM variable, e.g. a fragment of the current URL on the website.
We assume that you have already implemented the Cookiebot CMP tag in GTM.
While this can be achieved in multiple ways, you may for example create a Custom JavaScript Variable named "Current Language" that returns a two-letter ISO language code based on custom logic. In this example, the language is set to either French or Spanish and will default to English, depending on the path of the URL that the user is currently visiting on your website:
function()
{
var currentUserPagePathname = location.pathname.toLowerCase();
var currentUserPageCulture = "en"; //default to English
if (currentUserPagePathname.indexOf("/fr")==0)
{
currentUserPageCulture = "fr";
}
else if (currentUserPagePathname.indexOf("/es")==0)
{
currentUserPageCulture = "es";
}
return currentUserPageCulture
}
Once saved, add the variable to your Cookiebot CMP tag in GTM by setting the "Language" dropdown to "By GTM Variable" and select the {{Current Language}} variable.

Hi Jacob,
Thank you for your documentation!
What should I write in currentUserPagePathname.indexOf(" ") if I want English to be displayed on my mydomain.com root domain, while German to be displayed on my de,mydomain.com subdomain?
Kind regards,
Ilya
