Main Domain Cookie

With JENTIS, you can easily capture complete user journeys across all your subdomains. The Main Domain Cookie feature allows you to configure whether first-party identifiers (f.e. JENTIS User-ID) are implemented at your website’s main domain or subdomain level in your containers. With just one click, all data can be shared across the main domain and all its subdomains, ensuring consistent user sessions, unified tracking, and a clearer understanding of how users engage with your entire digital ecosystem.

In this article, we’ll explain how to configure this when creating or editing a container, how to verify if the JENTIS cookie is set on your main domain or subdomain, and how to configure it.
