persistent_visitor_parameters

This module checks GET and HTTP Request parameters (like utm_source, utm_medium, HTTP_REFERER) from anonymous visitors, and saves those in a cookie for further processing.

When the visitor is going further on your website and is taking some actions like doing a purchase this information can be used for analytics. It makes initial paramaters persisistent for a session.

Version 2.x

• Better integrates Registration tracking submodule to log the (UTM / Referrer / Form) source of registered users.

HOW TO USE

• Configure module here: `admin/config/persistent-visitor-parameters`
• Read already saved cookies using \Drupal::service('persistent_visitor_parameters.cookie_manager')->getCookie() inside your module, and process this data further as you need it
