@TealiumJustin Thanks for your reply and the screenshot. Very clear and helpful! Do we still need to register this parameter at GA4 UI as dimension as well ? (It seems if we use Google tag manger, we need to register custom parameter in GA4 from UI as dimension ) BTW I also try to sent a custom event to GA4. So, here is the case: When I search from home page, I can reach to a search results page.Data layer variable is "page_name", value is "search results", and then I can name the event as "Search_from_homepage" and send this event to GA4 right? I saw purple varables "clean_page_name", and "page_name". Which one I should select? Thank you very much!
