We urgently need to have build by default, or the option to manually add the "form_start" and "form_submitted" events in the GHL native forms.
I've spend 2 hours in a meeting yesterday with the GA4 team from Google trying to configurate the "form_start" and "form_submitted" events from the GHL native Form without any success. I've to appeal to CF7 on WordPress to get this working but it's not practical and that also force us to use Zapier etc...to ensure these leads are pushed to the CRM.
Google is "forcing" all advertisers to use the enhanced conversions to ensure they'll get the best results on the Ads by allowing GA4 to collect behavior data, and unfortunately this is not possible with GHL Forms or funnels. Below is the link from Google with more details and attached is the exact event table that needs to be included in the GHL Forms ASAP.
