Add event_id parameters to GA4 tag
When you want to send an event to your Meta Events Manager via Server-Side Tagging, you need to add an event_id as a parameter to the GA4 event tag in addition to a Facebook Pixel tag. This GA4 event tag is sent to the server, and from the server, it is sent to Meta. Meta receives a browser event from the Facebook Pixel tag on the web container and a server event from your sGTM container. Both events must have the same event_id to deduplicate correctly.
Open a GA4 event Tag
Select the Tag Configuration
Add a new parameter at the bottom of the event parameters.
As the event parameter (left), enter “event_id”. As the value (right), enter the event ID variable.
Don’t have an event ID variable yet? At the bottom of this helpdesk article, you can find how to add it to your web container.
Save the tag.
Ensure that your Facebook Pixel tag with the same event name and trigger has the same event ID variable filled in under ‘More Settings’.
Within your container, go to "Templates"
Click "Search gallery"
Search for "Unique ID"
Select the variable template that appears and click on ‘Add to workspace’.
