pageGoogle Tag Manager (GTM)

2. Update your Facebook tags

If you're planning to keep running your existing Facebook pixels while using "Facebook CAPI" through GTM, it's really important that you update them following these guidelines. This will allow to deduplicate and keep consistent measurements of your events.

The process is straightforward as for every event you're sending via pixel tags you just need to add the event identifier - On GTM, open your "Facebook Pixel" tag and expand (14) "More Settings" to locate the "Event ID" and click (15) its icon on the right.

A new window will slide-in. Click on (16) the plus on the top right.

Click on (17) the "Variable Configuration".

Click (18) the "JavaScript Variable".

Rename your (19) variable as window.tC.uniqueEventId and set the same name in (20) the "Global Variable Name" then click (21) the "Save" button.

Back on the tag configuration, expand (22) "Advanced Settings" and (23) "Tag Sequencing" to check (24) the option "Fire a tag before Facebook Pixel fires". In "Set-up Tag", select (25) "Commanders Act | Serverside events bridge" and save your tag.

Repeat this configuration for each active "Facebook Pixel" in GTM.
