Why Are Some Facebook Fields Not Available During Setup?

If you notice that some Facebook fields aren’t available when configuring your Facebook Ads connection, it’s likely because they are part of an action breakdown. These fields are only exposed when you select specific breakdowns during setup.

If you can’t find a field you want to sync, check whether it belongs to an action breakdown category. For example, the action_type breakdown includes fields like:

• app_custom_event.fb_mobile_complete_registration (Mobile App Registrations)
• offsite_conversion.fb_pixel_complete_registration (Completed Registration)

To learn more about the fields associated with each action, see Meta's Ads Action Stats documentation. To sync these fields, configure your connection to include the relevant action breakdown.
