Add Facebook Conversion API

There's a new module https://www.drupal.org/project/meta_conversions_api →

Doesn't support Drupal Commerce yet.

I saw your issue regarding the Simple Facebook Pixel module. It's a known challenge with some setups, where the module might not support all the new tracking requirements.

For many sites, a good solution is to move away from client-side tracking and use the Facebook Conversions API (CAPI). It's a more reliable way to send conversion data directly from your server to Facebook, which helps with browser limitations and ad blockers. You can find some useful info on setting up a CAPI gateway here: https://stape.io/fb-capi-gateway.
