Prestashop Facebook Conversions API Setup

I need my Prestashop store fully connected to Facebook through the Conversions API so I can rely on server-side data rather than just the browser pixel .The store is already live with a standard Pixel, but events are inconsistent and match quality is low.

What I’m after: a clean end-to-end CAPI implementation, followed by a health check of my Commerce Manager account—specifically the Data Sources section and the overall event match rate. If you spot configuration issues while you’re in there, I want them fixed.
