Facebook Conversion API — Complete GTM Setup + Event Deduplication (2026)
Facebook Conversion API is the most powerful way to recover lost purchase data
after iOS updates — and in this tutorial, I'll walk you through the exact GTM setup.
If your Facebook Pixel setup is missing events or your Meta Pixel and server side
tracking Facebook data don't match, event deduplication is the missing piece.
This step-by-step conversion API setup uses Google Tag Manager — no plugin needed —
so your Facebook CAPI setup stays clean, accurate, and easy to maintain.
