Conversions API
CAPI
Meta's server-side tracking solution sending conversion data directly from your server to Meta, bypassing browser limitations from iOS 14 and ad blockers.

Formula:
Server-to-server event tracking

Benchmarks
Event Match Quality: 7-9 with CAPI vs 3-5 Pixel-only. CAPI captures 130%+ more data than Pixel alone.
—————————————
Why It Matters
CAPI is now essential, not optional. Browser-based Pixel misses 30-50% of conversions due to iOS opt-outs (88-96% opt out) and ad blockers. Implement CAPI alongside Pixel for redundancy. Higher Event Match Quality = better targeting.
