The Conversions API sends conversion events from your server to Meta, so fewer sales go unreported.

How does CAPI work?
Your server (or a service like Stape) sends purchase and lead events to Meta alongside the browser pixel; deduplication stops double counting.
Why does CAPI matter?
Browsers block a growing share of pixel events. CAPI restores the signal, which usually improves optimisation and lowers cost per purchase.
