Conversion API
Definition
What is Conversion API?
Server-to-server tracking that sends conversion events directly from your server to ad platforms (Meta CAPI, LinkedIn CAPI, Google Enhanced Conversions). Bypasses iOS 14, Safari ITP, and ad blockers that broke client-side pixels. Required for accurate attribution in 2026.
