CAPI
Conversions API (CAPI)
Sending conversions directly from your server to the platform (Meta, TikTok, Google), server-to-server, instead of relying only on the browser pixel. It recovers conversions lost to ad blockers and browser restrictions and improves matching.
- Why it matters
- The browser pixel alone loses 20-40% of signal. CAPI plus server-side collection closes that gap — directly into the quality Smart Bidding sees.
