Why CAPI
The Meta Pixel alone isn't enough
Meta recommends server-side CAPI alongside the pixel for maximum data quality. Hello Conversions handles the server-side part automatically — no Gateway setup, no manual tokens, no code.
- iOS 14+ App Tracking Transparency bypassed
- Ad blockers can't block server-to-server events
- Meta's Event Match Quality score improves significantly
- Better Advantage+ campaign optimization with more data
- Automatic deduplication with browser pixel events

What changes when CAPI is live
Lower cost per acquisition
More conversion data means Meta's algorithm finds high-value audiences faster — reducing wasted spend.
Better audience targeting
Enhanced matching with hashed emails and phone numbers builds richer custom and lookalike audiences.
Accurate ROAS reporting
When every conversion is tracked, your reported ROAS reflects actual revenue — not a fraction of it.
