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.

  • 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.

Stop Guessed-Based Marketing.

Your competitors are losing 40% of their data to iOS privacy. By using Hello Conversions, you aren't just "fixing tracking" — you're gaining a massive competitive advantage. You will see the revenue they are missing.
