Meta’s Conversions API (CAPI) was designed to fix what the pixel couldn’t—by sending server-side events directly to Meta, bypassing browser blockers, ITP, ad blockers, and cookie loss. But in reality, most brands implementing CAPI face a new set of challenges: duplicate events, misaligned schemas, and low event match quality that actually worsen attribution instead of improving it.

Bily solves this with surgical precision. At its core is a declarative mapping layer that takes raw checkout data and restructures it into Meta-validated payloads. It intelligently deduplicates against any overlapping pixel events, ensuring that Meta receives a single, clean record of truth—never overcounted, never rejected.

This clean feed pays off immediately. Event match quality scores rise. Conversions attribute faster. Learning phases shorten. CPMs drop as Meta’s auction confidence grows. And remarketing audiences refresh in real time, instead of relying on stale browser-side signals.

The end result is clarity. Budget decisions align with true performance, not partial guesses from a broken browser. With Bily powering Meta’s CAPI, marketers finally close the loop between action and attribution—accurately, efficiently, and automatically.
