CONVERSIONS API

Fix CAPI so every purchase and lead event actually matches.

You set up CAPI. EMQ is still at 3. Purchase events and lead conversions barely match to real users. Here is how to fix it.

Identity-enriched events. Browser-server deduplication. First-party domain tracking. EMQ from 3 to 7+.

CustomerLabs Conversions API — identity-enriched server-side delivery with browser-server deduplication and first-party domain tracking improving EMQ from 3 to 7+ CustomerLabs Conversions API — website events (product viewed, added to cart, checkout, purchased) delivered server-side to Meta, Google Ads, TikTok and Snapchat

WITHOUT THIS

Basic CAPI is a pipe. It doesn't fix the signal.

Thin identity, duplicate events, and third-party cookies. Meta's algorithm still struggles to match.

01

Duplicate events inflate your numbers

Browser pixel and server both fire. Meta sees two purchases. Conversion count is wrong.

02

Identity context is too thin

You send hashed email. Meta needs email + phone + fbp + fbc + external ID. Thin identity = low EMQ.

03

Signal quality degrades silently

EMQ drops from 6 to 3 over weeks. Nobody notices until ROAS tanks.

Why CustomerLabs wins here

CustomerLabs goes beyond a basic CAPI pipe by improving delivery quality, identity continuity, and downstream signal logic at the same time.

HOW IT CONNECTS

Browser + server events → deduplicated → enriched → delivered

HOW IT WORKS

Better CAPI in three steps. No migration needed.

Sits between your event sources and Meta's CAPI endpoint. Existing setup keeps working.

Connect

CustomerLabs ingests your browser and server events. No need to remove existing pixel or CAPI setup.

Deduplicate

Browser and server events are matched and deduplicated. Meta sees one clean event per action.

Enrich

Every event is enriched with the full identity profile — email, phone, fbp, fbc, external ID.

Deliver

Events sent server-side through a first-party domain. Higher trust score. Higher EMQ.

DELIVERY QUALITY

EMQ improves because the signal is better

Identity depth, deduplication, and domain trust.

Full identity on every event

Not just hashed email. Email + phone + fbp + fbc + external ID on every event.

Browser-server deduplication

One purchase, one event. No inflated counts.

First-party domain delivery

Events arrive from your domain. Meta trusts first-party signals more.

CAPI delivery quality — identity enrichment improving EMQ score

IDENTITY CONTINUITY

The conversion carries the click context

Conversions map back to the original ad click.

Click IDs persist to conversion

fbclid from the ad click is still attached when the purchase fires.

Cross-session identity

Click Tuesday. Purchase Saturday. Identity context stays across sessions.

EMQ monitoring

Track EMQ trends. Know when signal quality drops before campaigns suffer.

Identity continuity — click IDs persisting from ad click to conversion

WHAT THIS UNLOCKS

With better CAPI quality, you can:

Higher EMQ means Meta learns from more of your conversions.

Get EMQ From 3 To 7+

Dundas Life did it. Full identity + dedup + 1P domain. CPL dropped 67%.

CPL Drop — Dundas Life dropped cost per lead 67% with identity, deduplication, and first-party domain

Recover From iOS Tracking Loss

Server-side signals compensate for browser loss. Campaigns learn from real conversions.
