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+.
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.
Duplicate events inflate your numbers
Browser pixel and server both fire. Meta sees two purchases. Conversion count is wrong.
Identity context is too thin
You send hashed email. Meta needs email + phone + fbp + fbc + external ID. Thin identity = low EMQ.
Signal quality degrades silently
EMQ drops from 6 to 3 over weeks. Nobody notices until ROAS tanks.
CustomerLabs goes beyond a basic CAPI pipe by improving delivery quality, identity continuity, and downstream signal logic at the same time.

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.
Routing, matching, and payload control handled together.
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.
First-party domain routing strengthens attribution continuity.
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.
Delivery matters most when matching context stays strong.
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%.
Recover from iOS tracking loss
Server-side signals compensate for browser loss. Campaigns learn from real conversions.

FAQ
Common questions about Conversions API
Direct answers first.
What's wrong with my current CAPI setup?
Most CAPI setups send thin identity, don't deduplicate browser+server events, and use third-party domains. EMQ stays at 3-5.
How does CustomerLabs improve EMQ?
Three things: all available identifiers on every event, browser-server deduplication, and first-party domain delivery.
Do I need to remove my existing CAPI setup?
No. CustomerLabs works alongside your current setup. Migrate gradually.
What EMQ score should I target?
7+ is good. 9+ is excellent. Most brands start at 3-5 and reach 7+ with CustomerLabs.
Does this work for Shopify CAPI?
Yes. CustomerLabs replaces or supplements Shopify's native CAPI with richer identity, deduplication, and custom events.
