CONVERSIONS API SETUP

Send the conversions ad blockers and iOS won’t let through

We configure Server-Side Conversion APIs to send event data directly from your web server to ad networks — bypassing ad blockers, browser privacy restrictions, and iOS tracking limitations for maximum reliability.

The problem

Browser-only tracking is losing more data every year

iOS privacy restrictions, ad blockers, and cookie-blocking browsers all sit between your Pixel and the conversions it’s supposed to record. The result: ad platforms optimize on an incomplete picture, and campaigns that look underperforming may actually be working better than the data shows.

Meta’s own reported data shows pairing Pixel with Conversions API cuts cost per result by 17.8% — not because CAPI creates new conversions, but because it recovers the ones the browser was already losing, giving the algorithm a fuller, more accurate signal to optimize against.

What we do

Server-side event sending

Conversion events sent directly from your server to ad platforms, independent of what the visitor’s browser blocks.

Bypasses tracking restrictions

Data reaches ad platforms regardless of ad blockers, ITP, or iOS App Tracking Transparency limitations.

Deduplication built in

Server and browser events matched by unique event ID, so nothing gets double-counted in your reporting.

Improved match & attribution

More complete data means better audience matching, more accurate attribution, and lower acquisition costs.

How we do it

Configured, deduplicated, verified

01

Audit current tracking

We review your existing Pixel setup and identify exactly which events need server-side backup.

02

Configure server-side events

Events sent from your server to each ad platform, matched to the same actions your Pixel already tracks.

03

Deduplicate precisely

Unique Event IDs matched between browser and server events, so nothing gets double-counted.

04

Verify match quality

Event match quality checked in each platform’s Events Manager, confirming the data is actually improving delivery.

Tools we use

Meta Conversions API · TikTok Events API · Google Enhanced Conversions · Server-side Google Tag Manager · Stape / CAPI Gateway tools

Timeline: a standard CAPI setup for one or two platforms is usually complete and verified within 3–5 business days; multi-platform setups with server-side tag management can take a little longer depending on your existing infrastructure.

Why BetterSell

Server-side data done precisely, not bolted on

Deduplication done right. Server and browser events are matched by Event ID, so your numbers stay accurate, not inflated.

Match quality verified. We check Events Manager match quality scores, not just assume the setup is working.

Built for your actual events. CAPI is configured around the events that matter to your business, not a generic template.

Documented handoff. You get a clear record of what’s sending server-side and how, so your team isn’t locked out of it.

CAPI recovers data your Pixel is already trying to send

Conversions API works best paired with a correctly installed Pixel and clean event tracking underneath it. If those aren’t solid, CAPI just duplicates the same gaps server-side.

Recent results

What this looks like in practice

Cost per result, cut

Before: Running Meta ads on Pixel-only tracking, with rising cost per result and no clear explanation why.

Diagnosis: iOS tracking restrictions meant the Pixel alone was missing a meaningful share of real conversions, so the algorithm was optimizing on incomplete data.

Fix: Installed Conversions API alongside the existing Pixel, deduplicated events by Event ID, and verified match quality in Events Manager.

Result: Cost per result dropped within the following weeks, in line with Meta’s own reported impact of pairing Pixel with CAPI.

Match quality, improved

Before: Event match quality sat well below the recommended threshold, limiting how well Meta could match conversions to real users.

Diagnosis: Customer data being sent server-side wasn’t hashed and formatted to Meta’s specification, so much of it was being discarded.

Fix: Corrected the hashing and formatting of customer data parameters sent through Conversions API.

Result: Event match quality score climbed into the recommended range, improving audience matching and campaign delivery.

Multi-platform, unified

Before: Running ads on Meta, TikTok, and Google separately, each with inconsistent or missing server-side tracking.

Diagnosis: Each platform’s tracking had been set up at different times by different people, with no consistent event structure between them.

Fix: Standardized event tracking and implemented CAPI/Enhanced Conversions consistently across all three platforms.

Result: All three platforms began receiving consistent, deduplicated conversion data, improving reporting accuracy across the board.

Here are some frequently asked questions

What people mostly ask us about CAPI setup and what you might wanna know –

It sends conversion events directly from your server to ad platforms, bypassing browser-based tracking restrictions like ad blockers and iOS limitations.

No, it works alongside your Pixel — the two are deduplicated so you get the most complete picture without double-counting.

Server-side event configuration, deduplication logic, hashed data matching, and match quality verification — see the full scope above.

Meta Conversions API, TikTok Events API, and Google Enhanced Conversions are the most common, depending on where you advertise.

Meta’s own data shows a 17.8% average reduction in cost per result when Pixel and CAPI are paired correctly — results vary by account.

We handle the technical implementation, including server-side tag management where needed, so you don’t need in-house development resources.

Events are matched by a unique Event ID shared between the browser and server, so each platform can identify and remove duplicates.
