Shopify Tracking & Attribution

1 Order counted once, everywhere it's advertised

2–3wk Typical setup & QA turnaround

0 Checkout events lost to Checkout Extensibility

The problem

Checkout Extensibility broke more tracking than most stores realise

Shopify moved checkout customisation into a sandboxed, script-restricted environment. Older tracking setups that relied on injecting a script directly into checkout simply stopped firing — quietly, with no error, no warning, just events that stopped arriving.

We rebuild tracking on Shopify's supported Pixels and Conversions API surface, so it survives the platform's own changes instead of breaking with the next one.

The fix

What we set up

Server-side events via the Shopify Pixels / Conversions API bridge
Checkout, upsell and subscription events reconciled against real orders
UTM and attribution surviving Shop Pay and app-based checkouts
Refunds and cancellations fed back into ad-platform reporting
Deduplication between browser and server-side events, so nothing double-counts
Consent signals respected in every event sent, not just the browser pixel

Before & after

What changes once tracking is rebuilt for Extensibility

Same store, same orders — the difference is whether the ad platform actually hears about them.

Checkout Extensibility silently breaks old pixel scripts

A script injected the old way into checkout doesn't error — it just stops running, and the gap goes unnoticed for months.

Before Breaks silently

After Rebuilt for Extensibility

Shop Pay and app checkouts lose attribution

A shortcut checkout skips the usual page flow, and with it the UTM parameters that would have credited the right campaign.

Before Attribution lost

After UTM preserved

Refunds never reach the ad platform

An order gets refunded in Shopify, but the ad platform still counts it as a full-value conversion, forever.

Before Refunds ignored

After Fed back automatically

Process

How the setup runs

Audit current tracking

What's firing, what's silently broken, and what Checkout Extensibility actually allows.

Rebuild on Pixels & CAPI

Events moved onto Shopify's supported surface, matched to real order and refund data.

QA against live orders

Checked against real checkouts, including Shop Pay and app-based flows.

Hand over and document

A written record of every event, its source and what it maps to in your ad accounts.

What clients say

Don't just take our word for it

We were told the ads were working while our accountant said otherwise. They were the first people to open the tracking and show us why both things were true at once. The reported number dropped after the fix, then grew for real.

I had no idea how much of my reporting was double counted. Now the number on the dashboard is a number I can actually plan against.

A tag manager migration from years ago had never been finished. Every signup had been counting twice, and nobody had noticed because it was consistent. Finding that paid for the whole engagement.

Questions

Common questions

Do we need to be on Shopify Plus?

No — the Pixels and Conversions API bridge is available on standard Shopify plans, not just Plus.

Does this work with Shop Pay and Shopify's accelerated checkouts?

Yes — that's specifically one of the attribution gaps this setup addresses, since shortcut checkouts are where UTM data is most often lost.

Will this conflict with apps we already use for tracking?

We audit what's currently installed first and consolidate onto one source of truth rather than layering another script on top.

Can you also build or fix our theme at the same time?

Yes — this pairs naturally with Shopify Development when both are needed.
