Why can't I just do this myself?

You can — if you have 80–120 hours to learn server-side GTM, debug iOS dedup edge cases, and stress-test EMQ across every conversion event. We do it in 7–10 days because we've done it 300+ times.

What if it doesn't work?

Two protections: (1) 95% tracking accuracy guarantee — we keep working free until your Meta Match Quality hits 8+. (2) You own the entire stack — server, container, runbook — on your accounts from day one.

Will Apple / Google break this in the future?

1st-party server-side tracking is what survives Apple, Mozilla, and Chrome cookie deprecation. The CAPI / Events API endpoints we use are how Meta, Google, and TikTok publicly committed to keeping the channel open.

Yes — works as island components.

Headless E-commerceFor headless storefronts

Get your Headless E-commerce tracking to 95%+ accuracy guaranteed in writing.

Headless storefronts have no native pixel apps, no Customer Events API, no marketplace plugin to lean on. Most teams ship a half-broken GA4 install and a Meta Pixel that fires twice on hydration. We ship a typed React/Vue dataLayer module + server-side CAPI gateway that runs on edge runtimes and survives every deploy.

Why headless breaks tracking, and how it should be rebuilt

Headless removes the two things most tracking implementations quietly rely on: a full page load per step, and a template you can drop a script into. Nothing about the tracking survives that unchanged.

1
Route changes replace page loads
In a single-page app, navigation does not reload the document. Tag firing has to be driven by the router, deliberately, or you get one page view per session and nothing else.
2
The data layer is pushed from the application, not scraped
There is no server-rendered markup to read values out of. Product, cart and order data must be pushed by the application code at the right moments — which makes tracking a development dependency, not a marketing task.
3
Checkout often lives on a different origin
A hosted checkout on another domain breaks cookies, sessions and referrer. The session identifier has to be carried across explicitly.
4
The purchase is confirmed server-side
In a headless build the order is created by an API call. That response, or the backend webhook it triggers, is the only reliable purchase trigger. A confirmation route can be reloaded, shared, or never reached.
5
A server container becomes close to mandatory
It gives you one place that holds the order truth and fans it out, rather than trying to reconstruct a purchase inside a client application that may already have navigated away.

Headless E-commerce · events

Event triggers in a headless build

The trigger is the hard part. The event names are ordinary; what changes is what you are allowed to hang them on.

Event	Trigger in a headless app	Source of data
page_view	Router navigation complete, after the view renders	Route metadata
view_item	Product query resolves for the product route	API response, not the DOM
add_to_cart	Cart mutation returns success	Mutation response
begin_checkout	Checkout session is created	Checkout API response
purchase	Order confirmation from the backend or its webhook	Order API or webhook — never the confirmation route alone
refund	Backend refund webhook	Backend only; no client is present

Headless E-commerce · diagnose

Where headless tracking usually fails

01
Check whether route changes fire anything
Navigate through several views and count the events. One page view for the whole session is the classic symptom.
02
Test the purchase trigger against a reload
Reload the confirmation route. If a second purchase fires, the trigger is the route, not the order.
03
Follow the session across the checkout origin
Confirm the identifier and click IDs survive the hop to a hosted checkout and back.
04
Confirm the data layer carries real values
In a headless build the values must be pushed. Empty or placeholder values reaching the platforms are common and invisible in the count.
05
Check hydration timing
Tags that fire before the application has hydrated read undefined values and send them anyway.
06
Reconcile against the backend
One closed week, matched on order ID. Headless setups usually read low, and the size of the gap tells you which trigger is failing.

Proof for a headless build

Source of truth

Backend or commerce API order records

Route navigation produces one page view per view, verified across a multi-step journey.
Reloading the order confirmation route produces no additional purchase event.
Session and click identifiers confirmed surviving the checkout origin hop.
Purchase count within a few percent of backend orders for a fully closed week, matched on order ID.
No purchase event carrying placeholder or undefined values.
A written record of which application code paths own which events, since these will break the next time the frontend is refactored.
