E-commerce Developer: Shopify, GA4/Meta Tracking Fixes

We have a Webflow storefront connected to Shopify checkout and are experiencing tracking gaps and inaccurate data in GA4 and Meta.

This is not a Shopify "bug" but a missing implementation.

We are looking for a freelancer with strong Webflow, JavaScript, GTM, GA4, and Shopify experience to implement proper client-side and server-side tracking.

• Webflow Front-End Events Missing in GTM

What is happening

Key ecommerce interactions from the Webflow storefront do not appear in Google Tag Manager, including:

Add to cart

Cart drawer interactions

Checkout clicks

Why this happens

Webflow does not push ecommerce events to dataLayer by default

GTM can only track events that are explicitly pushed via JavaScript

Our product, cart, and checkout elements are custom Webflow components

Shopify tracking apps cannot detect these events because they are outside Shopify's theme

What needs to be done

A front-end developer must:

Add () calls in Webflow for key events, such as:

view_item

addtocart

removefromcart

begin_checkout

Ensure correct event parameters (product ID, name, price, quantity, currency)

Validate events firing correctly in GTM Preview and GA4 DebugView

This is an unimplemented requirement, not a bug.

• Inaccurate Purchase Tracking in GA4 & Meta

What is happening

GA4 and Meta show different and inaccurate purchase numbers compared to Shopify

Purchases may fire late, twice, or not at all

Why this happens

Browser-based tracking is unreliable in a Webflow → Shopify checkout flow

Redirects, Shop Pay, consent banners, and ad blockers break client-side purchase events

Shopify GA4/Meta apps are built for Shopify themes, not external front-ends

What needs to be done

A backend / analytics developer must implement server-side purchase tracking:

Listen to Shopify orders/paid webhook

On confirmed payment:

Send purchase event to GA4 via Measurement Protocol

Send purchase event to Meta via Conversions API

Ensure deduplication using order ID

After verification, disable browser-based purchase tracking from Shopify apps to prevent duplicates

Contract duration of less than 1 month. with 30 hours per week.
