GTM template: WordPress e-commerce tracking with GTM4WP & GA4

The WordPress plugin GTM4WP pushes e-commerce events into the dataLayer for you. What’s almost always missing is the other half — the piece inside GTM that picks those events up and sends them to GA4. That’s what this template is: one GA4 event tag and 18 dataLayer variables for complete e-commerce tracking.

What’s in the template

1 GA4 event tag

A single tag that reacts to every GTM4WP e-commerce custom event — from view_item through to purchase.

18 dataLayer variables

Every e-commerce parameter GA4 needs:

1 custom event trigger

Fires on all GTM4WP e-commerce events: view_item, add_to_cart, begin_checkout, purchase, and the rest.

Prerequisite: the GTM4WP plugin

The GTM4WP plugin has to be installed and configured:

1. Install and activate the plugin
2. Enter your container ID
3. Under Integration → WooCommerce: enable “Track Enhanced E-Commerce”
4. Set the dataLayer format to GA4

Setup

1. Import the template

Import container → upload the JSON → merge.

2. Enter your GA4 measurement ID

Put your G-XXXXXXX ID into the GA4 event tag. The e-commerce parameters are pulled from the dataLayer variables automatically.

3. Test it

1. Turn on GTM preview mode
2. Walk the shop: view a product → add to cart → checkout → buy
3. Check GA4 DebugView: are view_item, add_to_cart, begin_checkout and purchase arriving?

Why one tag for everything

GTM4WP writes the event name straight into the dataLayer, and the tag takes it over as the GA4 event name — so you don’t need a separate tag per event. That keeps the container lean and maintainable.

The configurator that generates this container is here: GTM configurator. The JSON it produces is language-neutral, so it works the same in any container.

Grab the container file below and import it into your Google Tag Manager container under Admin → Import Container. No sign-up, no email wall — it’s a plain file.
