CodexFit dataLayer event reference (V3 to V4)

This reference lists the events and fields on your site's data layer (window.dataLayer), so you can configure GA4 and your tag manager from what the site actually sends. It covers the move from the previous (V3) event names to the current GA4-aligned names, the purchase fields, and the events and properties available for custom dimensions.

1. Event names, then and now

If your tag manager was built against the previous event names, here is how they map to the current ones.

During the transition, both names are sent for each event, so your existing setup keeps working while you migrate:

• sign_up is sent alongside the previous customerRegistered
• add_to_cart alongside the previous addToCart
• login alongside the previous customerLogin
• purchase keeps the same name and carries both the current fields and the previous ecommerce block on the one event

So you can build triggers on the current names now, and your existing container keeps working untouched until you are ready to switch over.

2. Purchase fields

On the purchase event, at the top level:

Please note: value is the sum of item list prices (including the recurring plan price for memberships), following the GA4 convention. It is not the same figure as the gross amount paid you may have read before. If you need that, it is on the same event under the previous ecommerce block:

• ecommerce.currencyCode

• ecommerce.purchase.actionField.id (transaction id)

• ecommerce.purchase.actionField.revenue (gross, including tax and any ongoing amount)

• ecommerce.purchase.products[]

3. Events and properties for your GA4 custom dimensions

Standard GA4 events (GA4-named):

purchase, add_to_cart, remove_from_cart, view_item, view_item_list, select_item, view_cart, begin_checkout, add_payment_info, sign_up, login, registration_start, registration_step1 (registration_step2 and so on for multi-step forms)
