Google Tag Manager, Ads, and dataLayer

-- HikaShop version -- : 4.0.0
-- Joomla version -- : 3.9.12
-- PHP version -- : 7.2

I have been working to implement Google Analytics Conversion Tracking on a site through GTM (Google Tag Manager).

GTM does the dirty work placing all the GA tags, Ads tags, and others. It all seems to be working but I don't think I have the conversion part correct.

In the documentation for GTM Ecommerce, there's steps to use Data Layer. The dataLayer object contains and passes information from the website, product data, transaction data. It seems I should be able to see this data in the browser console but I could not find it when testing some checkouts.

There's a plugin & documentation for HikaShop to integrate with Google Analytics which notes "Also, this plugin is for the e-commerce data of Google Analytics" - If the plugin is enabled & filled, is the dataLayer taken care of, or do I need to modify the order confirmation page (or other pages) ?

I tried searching the forum for similar questions. The most recent was over 2 years ago and I don't think they were using GTM, just adwords. Hoping you can offer some guidance. Thank you!

Thank you for clarifying the documentation. If I am successful I will share my changes here in case anyone else is attempting as well.

Hi Itsyourit.
Did you find a way to get the dataLayer objects working for hikashop?

Sadly no I did not manage to solve this. It was not worth it for the project to sink the time into writing and testing custom code.
