I ask this question because I wanted to set up Google Analytics tracking with Google Tag Manager using Google Tag Manager extension for Magento.
To do so, I had to unable GA in Magento (GA API).
However I figured out that Magento manages both GA and GA ecommerce tracking at the same time through the GA API.
And as Google Tag Manager doesn’t support the GA ecommerce tracking yet, I ended up being unable to use Google Tag Manager for Google Analytics tracking…
I have included the Adwords conversion tag as well as the Google remarketing tag in Google Tag Manager.
Does anyone know if it’s safe. I mean if it will work properly (because I can’t really test it) with Magento?
