To enable tracking, just create a tag with Google Analytics and in a view associated with the tag enable enhanced ecommerce as follows:
Then copy and paste your Tracking ID which is of the form UA-XXXXXXXX-X into the frontoffice settings in your backoffice, under frontoffice settings > tracking
That's it! You should now find that when you log into Google Analytics that you see pageviews and access enhanced ecommerce reporting.
