I've searched around to clarify this, I'm pretty sure I can, but just want to make sure.
I want to use Google Analytics Ecommerce tracking to track hotel reservations. All I'm interested in is the total revenue associated with the transaction.
In the documentation here: https://developers.google.com/analytics/devguides/collection/analyticsjs/ecommerce
It seems to be worded as if you are required to add item objects along with your transaction object. Am I able to send just a transaction object with no items attached?
