I'm trying to track what transactions are coming from social media advertising campaigns, however due to the set up of our existing site (Magento) which goes through a Paypal gateway. All transactions seem to be originating from Paypal.
I need to figure out a way around this, I've tried to set up a goal that works using complete check out and segments as well but cannot seem to break down which social media platform is responsible for these sales.
I also need to be able to see the transaction ID inside the eCommerce tab of Google Analytics.
