The way in which Google Analytics works is to record the URL from which the user arrives at your site. As all transactions occur on the PayFast site, before the user is redirected to your site, all that Google Analytics can see is PayFast. This, unfortunately, means that it is not possible to record on Analytics where the payment came from or the amount, as all that Google is looking for is the URL.
Can I get more from Google Analytics regarding PayFast?
