I track my users behavior using Google Analytics client side. At some point the user is redirected to one of my partners and I receive a callback from the partner about the value the user has generated.
The question is: How do I append that value from the callback as a goal with a value to the users session?
The objective is to be able to get insights about which of my traffic sources generate the most value (and not just most conversions - as that could be tracked with event tracking).
The solution might be similar to this one, but I'm not sure it's still the best solution - and there could be others as well. Using Google Analytics to track the same session in client javascript and server side tracking calls?
Thanks in advance.
