I'm trying to understand how the GA integration functions. I'd like to be able to pass UTMs through to GA and hopefully, eventually Marketo.
Has anyone been able to pass UTMs through thinkific to GA?
Has anyone been able to use zapier and "zap" hidden fields through? Specifically UTM?
Is there any Segment/thinkific/Marketo example out there?
You should be able to do what you're looking to do by setting up our Google Analytics integration for your site. More on that here
Once you've done that, I believe the rest of the setup for the UTMs is on the Google Analytics side - more on that here.
For your other questions, if you can send over a little more info on what you're looking for here then I'll be happy to advise!
