I would like to know if it is possible to track UTM parameters directly from the Wix form without having to use a third party app
What UTM Parameters are you interested in? What do you want to do with them? What Wix form?
I know you mentioned that you want to do it without a 3rd party app, but given there has been no response I thought I’d put you to an article and associated tool that we use that works well.
