@carmendiana I don’t think it’s possible using native monday.com forms right now because you can’t prefill fields or include any custom javascript. However, you might be able to achieve this using JotForm or another 3rd party form provider which could create items in monday- see this link from jotform: How to Track URL UTM values in Jotform?
You could then integrate jotform with monday so that a new form submission creates a new item in your monday board, see here.
To do this without a 3rd party tool like JotForm would require the ability to prefill monday form fields (ideally hidden fields) based on URL parameters. That’s not possible using monday.com forms right now per this thread: but it’s a great feature suggestion which you can vote on here!
