Is it possible to change the site address after submitting the form using this one field as a utm tag?

Question

JavaScript

I came up with the idea to make an input form where a person enters data: full name, number, promo code, and the script substitutes the entered promo code data as utm in the link (in fact, sends it to our website with its promo code entered) we can track the transition data in the metric and roistate.

Answer 1

yes, I do.
you form a new url based on the form data and do
window.location.href = received link;
