Hi Marketo universe,
Like most of you out there, I am using hidden fields in forms to to record the utm source, medium and campaign however would like to be tracking the original UTM's along with the most recent for each of the aforementioned.
Is it possible to set a rule on the form level to allow only a one time write into a particular field? We have created a field titled utm_source_first_touch along with utm_source_last_touch to capture the respective, I just need a clean solution to map the relevant data to the first touch fields.
Any thoughts would be appreciated.
