I am currently trying to integrate an iframe from a partner of ours (who is driving traffic to our page). Our partner only uses the iframe for tracking purposes but is asking us to provide a unique ID for each lead. We would like to use our thank you page and a UTM field (previous page form field, hidden) to be posted back.
Knowing that the URL parameters would have to be inserted each time into the iframe - is there an easy way to script this? I have seen similar cases but not quite a working approach yet - I’m posting the iframe below as a reference.
Thank you so much in advance!!
