We're looking into a product called Kickfire to identify anonymous web traffic and get firmographic data appended to form fill outs. I added a script to our website footer and another script that captures form fill outs in the footer of Marketo landing pages that have a form. I thought they'd append their data directly in Marketo through a webhook but after talking to Kickfire support it seems it's a bit complicated. They now thought of a solution using the email address POST variable after a form fill out, the only problem is that we couldn't find what that variable was. Does anyone know how to get this from Marketo form fill outs?
