To track the lead sce data on all your Jotfrom forms, simply add the following html code at the beginning of your Jotform embed code (iframe):

data-leadsources-iframe

So if your iframe looks like this:


    <iframe
      id="JotFormIFrame-123456789"...

Edit it like that:


    <iframe data-leadsources-iframe
      id="JotFormIFrame-123456789"...
