    How do I pass a value in a URL to populate a field in my form?

    Asked by taxproez on July 13, 2017 at 04:20 PM

    I am doing some split testing to test various landing pages. I would like to pass a value to a hidden field, so I can track the success of each landing page.

    You can use Field Prepopulator app. Here's the link: http://prepopulate.jotform.io/.

    If you want to do it manually, please check this guide: Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters.

    Hope that helps. Let us know if you need further assistance. Thank you.
