JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
It is possible to pass data via URL, you will need to get the names of the fields that you want to pass and then add them to the link to your second form, you may do this to transfer info from a form to other one, here is a guide that will help you with that: https://www.jotform.com/help/71-Prepopulating-fields-to-your-JotForm-via-URL-parameters.
Also, this guide will help you if you want to only pre-populate some data directly in your form without changing it: http://prepopulate.jotform.io/.
If this does not help, please provide us a bit more about your workflow so we will be able to provide other ways to achieve it.
