Is there a way to get the raw html of each field in a jotform?

Hello, 

I need to add a URL query string to each field of our form in order to pass information to the server of a donation software. Is there a way I can do this? I read that I can download the raw code, but wouldn't that mean that any changes I make to the code I downloaded won't be reflected in the form that is hosted on the JotForm site? Is there any way to accomplish this on the site or at least upload the changes I made somewhere?

Thanks!

It's not possible to add code to your form through the Form Builder, you will need to get the form's source code in order to add any needed code, but as you already stated above, it's required to update the source code each time you update your form on the JotForm builder. 

If you only need to handle the data entered on the fields, you could do it capturing the submitted information, then process it on your end and send it to your software. 

This guide will help you getting the submitted data: https://www.jotform.com/help/213-Send-Submission-Data-via-Post-Method-and-Thank-You-Settings 

You may also want to take a look to the WebHooks integration that will also allow you to capture the submitted information: https://www.jotform.com/help/245-How-to-Setup-a-Webhook-with-JotForm 

I hope this helps.
