How to send pre-populated hidden fields on webhook call

Hi,

I've got 2 nested jotforms. The second form pre-populates fields from the first, and it hides all the fields that are pre-populated (so the user doesn't have to confirm).

Hiding the fields on the 2nd form based on the fields pre-populated from the first works fine, however when the contents of the 2nd form are sent on a webhook, they don't contain any of the fields pre-populated. How can I get these?

Screenshot shows that the contents of those fields on the 2nd form are NOT being sent onto the webhook upon submission, even though I'm pre-populating them from the first onto the 2nd

You can easily test your webhooks integration with requestbin 

You can make a webhook request e.g. form field names & its sample data, you can use RequestBin. Simply create a requestbin URL and set it as your form Webhook (as seen in the screenshot above). Make a sample submission to your form and requestbin will automatically collect the data and print it in a human-friendly way.

You can find more details about it in the following Guide : https://www.jotform.com/help/245-How-to-Setup-a-Webhook-with-JotForm
