Change question values via API

Hi,

I recently started using Dual ListBox widget, and I want to change its Values (Option 1, Option 2, etc.) via API call.

I am calling POST http://eu-api.jotform.com/form/92816321177357/question/39
headers: APIKEY=XXX
request: raw - application/json

but I am not so sure about the content...
Current value:"listboxItems": "Option 1\nOption 2\nOption X"
But when I tried to put this into content:
{
"content": {
"listboxItems": "Test 1\nTest 2\nTest X"
}
}
nothing actually happened.

Same for the Dymanic dropdowns widget.
I just can't seem to get the right name of the fields which I need to edit I guess?

The purpose is to keep my Form dynamic, if I edit list of my material in my database, I need it to pass the change to the form and add the new value.

Could you please provide me the correct content to change its values?

Many thanks,

David

I am not sure if that is possible for widgets. But please check here: http://api.jotform.com/docs/#post-form-id-question-id

Hi, I did check your APIs, but I can not find anything about what I want to integrate, nor anything about widget fields..

Guess I will try to contact your API team.
