Create Issue with Form data using API

[Marc Lloyd Menguito]

Hi, I have a JIRA Project where the setup is when the user creates an issue, they input data into the form from the portal. This form is then attached to the ticket, so I guess technically it's not in the same "screen"? 

Now when I use the get issue API for this ticket, it returns the customfields and their value, but when I try to create an issue using the POST API, it returns the error:

Field 'customfield_10222' cannot be set. It is not on the appropriate screen, or unknown.

I have tried looking for documentations related to forms API and the post issue API.

I have tried looking at forms API as well but it doesn't look like there's an API to submit a new form on a new issue.

Update: It looks like the servicedesk REST API has what I need. So i'll be looking into that.

So the answer to my question was POST /rest/servicedeskapi/request.

My only issue is the format of the "users" object in the form object.

according to the documentation the format is 

"qm:a713c8ea-1075-4e30-9d96-891a7d181739:5ad6d69abfa3980ce712caae"

I am assuming the first half is the cloud id since that matches the format...

and the second half is the user id.
