How to export custom form data in Jira Service Management without using custom fields?

[David Martínez López]

Hi everyone,

I'm trying to export the data from custom forms in Jira Service Management, but I’ve encountered a limitation: the fields inside the form are not linked to custom fields in Jira; they only exist within the form itself.

I have tried retrieving data through the Jira API (/rest/api/3/search), but it only returns the custom fields associated with issues, without including the form data filled in each ticket.

My question is:

🔹 Is there a way to access this data?
🔹 Or is there a specific API for forms in Jira Service Management?
🔹 Has anyone successfully extracted this data in a structured format (e.g., CSV or JSON)?

I’d really appreciate any guidance or experience you can share. Thanks!
