How to get all system fields using JIRA API

[Khromov Maksim]

I need to get all system fields using JIRA API and filter them by type. i.e. all system user pickers.

How to do it ?

In the JIRA REST API doc, there are many available options for you:

• http://example.com:8080/jira/rest/api/2/issue/picker [GET]
• http://example.com:8080/jira/rest/api/2/screens/{screenId}/availableFields [GET]
