Can we have a list of system fields in Cloud Jira ?

[Manoj Dasari]

I need to list out all the custom fields and system fields in the cloud jira .we are doing some clean up activities so need a list of system fields to get better understanding.

Hello @Manoj Dasari 

You can get that information using the REST API

Where custom = false

Cloud = Pain

Another reason I am also keen on getting a list of system fields because there has been many instances where jira admins unknowingly created custom fields for which a proper system already existed.

A list of system fields is not going to help you clean anything up.

You can't remove or amend them, so there's nothing to clean.  Just go to the list of custom fields and housekeep all of them.

you could clean screens and field configurations anyway and it would be helpful to understand what field is a system field and what not here

[Nic Brough -Adaptavist-]

No, it would not.

If you want to clean screens and field configurations, you should be looking at them to see what could be removed.  Whether a field is system or not is an utter irrelevance (except for Summary, which you must not remove from a create screen in any system).  

Clean the filed configurations first though, you need to know whether the field config has set a field mandatory.  If you do not want a field to appear in the project any more, you need to make sure you flip it to optional before you remove it from a create screen (unless you intend to delete it from the custom fields completely)
