Getting user additional attributes

Петр Петренко

I need to get user additional attributes from jira api. I have found user() function but I don't know what I need to use in 'expand' parameter. I think that it is something dictionary but what shoud be key or value. Now I'm getting only three key-value: displayName, key and name.
Can you help me?

Jira api doesn't have that functional. You can get only groups and roles for user with it.
I've got need information from database.
