Hi 
I'm looking for an api... I want to get all users list (about 800 users) with their phone numbers-(not all of their profile fields).
I've visited REST APIs of LUP, but I don't know how to select more than one field.
I tried this for userlist:
/rest/api/group/groupname/member
and this one for phone numbers:
/rest/cup/1.0/fields/{fieldKey}
