Get multiple records Employment API

Justin Stein

I am trying to get the campuses on which all of my teachers and staff work. The user extended list gives me most of the info I need, except for this component. I found the data in the Employment endpoint, but I really don't want to use 200 calls every time I run my program. Is there any way to get this data with fewer calls, or a way to add this data into the User extended list?
