Workday Bridge
This site serves two things to the Workday Bridge Thin program on your computer, and nothing else:
library.json: which report library is newest. The bridge asks before it applies one, and checks its signature./callback/: the sign-in hand-over. Workday sends your browser there after you sign in, and the page passes the one-time code straight to the bridge on your computer.
