Enumerate Principals

GET /principals

Lists principals owned by the authenticated caller by default. Supplying an owner selects that owner's principals, subject to the caller's principal-read permissions. Supplying an ID selects a single principal, subject to the same permission check. The default page size is 10 and the maximum page size is 100.

Requires a signed user/session or the existing authenticated client flow. The anonymous DCR delegated device profile cannot invoke this operation.
