The Workers APIs support the management of workers in an organization. A worker is a person who performs duties and responsibilities for an organization. In that capacity, a worker fills one or more positions via a work assignment. For a given work assignment, a worker is related to the organization as an employee or contractor. The Workers APIs can be used to obtain a list of all workers in an organization and to get information about work assignments.

Time Entry v1
Time Entry is the act of logging time by a worker. The Time Entry APIs support 3 types of entries: Clock, Time Entry (hours) or Time pairs. These APIs support the viewing of entries for a time period as specified by the System of Record (SOR) and may allow the creation and deletion of time entries based on rules determined by the SOR. If authorized, the APIs support the resolution of exceptions in a timesheet and the review of timesheets (i.e. approval process).
