ShiftZen is used to schedule shifts for employees working at small to large restaurants. ShiftZen can be accessed online and through an app accessible on most devices. Using ShiftZen, users have the ability to view a weekly schedule and look up who is working when. Employees can update their availability, request time off and make requests to swap shifts with others. Using SOAP and XML, ShiftZen API can be called over HTTP to allow staff details and availability times to be pulled into other applications, such as different systems that handle restaurant schedules. Also using the API, company and employee information can be programmatically created and retrieved for the purpose of scheduling and managing work hours.
