get https://api.bamboohr.com/api/gateway.php//v1/employees/changed
This API allows for efficient syncing of employee data. When you use this API you will provide a timestamp and the results will be limited to just the employees that have changed since the time you provided. This API operates on an employee-last-changed-timestamp, which means that a change in ANY individual field in the employee record, as well as any change to the employment status, job info, or compensation tables, will cause that employee to be returned via this API.
