The next step to a client is to pick a date and time of his service. We've used a Bootstrap date-picker in API-usage example, you can also use this or any other calendar. To set your calendar first date use getFirstWorkingDay method. It can take employee id as a parameter and returns the next date when the selected employee (or any employee in the company by default) is avaiable for booking. To show time slots inside a selected date you need getWorkCalendar and getStartTimeMatrix methods. The first method give you an information about working day start and end time, and about day-offs. And the second one returns the list of time-slots which can be booked for a certain date.
