In an embodiment, a method of facilitating presentation and user selection of at least one timeslot, such as for an appointment, is presented. In this method, a request for available timeslots within a time period is received from a user device. In response, timeslot data identifying the available timeslots is retrieved from a scheduling system. An identifier key for each of the available timeslots, as well as graphical display data indicating the available time slots, are generated based on the timeslot data. The keys and the graphical display data are transmitted to the user device. A selection of at least one of the identifier keys is received from the user device. In response to receiving the selection, the at least one available timeslot corresponding to the selection is determined and forwarded to the scheduling system to reserve the at least one corresponding available timeslot.
