Google Calendar enables you to create external booking pages with shareable appointment scheduling.   Do you have any difficulties or confusion when scheduling appointments with external companies? Spending less time managing your appointments is what you want? If so, Google already launched the new appointment scheduling feature suited for external use cases. There is no need to use a third-party app to book appointments on your Google Calendar.    Previously, Google Calendar provided an appointment slot feature, but that limits internal company usage. However, with the feature update of appointment scheduling, it allows you to share your available time slots on the booking page which can be used by external users, clients, or partners for appointment booking.     Source:
