General > Calendars > Appointments > Creating New Appointments
Lastly, you can use the new appointment button to create a new appointment. Doing so will bring up the appointment editor, allowing you to select a primary contact, calendar, set an appointment title and description, set the assigned user, and set a time slot.
This option is useful for when you’ve agreed to a time slot over a call or in person and don’t want to send a booking link to your contact, but instead just want to send a calendar invite.
Third-Party Calendar Integrations
Keep in mind that if your third-party calendar (such as Google Calendar) is integrated, you can also send an invite to the user through there and your selected time will still appear in the system, however it will appear as a blocked slot rather than as an appointment.
