Google Calendar's appointment scheduling feature allows users to create a professional booking page where individuals with an email address can book appointments, view booked appointments alongside regular schedules, and customize availability, receive email notifications, and more. The feature is currently available on work and student Google accounts but not Google Workspace Business Starter accounts. Users can share the link or embed it on their website to access the booking page. Additionally, Google Calendar has integrated its scheduling feature with Gmail, allowing users to share availability and have recipients book a meeting directly from their inboxes. The feature can be automated using Zapier to connect with other apps and automate tasks such as sharing notifications and creating meeting agendas.
