You can create highly customized Google Calendar events using Zapier's Create Detailed Event action by mapping responses from a trigger app, such as a Google Form, to specific fields like event name, time, date, location, and description. You can also add custom reminders, virtual meeting links, start and end times, repeat frequencies, attendees, visibility, default reminders, and more. Once set up, the Zap will automatically create events in your Google Calendar based on new data from the trigger app, allowing you to streamline your workflow and stay organized.
