Keep users engaged and organized
Millions of people use Google Calendar to track their events. The Calendar API lets you integrate your app with Google Calendar, creating new ways for you to engage your users.
Integrate with mobile and web apps
You can use the Google Calendar API to find and view public calendar events. If you're authorized, you can also access and modify private calendars and events on those calendars.
Use the Google Calendar API to achieve deeper integration with Google Calendar. Mobile apps, Web apps, and other systems can create, display, or sync with Calendar data.

Creating events in Google Calendar
Have you ever booked a dining reservation, plane ticket, hotel room, concert ticket, or seats to the game from your favorite app, only to have to exit that booking app to enter the details into your calendar? Why can’t today’s apps do that for you automatically? It doesn't have to be like that. Learn how to create events using the Google Calendar API, giving your users a better experience. (7:14)
Modifying events with the Google Calendar API
Creating events is great, but even more powerful is the ability to modify existing events. If you have a booking app, now you can automatically update a user's calendar automatically so they don't have to do it manually, or worse, have 2 Calendar entries where one's wrong. In this video, learn how to do modify events with the Calendar API, and as a bonus, also learn how to make events repeat (recurring). (6:33)

A more flexible approach to sending event change notifications is
now available through the
sendUpdatesparameter. The new parameter lets you set event change notifications to do one of the following:
- notify all the event guests.
- notify only the guests who are not using Google Calendar.
- completely suppress the notifications, for example, during a migration.
