Google Calendar API Push notifications: don’t call us, we’ll call you

Google has introduced Push notifications for the Google Calendar API, eliminating the need for applications to periodically poll for event changes to stay synchronized. This new feature allows apps to significantly reduce data usage and power consumption, especially on mobile devices, by enabling them to subscribe to a calendar and receive notifications whenever changes occur. Developers can easily implement this functionality using Google API client libraries, and upon receiving a notification, the app performs an API call to update its data. This advancement streamlines the process of keeping applications in sync with the Google Calendar server, ensuring timely updates and improved efficiency.
