Google Calendar Integration

The event calendar comes with third party calendar integration support through the integration plugin. This needs to be added to the download package or installed separately from a dedicated NPM package.

It includes everything you need to authenticate your users, get their Google calendars and provides functions for CRUD operations. It takes care of loading the events and converts them to the required format so that they can be displayed on the Mobiscroll calendar separately or mixed with other calendars and events.

Customizing the interaction, event workflows, whether the events are read-only is up to you. In this live demo, newly created events will land in the primary calendar of the authenticated user.

This example uses the integration plugin to connect to and load events from Google Calendar and it is not available in the trial. Give the live demo a try and see how it can be configured.

Connect the Scheduler to Google Calendar — authenticate users, load calendars, and sync create, edit, or delete events in real time via the integration plugin.
