Google Calendar Sync

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, the different calendars are handled as resources and have their own timeline rows. You can manipulate events in the desired calendars, while read-only calendars are greyed out.

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.
