Calendar identifier. To retrieve calendar IDs call the calendarList.list method. If you want to access the primary calendar of the currently logged in user, use the "primary" keyword.

Query parameters

colorRgbFormatboolean

Request body

accessRolestring

The effective access role that the authenticated user has on the calendar. Read-only. Possible values are:

"freeBusyReader" - Provides read access to free/busy information.
"reader" - Provides read access to the calendar. Private events will appear to users with reader access, but event details will be hidden.
"writerWithoutPrivateAccess" - Provides read and write access to the calendar. Private events will appear to users with writerWithoutPrivateAccess access, but event details will be hidden.
"writer" - Provides read and write access to the calendar. Private events will appear to users with writer access, and event details will be visible.
"owner" - Provides manager access to the calendar. This role has all of the permissions of the writer role with the additional ability to see and modify access levels of other users.
