Google Calendar Event ID global or not? -
is event id unique globally on whole google or in calendar?
it looks this: 2tdcb4eepthqj01qltpi4txfcs
id: opaque identifier of event. when creating new single or recurring events, can specify ids. provided ids must follow these rules: characters allowed in id used in base32hex encoding, i.e. lowercase letters a-v , digits 0-9, see section 3.1.2 in rfc2938 length of id must between 5 , 1024 characters id must unique per calendar
due globally distributed nature of system, cannot guarantee id collisions detected @ event creation time. minimize risk of collisions recommend using established uuid algorithm such 1 described in rfc4122. if not specify id, automatically generated server.
note icaluid , id not identical , 1 of them should supplied @ event creation time. 1 difference in semantics in recurring events, occurrences of 1 event have different ids while share same icaluids.
about event:
visibility of event. optional. possible values are: "default" - uses default visibility events on calendar. default value. "public" - event public , event details visible readers of calendar. "private" - event private , event attendees may view event details. "confidential" - event private. value provided compatibility reasons.
