Calendar API には、主に Google Workspace のお客様に役立つコンセプトがいくつか用意されています。このようなお客様は、特定のイベントのために予約したいリソース(会議室、プロジェクターなど)をお持ちの場合があります。また、ドメイン内のすべてのユーザーのカレンダーにアクセスする必要がある内部アプリ(会社のイベントをカレンダーに追加するアプリなど)を構築することも一般的です。

These customers often have\nresources---rooms, projectors, and so forth---that they may wish to\nbook for specific events. Furthermore, it's common to build internal apps that\nneed access to all user calendars in a domain, for example to add corporate\nevents to them.\n\nDomain resources \\& rooms\n-------------------------\n\nYou can book resources and rooms by adding them to events as attendees, using\ntheir email address. When they receive the invitation, they automatically\naccept or decline the event based on the availability and access right of the\ninviting user.\n| **Note:** The Calendar API does not offer a way to create resource calendars. To do this, you need to use the Directory API's [Calendar Resource](/workspace/admin/directory/reference/rest/v1/resources.calendars) object. The calendarId corresponds to the resourceEmail field of the Calendar Resource representation.\n\nAccessing domain calendars as an app\n------------------------------------\n\nAn app can access domain-owned calendars without requiring\nuser credentials if it authenticates using a [service\naccount](/identity/protocols/OAuth2ServiceAccount). The service account must\nhave the necessary access using [domain-wide authority\ndelegation](/identity/protocols/OAuth2ServiceAccount#delegatingauthority). In\norder to impersonate a user account, specify the email address of the user\naccount with the `setServiceAccountUser` method of the `GoogleCredential`\nfactory."]]
