The Google Calendar Stream component provides access
to https://calendar.google.com[Calendar] via
the https://developers.google.com/calendar/overview[Google Calendar
Web APIs]. This component provides the streaming feature for Calendar events.

Google Calendar uses
the https://developers.google.com/accounts/docs/OAuth2[OAuth 2.0
protocol] for authenticating a Google account and authorizing access to
user data. Before you can use this component, you will need
to https://developers.google.com/calendar/auth[create an
account and generate OAuth credentials]. Credentials consist of a
`clientId`, `clientSecret`, and a `refreshToken`. A handy resource for
generating a long-lived `refreshToken` is
the https://developers.google.com/oauthplayground[OAuth playground].

In the case of a https://developers.google.com/identity/protocols/oauth2#serviceaccount[service account],
credentials consist of a JSON-file (serviceAccountKey). You can also use
https://developers.google.com/identity/protocols/oauth2/service-account#delegatingauthority[delegation domain-wide authority]
(delegate) and one, several, or all possible
https://developers.google.com/calendar/api/guides/auth[Calendar API Auth Scopes].

for this component:
