The Google Calendar component provides access to Google Calendar via the Google Calendar Web APIs.
Google Calendar uses the 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 create an account and generate OAuth credentials. Credentials comprise of a clientId, clientSecret, and a refreshToken. A handy resource for generating a long-lived refreshToken is the OAuth playground.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-google-calendar</artifactId>
<version>2.15-SNAPSHOT</version>
</dependency>The GoogleCalendar Component uses the following URI format:
google-calendar://endpoint-prefix/endpoint?[options]
Endpoint prefix can be one of:
acl
calendars
channels
colors
events
freebusy
list
settings
The GoogleCalendar Component can be configured with the options below. These options
can be provided using the component's bean property configuration of type
org.apache.camel.component.google.calendar.GoogleCalendarConfiguration.
| Option | Type | |
|---|---|---|
| accessToken | String | OAuth 2 access token. This typically expires after an hour so refreshToken is recommended for long term usage. |
| applicationName | String | Google calendar application name. Example would be "camel-google-calendar/1.0" |
| clientId | String | Client ID of the calendar application |
| clientSecret | String | Client secret of the calendar application |
| refreshToken | String |
OAuth 2 refresh token. Using this, the Google Calendar component can obtain a new accessToken whenever the current one expires - a necessity if the application is long-lived. |
| scopes | List<String> | Specifies the level of permissions you want a calendar application to have to a user account. See https://developers.google.com/google-apps/calendar/auth for more info. |
Producer endpoints can use endpoint prefixes followed by endpoint names and associated options described next. A shorthand alias can be used for some endpoints. The endpoint URI MUST contain a prefix.
Endpoint options that are not mandatory are denoted by []. When there are no mandatory
options for an endpoint, one of the set of [] options MUST be provided. Producer
endpoints can also use a special option inBody that in turn should contain the name of the endpoint
option whose value will be contained in the Camel Exchange In message.
Any of the endpoint options can be provided in either the endpoint URI, or dynamically
in a message header. The message header name must be of the format
CamelGoogleCalendar.<option>. Note that the inBody
option overrides message header, i.e. the endpoint option inBody=option
would override a CamelGoogleCalendar.option header.
The following endpoints can be invoked with the prefix acl as

Any of the producer endpoints can be used as a consumer endpoint. Consumer endpoints
can use Scheduled Poll Consumer Options with a consumer. prefix to
schedule endpoint invocation. Consumer endpoints that return an array or collection will
generate one exchange per element, and their routes will be executed once for each
exchange.
Any URI option can be provided in a message header for producer endpoints with a
CamelGoogleCalendar. prefix.
All result message bodies utilize objects provided by the underlying APIs used by the
GoogleCalendarComponent. Producer endpoints can specify the option name for incoming
message body in the inBody endpoint URI parameter. For endpoints that
return an array or collection, a consumer endpoint will map every element to distinct
messages.
