## Linkedin Component

*Available as of Camel version 2.14*

The LinkedIn component provides access to all of LinkedIn REST APIs
documented
at https://developer.linkedin.com/rest[https://developer.linkedin.com/rest]. 

LinkedIn uses OAuth2.0 for all client application authentication. In
order to use camel-linkedin with your account, you'll need to create a
new application for LinkedIn at
https://www.linkedin.com/secure/developer[https://www.linkedin.com/secure/developer].
The LinkedIn application's client id and secret will allow access to
LinkedIn REST APIs which require a current user. A user access token is
generated and managed by component for an end user. Alternatively the
Camel application can register an implementation
of org.apache.camel.component.linkedin.api.OAuthSecureStorage to provide
an org.apache.camel.component.linkedin.apiOAuthToken OAuth token.

Maven users will need to add the following dependency to their pom.xml
for this component:

[source,java]
-----------------------------------------------
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-linkedin</artifactId>
        <version>${camel-version}</version>
    </dependency>
-----------------------------------------------

### URI format

[source,java]
-------------------------------------------------
    linkedin://endpoint-prefix/endpoint?[options]
-------------------------------------------------

Endpoint prefix can be one of:

* comments
* companies
* groups
* jobs
* people
* posts
* search

### LinkedInComponent




// component options: START
The Linkedin component supports 2 options which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|=======================================================================
| Name | Description | Default | Type
| **configuration** (common) | To use the shared configuration |  | LinkedInConfiguration
| **resolveProperty Placeholders** (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean
|=======================================================================
// component options: END





// endpoint options: START
The Linkedin endpoint is configured using URI syntax:

    linkedin:apiName/methodName

with the following path and query parameters:

#### Path Parameters (2 parameters):

[width="100%",cols="2,5,^1,2",options="header"]
|=======================================================================
| Name | Description | Default | Type
| **apiName** | *Required* What kind of operation to perform |  | LinkedInApiName
| **methodName** | *Required* What sub operation to use for the selected operation |  | String
|=======================================================================

#### Query Parameters (14 parameters):

[width="100%",cols="2,5,^1,2",options="header"]
|=======================================================================
| Name | Description | Default | Type
| **clientId** (common) | LinkedIn application client ID |  | String
| **clientSecret** (common) | LinkedIn application client secret |  | String
| **httpParams** (common) | Custom HTTP params for example proxy host and port use constants from AllClientPNames |  | Map
| **inBody** (common) | Sets the name of a parameter to be passed in the exchange In Body |  | String
| **lazyAuth** (common) | Flag to enable/disable lazy OAuth default is true. when enabled OAuth token retrieval or generation is not done until the first REST call | true | boolean
| **redirectUri** (common) | Application redirect URI although the component never redirects to this page to avoid having to have a functioning redirect server. So for testing one could use https://localhost |  | String
| **scopes** (common) | List of LinkedIn scopes as specified at https://developer.linkedin.com/documents/authenticationgranting |  | OAuthScope[]
| **secureStorage** (common) | Callback interface for providing an OAuth token or to store the token generated by the component. The callback should return null on the first call and then save the created token in the saveToken() callback. If the callback returns null the first time a userPassword MUST be provided |  | OAuthSecureStorage
| **userName** (common) | LinkedIn user account name MUST be provided |  | String
| **userPassword** (common) | LinkedIn account password |  | String
| **bridgeErrorHandler** (consumer) | Allows for bridging the consumer to the Camel routing Error Handler which mean any exceptions occurred while the consumer is trying to pickup incoming messages or the likes will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions that will be logged at WARN or ERROR level and ignored. | false | boolean
| **exceptionHandler** (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions that will be logged at WARN or ERROR level and ignored. |  | ExceptionHandler
| **exchangePattern** (consumer) | Sets the exchange pattern when the consumer creates an exchange. |  | ExchangePattern
| **synchronous** (advanced) | Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported). | false | boolean
|=======================================================================
// endpoint options: END


### Producer Endpoints:

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 *CamelLinkedIn.<option>*. Note that the *inBody* option
overrides message header, i.e. the endpoint option *inBody=option* would
override a *CamelLinkedIn.option* header.

For more information on the endpoints and options see LinkedIn REST API
documentation
at https://developer.linkedin.com/rest[https://developer.linkedin.com/rest].

### Consumer Endpoints

Any of the producer endpoints can be used as a consumer endpoint.
Consumer endpoints can
use http://camel.apache.org/polling-consumer.html#PollingConsumer-ScheduledPollConsumerOptions[Scheduled
Poll Consumer Options] with a *consumer.* prefix to schedule endpoint
invocation. By default Consumer endpoints that return an array or
collection will generate one exchange per element, and their routes will
be executed once for each exchange. To change this behavior use the
property *consumer.splitResults=true* to return a single exchange for
the entire list or array. 

### Message Headers

Any URI option can be provided in a message header for producer
endpoints with a *CamelLinkedIn.* prefix.

### Message body

All result message bodies utilize objects provided by the Camel LinkedIn
API SDK, which is built using Apache CXF JAX-RS. Producer endpoints can
specify the option name for incoming message body in the *inBody*
endpoint parameter.

### Use cases

The following route gets user's profile:

[source,java]
----------------------------------------
    from("direct:foo")
        .to("linkedin://people/person");
----------------------------------------

The following route polls user's connections every 30 seconds:

[source,java]
-------------------------------------------------------------------------------------
    from("linkedin://people/connections?consumer.timeUnit=SECONDS&consumer.delay=30")
        .to("bean:foo");
-------------------------------------------------------------------------------------

The following route uses a producer with dynamic header options. The
*personId* header has the LinkedIn person ID, so its assigned to the
*CamelLinkedIn.person_id* header as follows:

[source,java]
-----------------------------------------------------------------
    from("direct:foo")
        .setHeader("CamelLinkedIn.person_id", header("personId"))
        .to("linkedin://people/connectionsById")
        .to("bean://bar");
-----------------------------------------------------------------
