This article represents code samples and changes that need to be done in original Linkedin-J framework (open-source) to get company updates of different types such as following:

• Job Posting
• Status Updates
• New Product

Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.

Code Samples & Steps to Get Company Updates

Following files need to be changed along with mentioned changes:

• LinkedinApiUrls.properties: Following code needs to be added under APIs mentioned under companies:

  com.google.code.linkedinapi.client.getCompanyStatusUpdates=http://api.linkedin.com/v1/companies/{id}/updates{queryParameters}
  

• LinkedInApiUrls.java: Following code needs to be added:

  public static final String GET_COMPANY_STATUS_UPDATES = linkedInApiUrls.getProperty("com.google.code.linkedinapi.client.getCompanyStatusUpdates");
  

• CompaniesApiClient.java: Following APIs need to be added:

      
  /**
   * Gets the company by id.
   * 
   * @param id the id
   * 
   * @return the company by id
   */public Updates getCompanyStatusUpdates(String id);
     
      
  /**
   * Get comanpy updates by companyid and event type 
   * @param id
   * @param eventType
   * @return
   */public Updates getCompanyStatusUpdates(String id, String eventType );
  
  /**
   * Get company updates by companyid, event type, start index, count
   * @param id
   * @param eventType
   * @param start
   * @param count
   * @return
   */public Updates getCompanyStatusUpdates(String id, String eventType, int start, int count);
  

• BaseLinkedInApiClient.java: Following implementations need to be added:

      
   @Override
   public Updates getCompanyStatusUpdates(String id) {
          assertNotNullOrEmpty("id", id);
  
          LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
          String                apiUrl  = builder.withEmptyField(ParameterNames.FIELD_SELECTORS).withField(ParameterNames.ID,
                   id).buildUrl();
  
          return readResponse(Updates.class, callApiMethod(apiUrl));
   }
   
          @Override
           public Updates getCompanyStatusUpdates(String id, String eventType) {
                  assertNotNullOrEmpty("id", id);
                  assertNotNullOrEmpty("eventtype", eventtype);
                  LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
                  String apiUrl = builder.withEmptyField(ParameterNames.FIELD_SELECTORS)
                                         .withField(ParameterNames.ID, id)
                                         .withParameter(ParameterNames.EVENT_TYPE, eventType).buildUrl();
  
                  return readResponse(Updates.class, callApiMethod(apiUrl));
           }
   
          @Override
          public Updates getCompanyStatusUpdates(String id, String eventType,
                         int start, int count) {
                  assertNotNullOrEmpty("id", id);
  
                  LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
                  String apiUrl = builder.withEmptyField(ParameterNames.FIELD_SELECTORS)
                                  .withField(ParameterNames.ID, id)
                                  .withParameter(ParameterNames.EVENT_TYPE, eventType)
                                  .withParameter(ParameterNames.START, String.valueOf(start))
                                  .withParameter(ParameterNames.COUNT, String.valueOf(count))
                                   .buildUrl();
  
                  return readResponse(Updates.class, callApiMethod(apiUrl));
          }
  

Once above files have been modified, you are all set to access the company status updates using following code:

public static void main(String[] args) {

        String consumerKeyValue = "your-consumer-key";
        String consumerSecretValue = "your-consumer-secret";

        String accessTokenValue = "use-your-access-token-value";
        String tokenSecretValue = "use-your-token-secret-value";

        final LinkedInApiClientFactory factory = LinkedInApiClientFactory.newInstance(consumerKeyValue, consumerSecretValue);
        final LinkedInApiClient client = factory.createLinkedInApiClient(accessTokenValue, tokenSecretValue);
 
        Updates updates = client.getCompanyStatusUpdates( "1441", "status-update", 10, 10 );
        List ulist  = updates.getUpdateList();
        if( ulist != null ) {
                Iterator uiter = ulist.iterator();
                while( uiter.hasNext() ) {
                        Update update = uiter.next();
                        CompanyStatusUpdate csu = update.getUpdateContent().getCompanyStatusUpdate();
                        if( csu != null ) {
                            System.out.println( "Status Updates: " + cssu.getShare().getComment() );
                        }
                }
        }
}
