Getting Connections of a person by id in LinkedIn

Question

I need to get the connections of a user whose id is yZTcaxINNv. I use linkedin-j and the code looks something like this

import com.google.code.linkedinapi.client.LinkedInApiClient;
import com.google.code.linkedinapi.client.LinkedInApiClientFactory;
import com.google.code.linkedinapi.schema.Connections;
import com.google.code.linkedinapi.schema.Person;


public class Linkedin_Data_Extract {



public static void main(String[] args) {
       final String consumerKeyValue = "My key";
        final String consumerSecretValue ="My Secret";
        final String accessTokenValue = "Access Token";
        final String tokenSecretValue = "Secret";
        final String id = "yZTcaxINNv";


    final LinkedInApiClientFactory factory = LinkedInApiClientFactory.newInstance(consumerKeyValue, consumerSecretValue);
    final LinkedInApiClient client = factory.createLinkedInApiClient(accessTokenValue, tokenSecretValue);


    Connections cc=client.getConnectionsById(id);

    for(Person p :cc.getPersonList()) {
        System.out.println(p.getLastName());
        System.out.println(p.getId());
        System.out.println("Industry      "+p.getIndustry());
        System.out.println("currentStatus "+p.getCurrentStatus());
        System.out.println("link          "+p.getPublicProfileUrl());
        System.out.println("position      "+p.getEducations());
        System.out.println();
    }
    }
}

But i get an error like this

Exception in thread "main" com.google.code.linkedinapi.client.LinkedInApiClientException: Access to connections denied
at com.google.code.linkedinapi.client.impl.BaseLinkedInApiClient.createLinkedInApiClientException(BaseLinkedInApiClient.java:3906)

Why am i getting permission issues

Answer 1

Third-party APIs that access other users information through OAuth need to be explicitly allowed permission by the user himself.

Normally, this happens through a popup window where the user is asked to allow/reject your app to operate on his data. I'm guessing this is where your issue comes from.

I don't know how linkedin-j does this, but in case you are up for alternatives, you could give Spring Social a try, which has a module addressed specifically for Linkedin. See the Quickstart sample in the page I gave you if you're curious
