Not able to access Request Token to use REST API in Magento 2

[paul-sidd]

Followed these steps:

1. created new integration in magento 2 through admin console.
2. Activated the new integration created in first step.
3. copied the consumer key and consumer secret.
4. using scribe framework, tried to access the request token key , but getting error

Exception in thread "main" org.scribe.exceptions.OAuthException: Response body is incorrect. Can't extract token and secret from this: 'oauth_problem=Cannot+create+request+token+because+consumer+token+is+not+a+verifier+token'

Can someone help to identify the root cause and the possible rectification?

source code:

package com.cartnship.UsingScribe;

import org.scribe.builder.api.DefaultApi10a;
import org.scribe.model.Token;

API class:

public class MagentoThreeLeggedOAuth extends DefaultApi10a{
public static final String BASE_URL ="http:///magento2/";
@OverRide
public String getAccessTokenEndpoint() {
// TODO Auto-generated method stub
return BASE_URL+"oauth/token/access";
}

@Override
public String getAuthorizationUrl(Token requestToken) {
    // TODO Auto-generated method stub
    return BASE_URL + "admin/oauth_authorize?oauth_token="+ requestToken.getToken();
}

@Override
public String getRequestTokenEndpoint() {
    // TODO Auto-generated method stub
    return BASE_URL+"oauth/token/request";
}

}

App class(Main class)

package com.cartnship.UsingScribe;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.concurrent.TimeUnit;

import org.scribe.builder.ServiceBuilder;
import org.scribe.model.SignatureType;
import org.scribe.model.Token;
import org.scribe.oauth.OAuth10aServiceImpl;
import org.scribe.oauth.OAuthService;

public class App
{
public static void main( String[] args )
{
try {
OutputStream stream=new FileOutputStream(new File("D:/output.txt"));

        String YOUR_API_KEY="ddv876ki1c8ll417r3qc0wppehefdbwx";
        String YOUR_API_SECRET="hpsfvmxdk26442a3vdrp1gkm8yv68d36";

        OAuth10aServiceImpl service =(OAuth10aServiceImpl) new ServiceBuilder().provider(MagentoThreeLeggedOAuth.class)
            .apiKey(YOUR_API_KEY)
            .apiSecret(YOUR_API_SECRET)
            .debugStream(stream)
            .build();

    Token requestToken=service.getRequestToken(60, TimeUnit.SECONDS);
    String authorizationUrl=service.getAuthorizationUrl(requestToken);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
