B4J Question rest api

Can you help me to connect to rest api of an organisation with b4j ?
I have user name and api key.The sample for connection is in java code.


sample code:

import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class JavaSample
{
public static void main(String[] args)
{
HttpClient httpclient = HttpClients.createDefault();

try
{
URIBuilder builder = new URIBuilder("https://mydata-dev.azure-api.net/RequestDocs");

builder.setParameter("mark", "{mark}");

URI uri = builder.build();
HttpGet request = new HttpGet(uri);
request.setHeader("aade-user-id", "{aade-user-id}");
request.setHeader("Ocp-Apim-Subscription-Key", "{subscription key}");


// Request body
StringEntity reqEntity = new StringEntity("{body}");
request.setEntity(reqEntity);

HttpResponse response = httpclient.execute(request);
HttpEntity entity = response.getEntity();

if (entity != null)
{
System.out.println(EntityUtils.toString(entity));
}
}
catch (Exception e)
{
System.out.println(e.getMessage());
}
}
}
