Pesan API WhatsApp Pertama Menggunakan Java

package com.mycompany.mavenproject1;
import java.io.IOException;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

/**

 * @author Ultramsg team
 */
public class newJavaFile {

    /**
     * @param args the command line arguments
     */
    public static void main(String args[]) throws IOException {
  //////////////////////////////////////
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(mediaType, "token=JATafg4422g0K54&to=14155552671&body=WhatsApp API on UltraMsg.com works good&priority=10&referenceId=");
Request request = new Request.Builder()
  .url("https://api.ultramsg.com/instance19/messages/chat")
  .post(body)
  .addHeader("content-type", "application/x-www-form-urlencoded")
  .build();
Response response = client.newCall(request).execute();
//////////////////////////////////////
     System.out.println("===================");
     System.out.println(response.body().string());
    }
}
