Введение
В этом руководстве мы создадим простые примеры для отправки сообщений через API WhatsApp с использованием Java.
Изначально необходимо убедиться, что okhttp3 библиотека готова Потому что в этой статье мы будем использовать эту библиотеку для отправки сообщений на шлюз Ultramsg.
Первое сообщение WhatsApp API с использованием 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;
/**

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());
}
}
При выполнении предыдущего кода и успешной отправке сообщения ответ будет таким:
{"sent":"true","message":"ok","id":43007}
