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

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class newJavaFile {

    /**

     */
    public static void main(String args[]) throws IOException {
