C# ile WhatsApp API Nasıl Gönderilir?

Giriş

Bu yazımızda c# kullanarak WhatsApp API üzerinden mesaj göndermek için basit örnekler oluşturacağız.

Öncelikle RestSharp kütüphanesinin son Ver:108.0.1’in hazır olduğundan emin olmalısınız ve bu yazımızda bu kütüphaneyi Ultramsg Gateway’e mesaj göndermek için kullanacağız.

C# kullanarak WhatsApp API için hızlı Örnek

using System;
using RestSharp;
using System.Threading.Tasks;

namespace test
{
    class Program
    {
        static async Task Main(string[] args)
        {
           
            string instanceId = "instance950"; // your instanceId
            string token = "yourtoken";         //instance Token
            string mobile = "14155552671";      
            string message = "WhatsApp API on UltraMsg.com works good";
            var url = "https://api.ultramsg.com/" + instanceId  +  "/messages/chat";
            var client = new RestClient(url);
            var request = new RestRequest(url, Method.Post);
            request.AddHeader("content-type", "application/x-www-form-urlencoded");
            request.AddParameter("token", token);
            request.AddParameter("to", mobile);
            request.AddParameter("body", message);


            RestResponse response = await client.ExecuteAsync(request);
            var output = response.Content;
            Console.WriteLine(output);
        }
    }
}

Önceki kod çalıştırıldığında ve mesaj başarılı bir şekilde gönderildiğinde, yanıt şu şekilde olacaktır:

{"sent":"true","message":"ok","id":497}
