Cara Menghantar API WhatsApp menggunakan c#

pengenalan

Dalam artikel ini, kami akan mencipta contoh mudah untuk menghantar mesej melalui API WhatsApp menggunakan c#.

Pada mulanya, anda mesti memastikan bahawa perpustakaan RestSharp terakhir Ver: 108.0.1 sudah sedia dan kerana kami akan menggunakan perpustakaan ini dalam artikel ini untuk menghantar mesej ke Gerbang Ultramsg.

Contoh pantas untuk API WhatsApp menggunakan C#

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);
        }
    }
}

Apabila kod sebelumnya dilaksanakan, dan jika mesej berjaya dihantar, respons akan menjadi seperti ini:

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