pengantar
Pada artikel ini, kami akan membuat contoh sederhana untuk mengirim pesan melalui WhatsApp API menggunakan c#.
Awalnya, Anda harus memastikan bahwa pustaka RestSharp Ver terakhir: 108.0.1 sudah siap dan karena kami akan menggunakan pustaka ini dalam artikel ini untuk mengirim pesan ke Ultramsg Gateway.
Contoh cepat untuk WhatsApp API 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);
}
}
}Ketika kode sebelumnya dijalankan, dan jika pesan berhasil dikirim, responsnya akan seperti ini:
{"sent":"true","message":"ok","id":497}Kirim Gambar

Contoh untuk mengirim gambar sebagai Base64 menggunakan RestSharp
Untuk mengirim gambar dan dokumen dari pc atau server lokal, Anda dapat mengonversi file ke format base64 dan mengirimkannya dengan mudah melalui kode berikut:
using System;
using RestSharp;
using System.Threading.Tasks;
using System.IO;
namespace test
{
class Program
{
static async Task Main(string[] args)
{
string instanceId = "instance950"; // your instanceId
string token = "yourtoken"; //instance Token
string mobile = "14155552671";
byte[] AsBytes = File.ReadAllBytes("test.jpeg");
String AsBase64String = Convert.ToBase64String(AsBytes);
var url = "https://api.ultramsg.com/" + instanceId + "/messages/image";
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("image", AsBase64String);
RestResponse response = await client.ExecuteAsync(request);
var output = response.Content;
Console.WriteLine(output);
}
}
}
Contoh untuk mengirim dokumen sebagai Base64 menggunakan RestSharp
using System;
using RestSharp;
using System.Threading.Tasks;
using System.IO;
namespace test
{
class Program
{
static async Task Main(string[] args)
{
string instanceId = "instance950"; // your instanceId
string token = "yourtoken"; //instance Token
string mobile = "14155552671";
byte[] AsBytes = File.ReadAllBytes("test.pdf");
String AsBase64String = Convert.ToBase64String(AsBytes);
var url = "https://api.ultramsg.com/" + instanceId + "/messages/document";
var client = new RestClient(url);
var request = new RestRequest(url, Method.Post);
request.AddHeader("content-type", "application/x-www-form-urlencoded");

request.AddParameter("filename", "WhatsApp-API.pdf");
request.AddParameter("document", AsBase64String);
RestResponse response = await client.ExecuteAsync(request);
var output = response.Content;
Console.WriteLine(output);
}
}
}API WhatsApp menggunakan C# dengan WebClient
itu Tidak disarankan untuk pekerjaan baru tetapi sangat mudah, jika Anda perlu melakukan permintaan http secara sinkron,WebClient masih bisa digunakan.
using System;
using System.Collections.Specialized;
using System.Net;
using System.Text;
public class Program
{
public static void Main()
{
using (var wb = new WebClient())
{
var data = new NameValueCollection();
data["token"] = "95041eyo9eqixrsi";
data["body"] = "WhatsApp API on UltraMsg.com works good";
data["to"] = "14155552671";
var response =
wb
.UploadValues("https://api.ultramsg.com/instance950/messages/chat",
"POST",
data);
string responseInString = Encoding.UTF8.GetString(response);
Console.WriteLine (responseInString);
}
///////////

}
Contoh untuk mengirim dokumen sebagai Base64 menggunakan c# & WebClient
using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.IO;
using System.Net;
using System.Text;
using System.Web;
public class Program
{
public static void Main()
{
using (var wb = new WebClient())
{
byte[] AsBytes = File.ReadAllBytes("1.pdf");
String AsBase64String = Convert.ToBase64String(AsBytes);
var data = new NameValueCollection();
data["token"] = "95041eyo9eqixrsi";
data["to"] = "14155552671";
data["document"] = AsBase64String;
data["filename"] = "a.pdf";
var response =
wb
.UploadValues("https://api.ultramsg.com/instance950/messages/document",
"POST",
data);
string responseInString = Encoding.UTF8.GetString(response);
Console.WriteLine (responseInString);
