सी # का उपयोग कर व्हाट्सएप एपीआई कैसे भेजें

परिचय

इस लेख में, हम c# का उपयोग करके व्हाट्सएप एपीआई के माध्यम से संदेश भेजने के लिए सरल उदाहरण बनाएंगे।

प्रारंभ में, आपको यह सुनिश्चित करना चाहिए कि रेस्टशर्प पुस्तकालय अंतिम Ver: 108.0.1 तैयार है और क्योंकि हम इस लेख में इस पुस्तकालय का उपयोग Ultramsg गेटवे पर संदेश भेजने के लिए करेंगे।

सी # का उपयोग कर व्हाट्सएप एपीआई के लिए त्वरित उदाहरण

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);
        }
    }
}

जब पिछला कोड निष्पादित होता है, और यदि संदेश सफलतापूर्वक भेजा जाता है, तो प्रतिक्रिया इस प्रकार होगी:

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

रेस्टशर्प का उपयोग करके छवि को बेस 64 के रूप में भेजने का उदाहरण

स्थानीय पीसी या सर्वर से चित्र और दस्तावेज़ भेजने के लिए, आप फ़ाइलों को बेस 64 प्रारूप में परिवर्तित कर सकते हैं और उन्हें निम्न कोड के माध्यम से आसानी से भेज सकते हैं:
