How to Send WhatsApp Message Through Asp.Net

In this article I’m going to show you "How to Send WhatsApp Message by Using C# Coding", first design Web Application as shown in above image. Before writing code to send WhatsApp message first we need to Install WhatsApp API in our application, based on this WhatsApp API we can create object for WhatsApp. By using WhatsApp Object we can call WhatsApp Methods.

WhatsApp Methods: OnConnectSuccess, OnLoginSuccess , OnLoginFailed, OnConnectFailed

First Download WART tools from this Link WART Tools

After Download, you can run WART.exe file.

Enter your mobile number with area code and enter password which is associate with your WhatsApp account. Now, click on “Request Code” Button which will get you 4 digit confirmation code in your registration mobile number.

 Enter confirmation code and click on Confirmation code which will display password. Please Note down this generated password. This password is enter in password field at run time of project.

Now Design your Webpage like below.

Write code on “Send” button click event.

protected void BtnSEND_Click(object sender, EventArgs e)

{

   string number = "91**********"; // use number which is register from WART tool

   string to = txtTo.Text;

   string msg = txtMSG.Text;

   string password = "*****************************"; // use here password which is generated from WART tool

   WhatsApp wa = new WhatsApp(number, password, "Nickname", true); // nickname u can provide any name

            wa.OnConnectSuccess += () =>

            {

                Response.Write("connect");

                wa.OnLoginSuccess += (phoneNumber, data) =>

                {

                    Response.Write("connection successfully");

                    wa.SendMessage(to/* Number */, msg);

                    Response.Write("Sent Successfully");

                };

                wa.OnLoginFailed += (data) =>

                {

                    Response.Write("login failed" + data);

                };

                wa.Login();

            };

            wa.OnConnectFailed += (ex) =>

            {

                Response.Write("connection failed: {0}" + ex.StackTrace);

            };

            wa.Connect();

        }

Now you are ready to Send Message in Asp.Net Web Application through WhatsApp Application.
