How to generate the request_token for zerodha api using C#

Zerodha Kite Api

How login Zerodha api using C# application?

Hi Friends, recently i have started create application for zerodha api to make my own client for trading.

Many of us have question how to login and trade using our custom C# application. I also face same problem i was looking solution for the same but  i was not able to fine exact way of doing it.

I have gone through zerodha api document 
According to them we need web view to make us to work this. Please follow be steps to get login token for API.

Steps :
1) Creaet your login URL which is kite login + API key
 eg.
  var kiteURL="https://kite.trade/connect/login?v=3&api_key="
   var apiKey="xpma3rmciorheitb"
   
2) Add web Browser to you web form set below properties

            webBrowser1.AllowNavigation = true;
            webBrowser1.ScriptErrorsSuppressed = true;
            webBrowser1.Navigate(new Uri(kiteURL+apiKey));

3) Now you need to register event "webBrowser1_DocumentCompleted"


private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            string[] list = webBrowser1.Url.ToString().Split("&".ToCharArray());
            foreach (string str in list)
            {
                string[] values = str.Split("=".ToCharArray());
                if (values[0].Contains("request_token"))
                {
                    requestToken = values[1];                  
                }
            }
        }

Now  You will be navigated to login page, Login using your User Name and Password if 2FA activate then pin might require.
After successful login you will see request token will be extracted.

if you are doing with console app or asp.net they you may need to add Windows form dll to you solution.
Dll Name: System.Windows.Forms.dll

Note: this is referring to Kite Version 3
