Hi brucey,

As far as I know, we will try the following two cases.

1: Use Web API

If you use Web API to implement this need. Your only difficulty is to ask this site provides an interface, then you can send data to this website and display the results back to your website.

Learn About ASP.NET Web API:

2: Simulation Website Login

This implementation is more cumbersome, because it has a lot of uncertainty.

You can refer the following post.

It's definitely not a recommended way to do it, but view the source of that page and look for the <form> tag.  As long as you submit to the same action, with the same field names, it should process like it was submitted from that site.  This is of course unless they have an anti forgery token on the page, which would make it impossible.

I have been looking at Ajax request in JavaScript, seems straightforward, has anyone every use Ajax to fire javascript to another website and then rip the html?

Hi brucey,

You can try the following code.

  protected void Button1_Click(object sender, EventArgs e)
        {

            string data = "Registration number=136260&Vehicle make=make name";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.check-mot.service.gov.uk/");//post url
            // set post headers
            request.Method = "POST";
            request.KeepAlive = true;
            request.ContentLength = data.Length;
            request.ContentType = "application/x-www-form-urlencoded";
            // write the data to the request stream         
            using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
            {
                writer.Write(data);
            }

            //get data and display the results back onto your website 
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            string myResponse = "";
            using (System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream()))
            {
                myResponse = sr.ReadToEnd();
            }

        }
