host name who using my API controller in mvc 5

Question

IN MVC 5 PROJECT suppose I have API like

abc.com/authonication?userName=asdklfsdf&token=ASDF45FEWF312DFSFWE465SDF465

And some another web app (example.com) use this API

In my controller, I want to get the host name (example.com) of domain who using this API to validate

That's not how networks work. The request is issued from an IP address. You could do a reverse lookup to see which names are registered to that IP address, but that's not foolproof.

Is `example.com` calling your website from the client (the web browser) or the server (e.g. IIS)? — mjwills, Mar 07 '18 at 09:27

You can get some useful information from the HttpContext.Request field.

HttpContext.Request.UserHostAddress
HttpContext.Request.UserHostName

This information is not necessarily available, but in a lot of cases, it's there. Just don't depend on it.

As I said, it depends on many things, including the browser actually sending that information. Some browsers won't include it. For some requests, you WILL get the machine name, especially if you are trying it locally. – Neil Mar 07 '18 at 12:04

you can achieve this at your API Action method itself.

[HttpGet]
public object Add(string data = "")
{
    try
    {
        string result = "0";

        if (!string.IsNullOrEmpty(data))
        {
            var host = System.Web.HttpContext.Current.Request.UserHostName;
            var ip = System.Web.HttpContext.Current.Request.UserHostAddress;
        }

        return new { response = result };
    }
    catch (Exception ex)
    {
        throw ex;
    }
