Answer 1

You create a HttpClient object and set the header parameter

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost:64189/api/");
    
    //your header parameter name and value
    client.DefaultRequestHeaders.Add("hdrname", "hdrvalue"); 
    
    //HTTP GET
    var responseTask = client.GetAsync("youraction?param1=abc"); //Action Name
    responseTask.Wait();

    var result = responseTask.Result;
    if (result.IsSuccessStatusCode)
    {
        // Use your class model to receive the data from the API
        var readTask = result.Content.ReadAsAsync<IList<YourModel>>();
        readTask.Wait();

        var r = readTask.Result;
    }
    else //web api sent error response 
    {
        //log response status here..
    }
}
