You can't cast type string as type MasterTab. I guess the WebApi service returns data in JSON format. Try to use Newtonsoft.Json to deserialize string response into MasterTab collection.

Either way, then we can call the ApiController directly from your MVC controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var listOfFiles = new MarketingController().GetMarketing();

        return View(listOfFiles);
    }
}

If we have our WebApi as a different project altogether in the same solution then we can call the same from MVC controller like below:

public async Task<ActionResult> Index()
        {
            string apiUrl = "http://localhost:58764/api/Marketing/GetMarketing";

            using (HttpClient client=new HttpClient())
            {
                client.BaseAddress = new Uri(apiUrl);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage response = await client.GetAsync(apiUrl);
                if (response.IsSuccessStatusCode)
                {
                    var data = await response.Content.ReadAsStringAsync();
                    EntityType entity = Newtonsoft.Json.JsonConvert.DeserializeObject<EntityType>(data);

                }


            }
            return View();

        }
