WEB API code how to consume it in ASP.Net MVC

Question

Hi All,
 
I have a question that I have a post method code in WEB API in which I need to consume it in MVC.
 

[HttpPost]
       [AllowAnonymous]
       [Route("NewVendorRegistration")]
       public IHttpActionResult InsertVendor()
       {
           //Passing Values in form data in PostMan

           var FirstName = HttpContext.Current.Request.Params["FirstName"];
           var LastName = HttpContext.Current.Request.Params["LastName"];
           var EmailId = HttpContext.Current.Request.Params["EmailId"];
           var MobileNo = HttpContext.Current.Request.Params["MobileNo"];
           var UserName = HttpContext.Current.Request.Params["UserName"];
           var Password = HttpContext.Current.Request.Params["Password"];
           var Address = HttpContext.Current.Request.Params["Address"];
           var IDProof = HttpContext.Current.Request.Params["IDProof"];
           var VendorPhoto = HttpContext.Current.Request.Files["VendorPhoto"];
           var CreatedBy = HttpContext.Current.Request.Params["CreatedBy"];

           if (FirstName != null && LastName != null && EmailId != null && MobileNo != null && UserName != null
               && Password != null && Address != null && IDProof !=null && CreatedBy != null)
           {

               string sReturn = string.Empty;
               SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString);
               SqlCommand cmd = new SqlCommand("spVendorRegistration", con);
               cmd.CommandType = CommandType.StoredProcedure;

               cmd.Parameters.AddWithValue("@QueryType", "Insert");
               cmd.Parameters.AddWithValue("@FirstName", FirstName.Trim());
               cmd.Parameters.AddWithValue("@LastName", LastName.Trim());
               cmd.Parameters.AddWithValue("@EmailId", EmailId.Trim());
               cmd.Parameters.AddWithValue("@MobileNo", MobileNo.Trim());
               cmd.Parameters.AddWithValue("@Address", Address.Trim());
               cmd.Parameters.AddWithValue("@IDProof", IDProof.Trim());
               cmd.Parameters.AddWithValue("@UserName",UserName.Trim());
               cmd.Parameters.AddWithValue("@Password", Password.Trim());
               cmd.Parameters.AddWithValue("@ActiveStatus", "Y");
               cmd.Parameters.AddWithValue("@CreatedBy", CreatedBy.Trim());
               if (VendorPhoto != null)
               {
                   IList AllowedFileExtensions = new List { ".jpg", ".jpeg", ".png" };
                   var ext = VendorPhoto.FileName.Substring(VendorPhoto.FileName.LastIndexOf('.'));
                   var extension = ext.ToLower();
                   if (!AllowedFileExtensions.Contains(extension))
                   {
                       VendorStr VendorData = new VendorStr
                       {
                           Response = "Please Upload image of type .jpg,.png.",
                           StatusCode = 0
                       };
                       return Ok(VendorData);
                   }

                   int MaxContentLength = 1024 * 1024 * 1; //Size = 1 MB

                   if (VendorPhoto.ContentLength > MaxContentLength)
                   {
                       var message = string.Format("Please Upload a file upto 1 mb.");

                       VendorStr VendorData = new VendorStr
                       {
                           Response = "Please Upload a file upto 1 mb.",
                           StatusCode = 0
                       };
                       return Ok(VendorData);
                   }

                   var filePath = HttpContext.Current.Server.MapPath("~/Images/Vendor/" + VendorPhoto.FileName);

                   if (File.Exists(filePath))
                   {
                       File.Delete(filePath);
                   }
                   VendorPhoto.SaveAs(filePath);
                   cmd.Parameters.AddWithValue("@VendorPhoto", filePath.Trim());
               }


               SqlParameter RuturnValue = new SqlParameter("@SQLReturn", SqlDbType.VarChar, 50);
               RuturnValue.Direction = ParameterDirection.Output;
               cmd.Parameters.Add(RuturnValue);
               con.Open();
               cmd.ExecuteNonQuery();
               sReturn = cmd.Parameters["@SQLReturn"].Value.ToString();
               string[] sResult = sReturn.Split('~');
               con.Close();

               if (sResult[0].Trim() == "Success")
               {
                   VendorStr Vendors = new VendorStr
                   {
                       Response = "Successfully Inserted",
                       StatusCode = 1
                   };
                   return Ok(Vendors);
               }
               else if (sResult[0].Trim() == "Already")
               {
                   VendorStr Vendors = new VendorStr
                   {
                       Response = sResult[1].Trim(),
                       StatusCode = 0
                   };
                   return Ok(Vendors);
               }
               else
               {
                   VendorStr Vendors = new VendorStr
                   {
                       Response = "Must Pass Correct Input Parameters",
                       StatusCode = 0
                   };
                   return Ok(Vendors);
               }
           }
           else
           {
               VendorStr Vendors = new VendorStr
               {
                   Response = "Must Pass All Parameters",
                   StatusCode = 0
               };
               return Ok(Vendors);
           }
       }

 
How I can consume this API Post method code in MVC and this code is in form data.
 
so if there's a solution please let me know it as soon as possible.
