This recipe provides an example of reading data from a Kumulos API method and reading the result into a local model object.

Ingredients

This recipe assumes that you have working knowledge of C# and an applicable toolchain (ASP.NET / Windows Phone / Xamarin).

Recipe

The process to read data from a Kumulos API method is:

• Create a new C# project with references to the Kumulos SDK binary and the Newtonsoft.Json Nuget package
• Instantiate a KumulosHttp client with your Api Key and Secret Key
• Call an API method
• Map the result payload to a local model object

using Kumulos.NET;
using System.Threading.Tasks;
using Newtonsoft.Json;
using Kumulos;
using System.Collections.Generic;

            foreach (KumulosObject obj in apiCall.Result) {
                optionTypesWOptions.Add(OptionTypeWithOptions.CreateOptionTypeWithOptionsFromKumulosObject(obj));
            }

            Console.WriteLine ("Results:");
            foreach (OptionTypeWithOptions optionType in optionTypesWOptions) {
