Create subscription

Subscribes a listener application to receive change notifications when new messages are created for the user (that includes sent and received messages).

C# example

using System;
using System.Threading.Tasks;
using Independentsoft.Graph;
using Independentsoft.Graph.ChangeNotifications;

namespace ConsoleApp1
{
    class Program
    {
        static async Task Main()
        {
            try
            {
                GraphClient client = new GraphClient();

                client.ClientId = "63333333-209e-454e-b7bd-55a4d201270f";
                client.Tenant = "independentsoft.onmicrosoft.com";
                client.ClientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

                Subscription subscription1 = new Subscription();
                subscription1.ChangeTypes.Add(ChangeType.Created);
                subscription1.Resource = "/users/info@independentsoft.onmicrosoft.com/messages";
                subscription1.NotificationUrl = "https://webhook.site/9300d5df-9022-48ea-82ea-ca0809993db7";
                subscription1.ClientState = "123456789";
                subscription1.ExpirationTime = DateTime.Now.AddHours(1);

                Subscription createdSubscription = await client.CreateSubscription(subscription1);

                Console.WriteLine("Id: " + createdSubscription.Id);
                Console.WriteLine("ExpirationTime: " + createdSubscription.ExpirationTime);
            }
            catch (GraphException ex)
            {
                Console.WriteLine("Error: " + ex.Code);
                Console.WriteLine("Message: " + ex.Message);
                Console.Read();
            }
        }
    }
}
