NotificationHandler failing on AddSubscription

  • 1.  NotificationHandler failing on AddSubscription

    I'm updating my application to use PureCloudPlatform.Client.V2 v19.0.0 and ran into a snag when attempting to add a subscription to the Notification handler. Here's the code:

    Channel _channel = notificationsapi.PostNotificationsChannels(); var handler = new NotificationHandler(channel);

    handler.AddSubscription($"v2.users.{me.Id}.presence", typeof(UserPresenceNotification)); handler.AddSubscription($"v2.users.{me.Id}.conversations.calls", typeof(ConversationNotification));

    The logic fails at the first AddSubscription since the SDK's underlying PostNotificationsChannelSubscriptionsWithHttpInfo() fails since the Configuration.AccessToken is not set.

    How can I pass the Bearer token to this API if I'm using NotificationHandler ?

    Thanks Brian Alonso

    You need to authorize your application before creating NotificationHandler instances. See the section Using the Library in the documentation for information about authorizing using the SDK.

    Yes, the application is authorized and has the bearer token. However, the NotificationHandler does not have a Configuration Parameter like the NotificationsApi, so I'm not sure how to pass the NotificationHandler the bearer token

    The NotificationHandler uses the NotificationsApi. If you've authorized your application and the SDK can make API requests, so can the NotificationHandler. Here's my test app to confirm it works correctly:

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ININ.PureCloud.OAuthControl;
using Newtonsoft.Json;
using PureCloudPlatform.Client.V2.Api;
using PureCloudPlatform.Client.V2.Extensions.Notifications;
using PureCloudPlatform.Client.V2.Model;

namespace dotnetsdktest
{
    class Program7
    {
        [STAThread]
        static void Main(string[] args)
        {
            try
            {
                // Create form
                var form = new OAuthWebBrowserForm();

                // Set settings
                form.oAuthWebBrowser1.ClientId = "babbc081-0761-4f16-8f56-071aa402ebcb";
                form.oAuthWebBrowser1.RedirectUriIsFake = true;
                form.oAuthWebBrowser1.RedirectUri = "http://localhost:8080";

                // Open it
                var result = form.ShowDialog();

                Console.WriteLine($"Result: {result}");
                Console.WriteLine($"AccessToken: {form.oAuthWebBrowser1.AccessToken}");
                PureCloudPlatform.Client.V2.Client.Configuration.Default.AccessToken = form.oAuthWebBrowser1.AccessToken;

                var usersApi = new UsersApi();
                var _me = usersApi.GetUsersMe();

                var handler = new NotificationHandler();
                handler.AddSubscription($"v2.users.{_me.Id}.presence", typeof(UserPresenceNotification));
                handler.AddSubscription($"v2.users.{_me.Id}.conversations", typeof(ConversationNotification));
                handler.NotificationReceived += (data) =>
                {
                    Console.WriteLine(JsonConvert.SerializeObject(data, Formatting.Indented));

                    if (data.GetType() == typeof(NotificationData<UserPresenceNotification>))
                    {
                        var presence = (NotificationData<UserPresenceNotification>)data;
                        Console.WriteLine($"New presence: {presence.EventBody.PresenceDefinition.SystemPresence}");
                    }
                    else if (data.GetType() == typeof(NotificationData<ConversationNotification>))
                    {
                        var conversation = (NotificationData<ConversationNotification>)data;
                        Console.WriteLine($"Conversation: {conversation.EventBody.Id}");
                    }
                };

                Console.WriteLine("Websocket connected, awaiting messages...");
                Console.WriteLine("Press any key to remove conversations subscription.");
                Console.ReadKey(true);

                handler.RemoveSubscription($"v2.users.{_me.Id}.conversations");

                Console.WriteLine("Conversations subscription removed, awaiting messages...");
                Console.ReadKey(true);
            } catch (Exception ex)
            {
                Console.WriteLine(ex);
                Console.ReadKey(true);
            }
        }
    }
}

    Thanks, Tim.

    I was newing up a V2 config and setting the AccessToken as in the following:

    PureCloudPlatform.Client.V2.Client.Configuration _config = new PureCloudPlatform.Client.V2.Client.Configuration(); _config.AccessToken = bearerToken;

    Doing the following instead:

    PureCloudPlatform.Client.V2.Client.Configuration.Default.AccessToken = bearerToken;

    works fine.

    Thanks !

    Brian
