Cisco Spark Windows SDK

The Cisco Spark™ Windows SDK

The Cisco Spark Windows SDK makes it easy to integrate secure and convenient Cisco Spark calling and messaging features in your Windows applications.

This SDK is built with Vistual Studio 2017 and requires:

.NET Framework 4.5.2 or higher version
Win8 or Win10

Install

In your Windows application for example WPF project, here are steps to integrate the Cisco Spark Windows SDK into your project:

Right click your project, and select "Manage NuGet Packages..."
Search "Cisco.Spark.WindowsSDK" in the Browse tag
Install the lastest stable version

Usage

To use the SDK, you will need Cisco Spark integration credentials. If you do not already have a Cisco Spark account, visit the Cisco Spark for Developers portal to create your account and register an integration. Your app will need to authenticate users via an OAuth grant flow for existing Cisco Spark users or a JSON Web Token for guest users without a Cisco Spark account.

See the Windows SDK area of the Cisco Spark for Developers site for more information about this SDK.

Examples

Here are some examples of how to use the Windows SDK in your application. More details can be found under Windows SDK Demo app.

Create a new Spark instance using Spark ID authentication (OAuth-based):

string clientId = "your client id";  
string clientSecret = "your client secret";
string redirectUri = "KitchenSink://response/";
string scope = "spark:all";
var auth = new OAuthAuthenticator(clientId, clientSecret, scope, redirectUri);
// authCode(64 bits) can be extracted from url by loading auth.authorizationUrl with a WebBrowser
var spark = new SPARK(auth);
auth?.Authorize(authCode, result =>
{
    if (result.Success)
    {
        System.Console.WriteLine("authorize success!");
    }
    else
    {
        System.Console.WriteLine("authorize failed!");
    }
});

Create a new Spark instance using Guest ID authentication (JWT-based):

var auth = new JWTAuthenticator();
var spark = new SPARK(auth);
auth?.AuthorizeWith(jwt, result =>
{
    if (result.Success)
    {
        System.Console.WriteLine("authorize success!");
    }
    else
    {
        System.Console.WriteLine("authorize failed!");
    }
});

spark?.Phone.Register(result =>
{
    if (result.Success == true)
    {
        System.Console.WriteLine("spark cloud connected");
    }
    else
    {
        System.Console.WriteLine("spark cloud connect failed");
    }
});

Make an outgoing call:

// dial
// calleeAddress can be email address, person ID, or a room ID
spark?.Phone.Dial(calleeAddress, MediaOption.AudioVideoShare(curCallView.LocalViewHandle, curCallView.RemoteViewHandle, curCallView.RemoteShareViewHandle), result =>
{
    if (result.Success)
    {
        currentCall = result.Data;
        RegisterCallEvent();
    }
    else
    {
        System.Console.WriteLine($"Error: {result.Error?.errorCode.ToString()} {result.Error?.reason}");
    }
});

// register call event handlers
void RegisterCallEvent()
{
    currentCall.onRinging += CurrentCall_onRinging;
    currentCall.onConnected += CurrentCall_onConnected;
    currentCall.onDisconnected += CurrentCall_onDisconnected;
    currentCall.onMediaChanged += CurrentCall_onMediaChanged;
    currentCall.onCapabilitiesChanged += CurrentCall_onCapabilitiesChanged;
    currentCall.onCallMembershipChanged += CurrentCall_onCallMembershipChanged;    
}

// when video window such as local/remote/sharing window is resized or hided, call corresponding updateView with the windows handle
currentCall.UpdateLocalView(curCallView.LocalViewHandle);

Answer incoming call:

// register incoming call event
spark?.Phone.OnIncoming += Phone_onIncoming;

// get call object
void Phone_onIncoming(SparkSDK.Call obj)
{
    currentCall = obj;
}

// register call event handler and answer the call
RegisterCallEvent();

// answer current call  
currentCall?.Answer(MediaOption.audioVideo(curCallView.LocalViewHandle, curCallView.RemoteViewHandle), result =>
{
    if (!result.Success)
    {
        System.Console.WriteLine($"Error: {result.Error?.errorCode.ToString()} {result.Error?.reason}");
    }
});

Start a screen share

// Fetch all shareable desktop sources
this.currentCall.FetchShareSources(ShareSourceType.Desktop, result =>
{
    if (result.IsSuccess)
    {
        List<ShareSource> ShareSourceList = result.Data;
    }
});

// Fetch all shareable application sources
this.currentCall.FetchShareSources(ShareSourceType.Application, result =>
{
    if (result.IsSuccess)
    {
        List<ShareSource> ShareSourceList = result.Data;
    }
});

// Start share a selected share source.
this.currentCall.StartShare(sourceId, r =>
{
    if (r.IsSuccess)
    {
        System.Console.WriteLine("Start share success.");
    }
    else
    {
        System.Console.WriteLine($"Start share failed! Error: {r.Error?.ErrorCode.ToString()} {r.Error?.Reason}");
    }
});

Receive a screen share

// set share view handle when invoke dial method.
spark?.Phone.Dial(calleeAddress, MediaOption.AudioVideoShare(curCallView.LocalViewHandle, curCallView.RemoteViewHandle, curCallView.RemoteShareViewHandle), result =>
{});

// or set set share view handle when receive RemoteSendingShareEvent
currentCall.OnMediaChanged += CurrentCall_onMediaChanged;
private void CurrentCall_onMediaChanged(MediaChangedEvent mediaChgEvent)
{
    if (mediaChgEvent is RemoteSendingShareEvent)
    {
        var remoteSendingShareEvent = mediaChgEvent as RemoteSendingShareEvent;
        if (remoteSendingShareEvent.IsSending)
        {
            currentCall.SetRemoteShareView(curCallView.RemoteShareViewHandle);
        }
    }
}

Create a new Cisco Spark space, add a user to the space:

// Create a Cisco Spark room:
SparkSDK.Room room = null;
spark?.Rooms.Create("hello world", null, rsp =>
{
    if (rsp.Success){
        room = rsp.Data;
        System.Console.WriteLine("create space successfully");
    }
});

// Add a user to the room
spark?.Memberships.CreateByPersonEmail(room?.Id, "email address", false, rsp =>
{
    if (rsp.Success)
    {
        System.Console.WriteLine("add user successfully");
    }
});

// send message to the room
spark?.Messages.PostToRoom(room?.Id, "hello", null, rsp =>
{
    if(rsp.Success)
    {
        System.Console.WriteLine("post message successfully");
    }
});

Post a message

// Post a message to a person by email or person ID.
spark?.Messages.PostToPerson(toPerson, text, files, r =>
{
    if (r.IsSuccess)
    {
        Message message = r.Data;
        System.Console.WriteLine($"{message.PersonEmail} {message.Created}");
        System.Console.WriteLine($"{message.Text}");
    }
    else
    {
        System.Console.WriteLine($"send the message failed. {r.Error.ErrorCode} {r.Error.Reason}");
    }
});

// Post a message to a room by roomId.
spark?.Messages.PostToRoom(roomId, text, mentions, files, r =>
{
    if (r.IsSuccess)
    {
        Message message = r.Data;
        System.Console.WriteLine($"{message.PersonEmail} {message.Created}");
        System.Console.WriteLine($"{message.Text}");
    }
    else
    {
        System.Console.WriteLine($"send the message failed. {r.Error.ErrorCode} {r.Error.Reason}");
    }
});

Mention

// Mention list
List<Mention> Mentions = new List<Mention>();

// Mention All
Mentions.Add(new MentionAll());
spark?.Messages.PostToRoom(roomId, text, Mentions, files, r =>
{
    if (r.IsSuccess)
    {
        Message message = r.Data;
        System.Console.WriteLine($"{message.PersonEmail} {message.Created}");
        System.Console.WriteLine($"{message.Text}");
    }
    else
    {
        System.Console.WriteLine($"send the message failed. {r.Error.ErrorCode} {r.Error.Reason}");
    }
});

// Mention one person
Mentions.Add(new MentionPerson(personId));
spark?.Messages.PostToRoom(roomId, text, Mentions, files, r =>
{
    if (r.IsSuccess)
    {
        Message message = r.Data;
        System.Console.WriteLine($"{message.PersonEmail} {message.Created}");
        System.Console.WriteLine($"{message.Text}");
    }
    else
    {
        System.Console.WriteLine($"send the message failed. {r.Error.ErrorCode} {r.Error.Reason}");
    }
});

// Receive a Mention: See receive a message.

Receive a message

spark?.Messages.OnEvent += OnMessageEvent;
private void OnMessageEvent(MessageEvent e)
{
    if (e is MessageArrived)
    {
        System.Console.WriteLine("received a message.");
        var messageArrived = e as MessageArrived;
        var msgInfo = messageArrived?.Message;
        if (msgInfo != null)
        {
            // self is mentioned
            if (msgInfo.IsSelfMentioned)
            {
                System.Console.WriteLine($"{msgInfo.PersonEmail} mentioned you.");
            }

            System.Console.WriteLine($"{msgInfo.PersonEmail} {msgInfo.Created}");
            System.Console.WriteLine($"{msgInfo.Text}");

            // received attached files.
            if (msgInfo.Files != null && msgInfo.Files.Count > 0)
            {
                foreach (var file in msgInfo.Files)
                {
                    // download thumbnail if exist.
                    if (file.RemoteThumbnail != null)
                    {
