Authentication in Cortana Skills

Description

Cortana Skills can make calls to other services that require authentication, such as the Microsoft Graph. The easiest way to implement this for a service that requires OAuth 2.0 authentication is to configure a Connected Service for your skill and let Cortana manage the authentication token which is passed to your skill on invocation. Alternatively, you can manage the authentication entirely within your skills service which requires more work but gives greater flexibility. In this session, we’ll walk through how to configure a Connected Service and how to access the authentication tokens within your skill service to make authenticated calls, and we’ll cover how to implement skill-managed authentication.

    Sample code shown above for live connect APIs does not work as shown in video. I updated the code to use Microsoft Graph APIs.

    Here is the updated MessageRecievedAsync Method call -

     public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)
            {
                var message = await argument;
                var activity = await argument as Activity;
                string authAccessToken = String.Empty;
                string ShowText = String.Empty;
                string SpokenText = String.Empty;
                       
                    foreach (var entity in activity.Entities)
                    {
                        if(entity.Type == "AuthorizationToken")
                        {
                            dynamic authResult = entity.Properties;
                            authAccessToken = authResult.token;
                        }
                    }
                if (String.IsNullOrEmpty(authAccessToken))
                {
                    ShowText = "Error: Cortana did not send expected authorization token";
                    SpokenText = "Error invoking the Birthday Tracker. Cortana did not send the expected authorization token";
                }
                else
                {
                    //Use access token to get user info
                    //var url = "https://apis.live.net/v5.0/me?access_token=" + authAccessToken;
                    //var url = "https://graph.microsoft.com/v1.0/me?access_token=" + authAccessToken;
                    var url = "https://graph.microsoft.com/v1.0/me";
                    using (var client = new HttpClient())
                    {
                        client.DefaultRequestHeaders.Add("Authorization", "Bearer " + authAccessToken);
                        var response = await client.GetAsync(url);
                        if (!response.IsSuccessStatusCode)
                        {
                            //Api call failed, present an error to user
                            ShowText = "Failed to connect to profile with response code :" + response.ToString() + " Response phase" + response.ReasonPhrase.ToString() + "auth access token" + authAccessToken + "content" + response.Content.ToString();
                            SpokenText = "Sorry, I couldn\'t connect to your profile";
                        }
                        else
                        {
                            var responseString = await response.Content.ReadAsStringAsync();
                            //Extract usefule info from API response
                            dynamic data = JsonConvert.DeserializeObject(responseString);
                            try
                            {
                                //Extract useful info from API response
                                var givenName = (string)data.givenName;
                                var surName = (string)data.surname;
                                SpokenText = ShowText = $"Your name, {givenName} {surName}";
                                //var month = (int)data.birth_month;

    hi,
    how i can get oauth id token from cortana? i want to set openid scope and can get id token from cortana, but i don't fins any api i can use to get it.
    the id token from cortana is very useful to skill service, since most of time skill service need call other service to implement bussiness logic, if we can have id token in skill we can post the id token to other service. id token canbe used to validate the users and app information.
