C# ADAL AcquireTokenAsync() without pop-up box

Question

We are writing a WCF service which has to integrate with Dynamics CRM 2016 Online. I\'m trying to authenticate using ADAL, using method AcquireTokenAsync(). Pro

Answer 1

private static string API_BASE_URL = "https://.com/";
private static string API_URL = "https://.com/api/data/v8.1/";
private static string CLIENT_ID = "";

static void Main(string[] args)
{
    var ap = AuthenticationParameters.CreateFromResourceUrlAsync(
                new Uri(API_URL)).Result;

    var authContext = new AuthenticationContext(ap.Authority, false);

    var userCredential = new UserCredential("", "");

    var result = authContext.AcquireToken(API_BASE_URL, CLIENT_ID, userCredential);

    var httpClient = HttpWebRequest.CreateHttp(Path.Combine(API_URL, "accounts"));
    httpClient.Headers.Add(HttpRequestHeader.Authorization, "Bearer:" + result.AccessToken);
    using (var sr = new StreamReader(httpClient.GetResponse().GetResponseStream()))
    {
        Console.WriteLine(sr.ReadToEnd());
    }
}

Note: I'm using an older version of ADAL (2.19.208020213) as it appears the password parameter has been taken out of the UserCredential constructor.

EDIT: Latest versions of ADAL have UserPasswordCredential which can be used in place of UserCredential (and probably was added as soon as Password was removed from UserCredential)

EDIT 2: CRM now supports Server to Server Authentication which allows you to create an application user.
