According to this: http://msdn.microsoft.com/en-us/library/windowsazure/dn424880.aspx and this http://msdn.microsoft.com/en-us/library/windowsazure/hh974467.aspx

I should be able to do a get request

https://graph.windows.net/<my-object-guid>/tenantDetails?api-version=0.9

and I am using Fiddler just get started. Setting this in the composer: User-Agent: Fiddler Host: graph.windows.net Authorization: Bearer eyJ0eXA .... (My Token, used some c# from WAAL to get the token).

This is what is returned

HTTP/1.1 401 Unauthorized

{"odata.error":{"code":"Authentication_MissingOrMalformed","message":{"lang":"en","value":"Access Token missing or malformed."}}}

The token is accepted when I do some stuff in my application so I dont belive its malformed.

Answer 1

I kept running into this problem. I was using the following code to get a bearer token for my native app:

        var authContext = new AuthenticationContext("AUTHORITY");
        string token;
        try
        {
            var authresult = authContext.AcquireToken("MYAPP_ID","MYAPP_CLIENTID","MYAPP_REDIRECTURI");
            token = authresult.AccessToken;
        }

Using that token worked fine for authorizing actions within my own app, but I'd get the same error as the OP when trying to use the same token as authorization for the Graph API.

What I had to do was get a new token specifically for the Graph API - I used the same code as above but I used "https://graph.windows.net" instead of "MYAPP_ID" . So, to be clear, the following code gave me the correct OAuth token for the Graph API:

        var authContext = new AuthenticationContext("AUTHORITY");
        string token;
        try
        {
            var authresult = authContext.AcquireToken("https://graph.windows.net","MYAPP_CLIENTID","MYAPP_REDIRECTURI");
            token = authresult.AccessToken;
        }

Just make sure that your application registered in Azure has the necessary permissions to access your Azure domain's directory.
