The current project I'm working on requires me to talk with the windows live API. I use an AJAX request to receive a JSON object with the user details.
How ever I keep getting this error:
Failed to load resource: the server responded with a status of 415 (Unsupported Media Type)

My first idea was to add a &callback=? the url. But then I get Uncaught SyntaxError: Unexpected token : in the JSON response.

I've been searching on how I could fix the error(s). But found no working solution for both errors. On top if that I'm quite unsure which error I should try solving (status 415 or unexpected token). Anything pointing me in the right direction would be greatly appreciated!

$.ajax({

        url: https://apis.live.net/v5.0/me?access_token= + localStorage.getItem('Live_token'),

        dataType: 'json',

        type : 'GET',

        contentType: application/json;,

        async: false,

        success : function(data) {

            var id = data.id,

            fname = data.last_name,

            email = data.emails.preferred;//TODO preferred or account?

            alert(id + '|' + fname + '|' + email);

            localStorage.setItem('Live_verifier', id + '|' + fname + '|' + email);

        },

        error : function(data) {

            localStorage.removeItem('Live_token');

        }

    });

thanks in advance
