Following documentation i put together this simple request. Every time i run this request i still get a 401 Authorization Required. I know the access token is fine because i use the same token using get to populate my models and it works fine it's only when i use post and place my token in the request headers.
Anyone else had this issue before?
     jQuery.ajax( {
        url: 'http://customer-server-2.dev/api/documents/add/.json',
        type: 'POST',
        data : {
             guid : $('.guid-input').val(),
             title : $('.title-input').val(),
             payload : $('.payload-input').val()
        },
        beforeSend : function( xhr ) {
            xhr.setRequestHeader( 'Authorization', 'BEARER ' +      app.AccessToken );
        },
        success: function( response ) {
            console.log(response);
        },
        error : function(error) {
            console.log(error);
        }
    } );
response header
