Hi Joshua

Are you looking to use a UmbracoAuthorizedApiController in a backoffice dashboard or custom property editor ?

And then use the Angular.JS service $http.get to make a request to the API endpoint to return some JSON ?

If your controller class inherits from UmbracoAuthorizedApiController then in your ActionResult you will have access to the Umbraco Helper method via

Umbraco.

So you could create an end point like so that accepts the id of the node under which you want the descendants:

 public class MyLovelyController : UmbracoAuthorizedApiController
    {
        [HttpGet]
        public IEnumerable<SimplePocoClass> DescendantsOrSelf(int id)
        {

        var CurrentNode = Umbraco.TypedContent(id);
        if (CurrentNode != null)
        {
            return CurrentNode.DescendantsOrSelf().Select(f=>SimplifyObject(f));
        }
        else
        {
            return default(IEnumerable<SimplePocoClass>);

        }
    }
    //just to help serialise the response, you only want to return the properties you need
    private SimplePocoClass SimplifyObject(IPublishedContent content)
    {
        return new SimplePocoClass()
        {
            id = content.Id,
            Name = content.Name,
            OtherProperty = content.GetPropertyValue<string>("otherProperty")
        };
    } 

}
public class SimplePocoClass
{
    public int id { get; set; }
    public string Name { get; set; }
    public string OtherProperty { get; set; }

}

}

And in AngularJS, if you inject the 'editorState' umbraco service and '$http' angular service into your angularJS controller you can get the Id of the current node (eg where your property editor is loaded, if you are creating a property editor) and make the request to retrieve the data.

and use

var currentNodeId = editorState.current.id;
$http.get("/umbraco/backoffice/API/MyLovely/DescendantsOrSelf/" + currentNodeId).then(
    function (response) {
         $scope.mylovelydescendants = response.data;
});

if that helps ?
