In-Process API not returning User join date and last visited date.

Steven, Thanks for the information. I tried the custom page URL. If the user logged in to the community they can able to view all the user info. else it's the same issue.
Now I worked on Exposing data to an external source. My extension not displaying Administrator-> extension section. Can you please help why it's not registered in Telligent?

public class SampleRestEndpoint : IRestEndpoints
    {
        public IEventLog eventLog = Telligent.Evolution.Extensibility.Apis.Get<IEventLog>();
        public void Initialize()
        {

            eventLog.Write("init rest", new EventLogEntryWriteOptions());
        }

        public string Name { get { return "Sample Rest Endpoint"; } }

        public string Description { get { return "Sample Rest Endpoint Description"; } }

        public void Register(IRestEndpointController restRoutes)
        {
            eventLog.Write("register rest", new EventLogEntryWriteOptions());
            restRoutes.Add(1, "test", null, null, Evolution.Extensibility.Rest.Version2.HttpMethod.Get, (IRestRequest,HttpResponse)=> { });
        }

    }

It would be expected that a user must be within the community site to view a routed page - and depending on the route implementation, would require an authenticated user to view content. For interacting with community content from an external location, REST API is the intended method - which then requires appropriate Authentication protocols.

To view your Rest endpoint plugin, either search for it in Administration search in upper left, or find it in Integration > Rest Apis.
