ESI API Authentication

I am trying my hands to the ESI api.

When I am trying to get basic information about players Stations
https://esi.tech.ccp.is/latest/universe/structures/1024235980117/?datasource=tranquility


I get requested with authentication.

As far as I can see, the data returned by this call is nothing critical (name, location,...), so what's the point of the authentication?

I have registered my application with EVE Developers so now I have a client ID and secret key.
How do I use them from C#?

So far this is what I am doing:


string link = "https://esi.tech.ccp.is/latest/markets/10000032/orders/?datasource=tranquility&order_type=all&page=1&type_id=2329";
HttpWebRequest apiRequest;
apiRequest = (HttpWebRequest)WebRequest.Create(link);

apiRequest.Credentials = null;
apiRequest.UseDefaultCredentials = false;
apiRequest.UserAgent = "EVE Planetary Planner";

apiRequest.UserAgent = @"Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4";
using (HttpWebResponse apiResponse = (HttpWebResponse)apiRequest.GetResponse())
{
    Stream dataStream = apiResponse.GetResponseStream();
    StreamReader reader = new StreamReader(dataStream);
    string strResponse = reader.ReadToEnd();
    // do things here
}


Can someone show me an example of how to use the EVE Developers credentials? or point me to a tutorial?

Thanks

Also, what is the use of the callback URL?
How does it work with a C# application?
This was not clear when I registered my application, so I just put 'eveauth-app://callback/' to have something there...

It requires authorization because it will only work on structures that you have access to, ie are on the ACL.

After authentication the user will be redirected to this URL on your website. It must match the definition on file in the developers site.

I have no idea. Have to have someone with C# exp help you there or figure it out yourself.
