Question

I’m logged in using to my own Application using C# Facebook SDK and I can read/write/delete all data I need.

However for validation purposes I’d like to get AppID that I’m currently using (the one I used when generating login Uri) based on existing valid Access-token and Facebook.FacebookClient object.

In a similar way like in Facebook PHP SDK: $appId = Facebook->getAppId();

My access token is not like string.Concat(appId, "|", appSecret)

Answer 1

If I use Facebook C# Sdk I may use following code to retrieve appID I used when loging in – if at the moment I have in memmory only AccessToken available:

string myAccessToken = "...";
FacebookClient fc = new FacebookClient(myAccessToken);
IDictionary<string, object> resultContainer = 
          (IDictionary<string, object>)fc.Get("/app");
string retrievedAppID = resultContainer["id"] as string;

The same result can be obtained directly from Graph Api Explorer via:

https://graph.facebook.com/app

If desired Facebook application is selected at top right part of the Graph Api Explorer page.
