Facebook graph api: delete notification

Question

string sURL = "https://graph.facebook.com/" + _requestID + "?access_token=" + app.AccessToken + "&method=delete"; WebRequest request = WebRequest.Create(sURL); request.Method = "DELETE"; 

I use this code to remove apprequest. The request is removed from the list, but the notification still exists. Is there any way to remove it? Am I missing something when I can remove apprequest? Thanks

Verify that the final generated query is as follows:

 DELETE https://graph.facebook.com/ID?access_token=... HTTP/1.1 

Also make sure that you access_token really have access to user messages.
