i want sent push notification via parse.com , have webservice that

[webmethod] public bool pushnotification(string pushmessage) { bool ispushmessagesend = false;

    string poststring = "";     string urlpath = "https://api.parse.com/1/push";     //var httpwebrequest = (httpwebrequest)webrequest.create(urlpath);      system.net.webrequest request = system.net.httpwebrequest.create(urlpath);      request.usedefaultcredentials = true;      request.preauthenticate = true;      request.credentials = credentialcache.defaultcredentials;         poststring = "{ \"channels\": [ \"trials\"  ], " +                      "\"data\" : {\"alert\":\"" + pushmessage + "\"}" +                      "}";     request.contenttype = "application/json";     request.contentlength = poststring.length;     request.headers.add("app id", "my parse app id");     request.headers.add("rest api key", "my rest api key");     request.method = "post";     streamwriter requestwriter = new streamwriter(request.getrequeststream());     requestwriter.write(poststring);     requestwriter.close();     //var httpresponse = (httpwebresponse)request.getresponse();     system.net.webresponse response = request.getresponse();     using (var streamreader = new streamreader(response.getresponsestream()))     {         var responsetext = streamreader.readtoend();         jobject jobjres = jobject.parse(responsetext);         if (convert.tostring(jobjres).indexof("true") != -1)         {             ispushmessagesend = true;         }     }      return ispushmessagesend; }

i had error this

system.net.webexception: remote server returned error: (401) unauthorized.    @ system.net.httpwebrequest.getresponse()    @ webservice.pushnotification(string pushmessage) in c:\users\hurkan seyhan\desktop\website3\app_code\webservice.cs:line 488

how can solve problem?

according documentation (https://parse.com/docs/push_guide#sending-channels/rest) think mistake in headers

instead of

request.headers.add("[your app id]", "my parse app id"); request.headers.add("[your rest api key]", "my rest api key");

you should write following: 

request.headers.add("x-parse-application-id", "[your app id]"); request.headers.add("x-parse-rest-api-key", "[your rest api key]");
