httpWebRequest.Headers.Add("X-Parse-REST-API-KEY", "my rest api key"); 
httpWebRequest.Method = "POST";

Bellow code is running for push notification using parse in .net.

private bool PushNotification(string pushMessage)
{
    bool isPushMessageSend = false;

    string postString = "";
    string urlpath = "https://api.parse.com/1/push";
    var httpWebRequest = (HttpWebRequest)WebRequest.Create(urlpath);
    postString = "{ \"channels\": [ \"Trials\"  ], " +
                     "\"data\" : {\"alert\":\"" + pushMessage + "\"}" +
                     "}";
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.ContentLength = postString.Length;
    httpWebRequest.Headers.Add("X-Parse-Application-Id", "My Parse App Id");
    httpWebRequest.Headers.Add("X-Parse-REST-API-KEY", "My Rest API Key");
    httpWebRequest.Method = "POST";
    StreamWriter requestWriter = new StreamWriter(httpWebRequest.GetRequestStream());
    requestWriter.Write(postString);
    requestWriter.Close();
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var responseText = streamReader.ReadToEnd();
        JObject jObjRes = JObject.Parse(responseText);
        if (Convert.ToString(jObjRes).IndexOf("true") != -1)
        {
            isPushMessageSend = true;
        }
    }

    return isPushMessageSend;
}

Thanks. This was very helpful. If you get a 400 Bad Request response from Parse, you may want to add a try/catch WebException handler to assist with debugging and error handling.

This is good. But if you get an error with "Bytes to be written to the stream exceed the Content-Length bytes size specified." when using special characters or non-latin characters then you might want to comment out/remove the "httpWebRequest.ContentLength = postString.Length;" part — HenrikP, Aug 18 '15 at 07:32

To send Notification to all app user you have to set the Data field like so:

postString = "{\"data\": { \"alert\": \"Test Notification 2 From Parse Via Chinwag Admin\" },\"where\": { \"deviceType\": \"ios\" }}";

Actually when you want to send a message to all users you have to use postString = "{ \"data\": { \"alert\": \"" + message + "\" } , \"where\" : { } }"; – Joost Schepel Jan 14 '16 at 12:45
