 public class Notification
{
    private string serverKey = "kkkkk";
    private string senderId = "iiddddd";
    private string webAddr = "https://fcm.googleapis.com/fcm/send";

    public string SendNotification(string DeviceToken, string title ,string msg )
    {
        var result = "-1";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json";
        httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
        httpWebRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
        httpWebRequest.Method = "POST";

        var payload = new
        {
            to = DeviceToken,
            priority = "high",
            content_available = true,
            notification = new
            {

        var serializer = new JavaScriptSerializer();
        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))

            streamWriter.Write(json);
            streamWriter.Flush();

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

Here is my VbScript sample for who prefers vb:

//Create Json body
posturl="https://fcm.googleapis.com/fcm/send"
body=body & "{ ""notification"": {"
body=body & """title"": ""Your Title"","
body=body & """text"": ""Your Text"","
body=body & "},"
body=body & """to"" : ""target Token""}"

//Set Headers :Content Type and server key
set xmlhttp = server.Createobject("MSXML2.ServerXMLHTTP")
xmlhttp.Open "POST",posturl,false
xmlhttp.setRequestHeader "Content-Type", "application/json"
xmlhttp.setRequestHeader "Authorization", "Your Server key"

xmlhttp.send body
result= xmlhttp.responseText
//response.write result to check Firebase response
Set xmlhttp = nothing

I don't believe there is any change in the way you are sending push notifications. In FCM also, you are going to make HTTP POST Request the same way you did for GCM:

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

Read about FCM Server for more information.

The only change I could see now, is the target Url. Period.
