Steps to get server key / SenderID
- To get the keys, log in to Firebase account.
- Select the project from the list.
- Click on "Setting" gear icon and click "Project Settings".
- Click on "Cloud Messaging" tab to select "Server key" and "Sender key" from the below screen.
Add the below code to send push notifications.
//Create the web request with fire base API
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
//serverKey - Key from Firebase cloud messaging server
tRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
//Sender Id - From firebase project setting
tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
tRequest.ContentType = "application/json";
var payload = new {
to = deviceId,
priority = "high",
content_available = true,
notification = new {
body = txtmsg,
title = txttitle.Replace(":", ""),
sound = "sound.caf",
badge = badgeCounter
},
};
var serializer = new JavaScriptSerializer();
Byte[] byteArray = Encoding.UTF8.GetBytes(payload);
tRequest.ContentLength = byteArray.Length;
using(Stream dataStream = tRequest.GetRequestStream()) {
dataStream.Write(byteArray, 0, byteArray.Length);
using(WebResponse tResponse = tRequest.GetResponse()) {
using(Stream dataStreamResponse = tResponse.GetResponseStream()) {
if (dataStreamResponse != null) using(StreamReader tReader = new StreamReader(ataStreamResponse)) {
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
