I am working on a push notification in android with PHP ( using fcm), Push notification is working fine but I am not getting any push notification whenever my App is "closed" (I am getting notification only whenever my app is "open")
Here is my code, where I am wrong?
function testingPush(){
define("FCM_URL", "https://fcm.googleapis.com/fcm/send");
define( "FCM_KEY","xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
$devicetype1 = "ios";
$devicetype2 = "android";
$deviceType = $rows['device_type']; // coming from database
$deviceToken = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$titleMessage="Push Notification Testing";
$message="Lorem Ipsum";
$msgs = array();
if (strcasecmp($devicetype1, $deviceType) == 0)
{
/* sending push to IOS */
$notification = array('body'=>$message,
'sound'=>"default",
'title'=>$titleMessage,
'badge'=>1);
$data = array('notificationType'=>1,
'displayURL'=>"https://upload.wikimedia.org/wikipedia/commons/thumb/2/2a/FloorGoban.JPG/1024px-FloorGoban.JPG");
$msgs = array('to'=>$deviceToken,
'content_available'=>true,
'mutable_content'=>true,
'notification'=>$notification,
'priority'=>'high',
'data'=>$data);
}
else{
/* sening push to android */
$notification = array('contentTitle'=>$titleMessage,
'message'=>$message);
$msgs = array('to'=>$deviceToken,
'priority'=>'high',
'data'=>$notification);
}
$this->sendPushNotification_With($msgs);
}
private function sendPushNotification_With($json) {
$headers = array('Authorization: key=' . FCM_KEY,'Content-Type: application/json');
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, FCM_URL );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode($json) );
$result = curl_exec($ch );
curl_close( $ch );
}
Well I think the problem is contentTitle in $notification , replace it to title and it should work and also in your ios notification you are using notification as seperate variable, I would rather suggest you to pass the notification paramter in data , as notification don't work in background.If above don't work recheck your key
I created some PHP code that gets a GCM register from the database and sends a push to an Android device. This code works ok, but when the user deletes the app on Android for example the GCM register in the database gets invalid.
How do I know when the GCM register is invalid in order to delete it from the database using PHP?
This is the code that sends push:
//Getting api key
$api_key = "....";
//Getting registration token we have to make it as array
$reg_token = array($token);
//Getting the message
$message = $versiculo;
//Creating a message array
$msg = array
(
'message' => $message,
'title' => $capitulo,
'id_versiculo' => $id,
);
//Creating a new array fileds and adding the msg array and registration token array here
$fields = array
(
'registration_ids' => $reg_token,
'data' => $msg
);
//Adding the api key in one more array header
$headers = array
(
'Authorization: key=' . $api_key,
'Content-Type: application/json'
);
//Using curl to perform http request
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
//Getting the result
$result = curl_exec($ch );
curl_close( $ch );
When the client app is uninstalled, the corresponding token will be invalidated, where if you send a message to that specific token, it would return a NotRegistered error, in which case you can delete (or archive) that token.
As mentioned in the comments, please proceed to migrate your app to FCM, as Google already provided a notice of deprecation (see my answer here).
For FCM, the behavior is actually the same. See this similar/possibly duplicate post.
I'm starting with the new Google service for the notifications, Firebase Cloud Messaging.
Thanks to this code https://github.com/firebase/quickstart-android/tree/master/messaging I was able to send notifications from my Firebase User Console to my Android device.
Is there any API or way to send a notification without use the Firebase console? I mean, for example, a PHP API or something like that, to create notifications from my own server directly.
Firebase Cloud Messaging has a server-side APIs that you can call to send messages. See https://firebase.google.com/docs/cloud-messaging/server.
Sending a message can be as simple as using curl to call a HTTP end-point. See https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol
curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" \
--Header "Content-Type: application/json" \
https://fcm.googleapis.com/fcm/send \
-d "{\"to\":\"<YOUR_DEVICE_ID_TOKEN>\",\"notification\":{\"title\":\"Hello\",\"body\":\"Yellow\"}}"
You can all this REST API from within any environment, but there are dedicated so-called Admin SDKs for many platforms listed here.
This works using CURL
function sendGCM($message, $id) {
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'registration_ids' => array (
$id
),
'data' => array (
"message" => $message
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "YOUR_KEY_HERE",
'Content-Type: application/json'
);
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, true );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $fields );
$result = curl_exec ( $ch );
echo $result;
curl_close ( $ch );
}
?>
$message is your message to send to the device
$id is the devices registration token
YOUR_KEY_HERE is your Server API Key (or Legacy Server API Key)
Use a service api.
URL: https://fcm.googleapis.com/fcm/send
Method Type: POST
Headers:
Content-Type: application/json
Authorization: key=your api key
Body/Payload:
{
"notification": {
"title": "Your Title",
"text": "Your Text",
"click_action": "OPEN_ACTIVITY_1"
},
"data": {
"<some_key>": "<some_value>"
},
"to": "<device_token>"
}
And with this in your app you can add below code in your activity to be called:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Also check the answer on Firebase onMessageReceived not called when app in background
Examples using curl
Send messages to specific devices
To send messages to specific devices, set the to the registration token for the specific app instance
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send
Send messages to topics
here the topic is : /topics/foo-bar
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "to": "/topics/foo-bar","data": { "message": "This is a Firebase Cloud Messaging Topic Message!"}}' https://fcm.googleapis.com/fcm/send
Send messages to device groups
Sending messages to a device group is very similar to sending messages to an individual device. Set the to parameter to the unique notification key for the device group
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{"to": "<aUniqueKey>","data": {"hello": "This is a Firebase Cloud Messaging Device Group Message!"}}' https://fcm.googleapis.com/fcm/send
Examples using Service API
API URL : https://fcm.googleapis.com/fcm/send
Headers
Content-type: application/json
Authorization:key=<Your Api key>
Request Method : POST
Request Body
Messages to specific devices
{
"data": {
"score": "5x1",
"time": "15:10"
},
"to": "<registration token>"
}
Messages to topics
{
"to": "/topics/foo-bar",
"data": {
"message": "This is a Firebase Cloud Messaging Topic Message!"
}
}
Messages to device groups
{
"to": "<aUniqueKey>",
"data": {
"hello": "This is a Firebase Cloud Messaging Device Group Message!"
}
}
As mentioned by Frank, you can use Firebase Cloud Messaging (FCM) HTTP API to trigger push notification from your own back-end. But you won't be able to
send notifications to a Firebase User Identifier (UID) and
send notifications to user segments (targeting properties & events like you can on the user console).
Meaning: you'll have to store FCM/GCM registration ids (push tokens) yourself or use FCM topics to subscribe users. Keep also in mind that FCM is not an API for Firebase Notifications, it's a lower-level API without scheduling or open-rate analytics. Firebase Notifications is build on top on FCM.
Introduction
I compiled most of the answers above and updated the variables based on the FCM HTTP Connection Docs to curate a solution that works with FCM in 2021. Credit to Hamzah Malik for his very insightful answer above.
Prerequisites
First, ensure that you have connected your project with Firebase and that you have set up all dependencies on your app. If you haven't, first head over to the FCM Config docs
If that is done, you will also need to copy your project's server response key from the API. Head over to your Firebase Console, click on the project you're working on and then navigate to;
Project Settings(Setting wheel on upper left corner) -> Cloud Messaging Tab -> Copy the Server key
Configuring your PHP Backend
I compiled Hamzah's answer with Ankit Adlakha's API call structure and the FCM Docs to come up with the PHP function below:
function sendGCM() {
// FCM API Url
$url = 'https://fcm.googleapis.com/fcm/send';
// Put your Server Response Key here
$apiKey = "YOUR SERVER RESPONSE KEY HERE";
// Compile headers in one variable
$headers = array (
'Authorization:key=' . $apiKey,
'Content-Type:application/json'
);
// Add notification content to a variable for easy reference
$notifData = [
'title' => "Test Title",
'body' => "Test notification body",
'click_action' => "android.intent.action.MAIN"
];
// Create the api body
$apiBody = [
'notification' => $notifData,
'data' => $notifData,
"time_to_live" => "600" // Optional
'to' => '/topics/mytargettopic' // Replace 'mytargettopic' with your intended notification audience
];
// Initialize curl with the prepared headers and body
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url );
curl_setopt ($ch, CURLOPT_POST, true );
curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ($ch, CURLOPT_POSTFIELDS, json_encode($apiBody));
// Execute call and save result
$result = curl_exec ( $ch );
// Close curl after call
curl_close ( $ch );
return $result;
}
Customizing your notification push
To submit the notifications via tokens, use 'to' => 'registration token'
What to expect
I set up the function in my website back-end and tested it on Postman. If your configuration was successful, you should expect a response similar to the one below;
{"message":"{"message_id":3061657653031348530}"}
this solution from this link helped me a lot. you can check it out.
The curl.php file with those line of instruction can work.
<?php
// Server key from Firebase Console define( 'API_ACCESS_KEY', 'AAAA----FE6F' );
$data = array("to" => "cNf2---6Vs9", "notification" => array( "title" => "Shareurcodes.com", "body" => "A Code Sharing Blog!","icon" => "icon.png", "click_action" => "http://shareurcodes.com"));
$data_string = json_encode($data);
echo "The Json Data : ".$data_string;
$headers = array ( 'Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json' );
$ch = curl_init(); curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_POSTFIELDS, $data_string);
$result = curl_exec($ch);
curl_close ($ch);
echo "<p> </p>";
echo "The Result : ".$result;
Remember you need to execute curl.php file using another browser ie not from the browser that is used to get the user token. You can see notification only if you are browsing another website.
First you need to get a token from android and then you can call this php code and you can even send data for further actions in your app.
<?php
// Call .php?Action=M&t=title&m=message&r=token
$action=$_GET["Action"];
switch ($action) {
Case "M":
$r=$_GET["r"];
$t=$_GET["t"];
$m=$_GET["m"];
$j=json_decode(notify($r, $t, $m));
$succ=0;
$fail=0;
$succ=$j->{'success'};
$fail=$j->{'failure'};
print "Success: " . $succ . "<br>";
print "Fail : " . $fail . "<br>";
break;
default:
print json_encode ("Error: Function not defined ->" . $action);
}
function notify ($r, $t, $m)
{
// API access key from Google API's Console
if (!defined('API_ACCESS_KEY')) define( 'API_ACCESS_KEY', 'Insert here' );
$tokenarray = array($r);
// prep the bundle
$msg = array
(
'title' => $t,
'message' => $m,
'MyKey1' => 'MyData1',
'MyKey2' => 'MyData2',
);
$fields = array
(
'registration_ids' => $tokenarray,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
return $result;
}
?>
Works in 2020
$response = Http::withHeaders([
'Content-Type' => 'application/json',
'Authorization'=> 'key='. $token,
])->post($url, [
'notification' => [
'body' => $request->summary,
'title' => $request->title,
'image' => 'http://'.request()->getHttpHost().$path,
],
'priority'=> 'high',
'data' => [
'click_action'=> 'FLUTTER_NOTIFICATION_CLICK',
'status'=> 'done',
],
'to' => '/topics/all'
]);
Here is the working code in my project using CURL.
<?PHP
//Avoid keys confusions!
//firebase Cloud Messaging have 3 different keys:
//API_KEY, SERVER_KEY and PUSH_KEY ... here we need SERVER_KEY
// SERVER access key from Google firebase Console
define( 'SERVER_ACCESS_KEY', 'YOUR-SERVER-ACCESS-KEY-GOES-HERE' );
$registrationIds = array( $_GET['id'] );
// prep the bundle
$msg = array
(
'message' => 'here is a message. message',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',

You can use for example a PHP script for Google Cloud Messaging (GCM). Firebase, and its console, is just on top of GCM.
I found this one on github:
https://gist.github.com/prime31/5675017
Hint: This PHP script results in a android notification.
Therefore: Read this answer from Koot if you want to receive and show the notification in Android.
Notification or data message can be sent to firebase base cloud messaging server using FCM HTTP v1 API endpoint.
https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send.
You need to generate and download private key of service account using Firebase console and generate access key using google api client library. Use any http library to post message to above end point, below code shows posting message using OkHTTP. You can find complete server side and client side code at firebase cloud messaging and sending messages to multiple clients using fcm topic example
If a specific client message needs to sent, you need to get firebase registration key of the client, see sending client or device specific messages to FCM server example
String SCOPE = "https://www.googleapis.com/auth/firebase.messaging";
String FCM_ENDPOINT
= "https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send";
GoogleCredential googleCredential = GoogleCredential
.fromStream(new FileInputStream("firebase-private-key.json"))
.createScoped(Arrays.asList(SCOPE));
googleCredential.refreshToken();
String token = googleCredential.getAccessToken();
final MediaType mediaType = MediaType.parse("application/json");
OkHttpClient httpClient = new OkHttpClient();
Request request = new Request.Builder()
.url(FCM_ENDPOINT)
.addHeader("Content-Type", "application/json; UTF-8")
.addHeader("Authorization", "Bearer " + token)
.post(RequestBody.create(mediaType, jsonMessage))
.build();
Response response = httpClient.newCall(request).execute();
if (response.isSuccessful()) {
log.info("Message sent to FCM server");
}
Go to cloud Messaging select: Server key
function sendGCM($message, $deviceToken) {
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'registration_ids' => array (
$id
),
'data' => array (
"title" => "Notification title",
"body" => $message,
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "YOUR_SERVER_KEY",
'Content-Type: application/json'
);
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, true );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $fields );
$result = curl_exec ( $ch );
echo $result;
curl_close ($ch);
}
Or you can use Firebase cloud functions, which is for me the easier way to implement your push notifications.
firebase/functions-samples
If you're using PHP, I recommend using the PHP SDK for Firebase: Firebase Admin SDK. For an easy configuration you can follow these steps:
Get the project credentials json file from Firebase (Initialize the sdk) and include it in your project.
Install the SDK in your project. I use composer:
composer require kreait/firebase-php ^4.35
Try any example from the Cloud Messaging session in the SDK documentation:
use Kreait\Firebase;
use Kreait\Firebase\Messaging\CloudMessage;
$messaging = (new Firebase\Factory())
->withServiceAccount('/path/to/firebase_credentials.json')
->createMessaging();
$message = CloudMessage::withTarget(/* see sections below */)
->withNotification(Notification::create('Title', 'Body'))
->withData(['key' => 'value']);
$messaging->send($message);
If you want to send push notifications from android check out my blog post
Send Push Notifications from 1 android phone to another with out server.
sending push notification is nothing but a post request to https://fcm.googleapis.com/fcm/send
code snippet using volley:
JSONObject json = new JSONObject();
try {
JSONObject userData=new JSONObject();
userData.put("title","your title");
userData.put("body","your body");
json.put("data",userData);
json.put("to", receiverFirebaseToken);
}
catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest("https://fcm.googleapis.com/fcm/send", json, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.i("onResponse", "" + response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Authorizationey=" + SERVER_API_KEY);
params.put("Content-Typepplication/json");
return params;
}
};
MySingleton.getInstance(context).addToRequestQueue(jsonObjectRequest);
I suggest you all to check out my blog post for complete details.
Using Firebase Console you can send message to all users based on application package.But with CURL or PHP API its not possible.
Through API You can send notification to specific device ID or subscribed users to selected topic or subscribed topic users.

i received GCM registration token for my device but when i am sending message using REST api from PHP, it shows Success but not receving message on device. php code
<?php
$data = array( 'message' => 'Hello World! First Message from PHP' );
$ids = 'device registration token';
// Send a GCM push
sendGoogleCloudMessage( $data, $ids );
function sendGoogleCloudMessage( $data, $ids )
{
// Insert real GCM API key from Google APIs Console
// https://code.google.com/apis/console/
$apiKey = 'API Key'; //(server API Key)
// Define URL to GCM endpoint
$url = 'https://gcm-http.googleapis.com/gcm/send';
// Set GCM post variables (device IDs and push payload)
$post = array(
'to' => $ids,
'data' => $data,
);
// Set CURL request headers (authentication and type)
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Initialize curl handle
$ch = curl_init();
// Set URL to GCM endpoint
curl_setopt( $ch, CURLOPT_URL, $url );
// Set request method to POST
curl_setopt( $ch, CURLOPT_POST, true );
// Set our custom headers
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
// Get the response back as string instead of printing it
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
// Set JSON post data
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $post ) );
// Actually send the push
$result = curl_exec( $ch );
// Error handling
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
// Close curl handle
curl_close( $ch );
// Debug GCM response
echo $result;
print_r($result);
}
?>
while submitting PHP file, it returns message as below, it seems message shows 'success' but no message received at device. can someone suggest if i need to take additional step or doing something wrong?
{"multicast_id":8550022549195779350,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1459795352923689%21f96bfff9fd7ecd"}]}
Be sure that your API key is correct, and that your server IP is listed as trusted by the certificate. Sometimes, WiFi connected devices become unresponsive to GCM after a while. Try to restart your device. It should start receiving all the messages you have sent.
Also, from this SO question, check if you mistakenly used android:permission="com.google.android.gcm.c2dm.permission.SEND" instead of android:permission="com.google.android.c2dm.permission.SEND".
Hope this helps!
