 CHANGELOG
 =========
 
+7.3
+---
+
+ * Changed to using the new v1 Firebase API
+ * [DEPRECATION] `AndroidNotification`, `IOSNotification` and `WebNotification` were deprecated and will be removed in 8.0, use `FirebaseOptions` instead. New Firebase API allows for all platform specific options to be specified for the message. Having options separated by platforms now limits usability.
+ * [DEPRECATION] Using DSN for firebase in the old format `firebase://username:password@default` was deprecated, use the new DSN format and specify the required options instead. Not specifying the options will throw error in 8.0.
+ * [DEPRECATION] `$token` param in `FirebaseTransport::__construct()` was marked as deprecated because the new Firebase API does not use standard token auth. The param will be removed in 8.0.
+

-FIREBASE_DSN=firebase://USERNAME:PASSWORD@default
+FIREBASE_DSN=firebase://<CLIENT_EMAIL>@default?project_id=<PROJECT_ID>&private_key_id=<PRIVATE_KEY_ID>&private_key=<PRIVATE_KEY>
+```
+
+All 4 parameters are required. All 4 parameters are located inside your firebase json private key.
+
+IMPORTANT: Make sure that `PRIVATE_KEY` is safely url encoded. Get more information in [Notifier documentation](https://symfony.com/doc/current/notifier.html#chat-channel) or use the script below.
+
+
+Getting credentials for your DSN
+--------------------------------
+
+Steps for getting your private key:
+ 1. Log into the [firebase console](https://console.firebase.google.com/).
+ 2. Click on your project
+ 3. Click on the gear icon next to "Project Overview" and click on "Project settings"
+ 4. Click on "Service accounts" tab
+ 5. Click on "Generate new private key" button at the bottom
+ 6. A JSON file with your private key will be downloaded
+
+The downloaded private key is a JSON file which should contain the following keys:
+ * `type`
+ * `project_id`
+ * `private_key_id`
+ * `private_key`
+ * `client_email`
+ * `client_id`
+ * `auth_uri`
+ * `token_uri`
+ * `auth_provider_x509_cert_url`
+ * `client_x509_cert_url`
+ * `universe_domain`
+
+You can then use the following script to convert your JSON private key to DSN format:
+
+```php
+<?php
+
+if (!isset($argv[1])) {
+    echo 'Usage: php ' . $argv[0] . ' path_to_your_key.json'.PHP_EOL;
+    exit(1);
+}
+
+$file = file_get_contents($argv[1]);
+
+if (false === $file) {
+    echo 'Could not open file at path: '.$argv[1].PHP_EOL.PHP_EOL;
+    exit(1);
+}
+
+$key = json_decode($file, true);
+
+if (false === $key) {
+    echo 'Unable to load JSON content of the file at path: '.$argv[1].PHP_EOL;
+    exit(1);
+}
+
+foreach (['client_email', 'project_id', 'private_key_id', 'private_key'] as $param) {
+    if (!isset($key[$param])) {
+        echo 'Missing param '.$param.' inside the JSON key.'.PHP_EOL;
+        exit(1);
+    }
+}
+
+echo sprintf(
+    'FIREBASE_DSN=firebase://%s@default?project_id=%s&private_key_id=%s&private_key=%s',
+    $key['client_email'],
+    $key['project_id'],
+    $key['private_key_id'],
+    urlencode($key['private_key']),
+).PHP_EOL;
+```
+
+The script then can be used as follows:
+```bash
+php script_name.php path/to/your/firebase/key.json
 ```
 
-where:
- - `USERNAME` is your Firebase username
- - `PASSWORD` is your Firebase password
 
 Adding Interactions to a Message
 --------------------------------
 
-With a Firebase message, you can use the `AndroidNotification`, `IOSNotification` or `WebNotification` classes to add
-[message options](https://firebase.google.com/docs/cloud-messaging/xmpp-server-ref.html).
+With a Firebase message, you can use the `FirebaseOptions` class to add
+[platform specific message options](https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#resource:-message).
+
+Specifying Firebase options for a message:
 
 ```php
 use Symfony\Component\Notifier\Message\ChatMessage;
-use Symfony\Component\Notifier\Bridge\Firebase\Notification\AndroidNotification;
+use Symfony\Component\Notifier\Bridge\Firebase\FirebaseOptions;
 
-$chatMessage = new ChatMessage('');
+$chatMessage = new ChatMessage('Hello, you should contribute to Symfony.');
 
-// Create AndroidNotification options
-$androidOptions = (new AndroidNotification('/topics/news', []))
-    ->icon('myicon')
-    ->sound('default')
-    ->tag('myNotificationId')
-    ->color('#cccccc')
-    ->clickAction('OPEN_ACTIVITY_1')
+// Specify options for Firebase
+$firebaseOptions = (new FirebaseOptions('/topics/news'))

 ```
 
+Firebase offers 3 different types of targets to send the message to:
+ * token
+ * topic
+ * condition
+
+How to specify different targets for firebase messages:
+
+```php
+use Symfony\Component\Notifier\Bridge\Firebase\FirebaseOptions;
+use Symfony\Component\Notifier\Bridge\Firebase\TargetType;
+
+// Use a topic as a target
+$topicOptions = new FirebaseOptions('/topics/news', targetType: TargetType::Topic);
+
+// Use a token as a target
+$tokenOptions = new FirebaseOptions('dU5e3nFJf9bE:APA91bH3Kd/exampleToken', targetType: TargetType::Token);
+
+// Use a condition as a target
+$conditionOptions = new FirebaseOptions('\'news\' in topics', targetType: TargetType::Condition);
+```
+
+Firebase also allows specifying platform specific options. They can be specified as follows:
+
+```php
+use Symfony\Component\Notifier\Bridge\Firebase\FirebaseOptions;
+use Symfony\Component\Notifier\Bridge\Firebase\TargetType;
+
+$detailedOptions = (new FirebaseOptions('dU5e3nFJf9bE:APA91bH3Kd/exampleToken', tergetType: TargetType::Token))

+        ],
+    ])
+    // WebPush specific options
+    ->webpush([
+        'notification' => [

+
+For all available options please refer to the [firebase documentation](https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages).
