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    Get a view on following link  It will help you  https   firebase google com docs cloud-messaging send-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  amp  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

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    - gt withServiceAccount   path to firebase credentials json   - gt createMessaging      message   CloudMessage  withTarget    see sections below         - gt withNotification Notification  create  Title    Body        - gt withData   key    gt   value       messaging- gt send  message

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
