How can I send a Firebase Cloud Messaging notification without use the Firebase Console?

I\'m starting with the new Google service for the notifications, Firebase Cloud Messaging.

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

1. send notifications to a Firebase User Identifier (UID) and
2. 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.
