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\"}}"
