Firebase Cloud Messaging (FCM)

Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably deliver messages at no cost. Using FCM, you can notify a client app that new email or other data is available to sync. You can send notification messages to drive user re-engagement and retention. For instance, use FCM to notify your users that a new message or photo has been uploaded.

FCM is the new version of Google Cloud Messaging (GCM). It inherits the reliable and scalable GCM infrastructure, plus new features!

If you are using GCM client apps on iOS or Android, you can upgrade them to FCM without any changes on the client-side.

How FCM works?

FCM is a cross-platform messaging solution that allows you to send messages to Android, iOS and web clients through a single, unified API. It is the successor to Google Cloud Messaging (GCM) and is built on Google's Firebase platform.

FCM is free to use and offers a pay-as-you-go pricing model. There is no minimum spend and you only pay for the messages that are delivered.

To use FCM, you need to create a Firebase project and configure it for your app. Once that is done, you can send messages to your app clients through the Firebase console or using the FCM API.

FCM messages are delivered over HTTP or HTTPS to your app server, which then sends them to the client app. The client app can then display the message or take appropriate action.

FCM offers two types of messages:

Notification messages: These are messages that are displayed to the user. They can be displayed on the device's home screen, lock screen or notification tray.

Data messages: These are messages that are not displayed to the user. They can be used to trigger an action in the app, such as downloading a piece of content or opening a web page.

FCM messages are delivered to the app client through a process called push notification. When a message is sent, the FCM server first sends it to the Google Play services, which then delivers

In order to use FCM, you need to set up a Firebase project and register your app with the Firebase console. Once you have registered your app, you can obtain an FCM Server Key from the Firebase console. This key is used to authenticate your requests to the FCM server.

FCM is free for up to 4,000 messages per month. For more information, see the Firebase pricing page.
