Firebase Cloud Messaging (FCM) is a cross-platform messaging service provided by Firebase that allows you to send and receive messages across Android, iOS, and the web. It is designed to help you engage and retain users by providing a reliable and efficient way to send targeted, personalized messages to users in real-time.
FCM allows you to send messages to users either individually or in groups, and supports a variety of message types, including notification messages, data messages, and topic messages. You can use FCM to send messages from your app server or from the Firebase console, and FCM handles the delivery and display of the messages on the user’s device.
FCM integrates with other Firebase services, such as Realtime Database and Cloud Firestore, allowing you to trigger messages based on changes to your data or other events. It also integrates with a number of third-party tools and platforms, such as AdWords and AppsFlyer, allowing you to connect your messaging campaigns with your advertising and marketing efforts.
Overall, FCM is a powerful and reliable messaging service that can help you engage and retain users by delivering targeted, personalized messages in real-time.
