Hi 4Geeks Nation!! If you are behind a product development, specifically a mobile app, you want to know this new tool built by Google to send messages (notifications) to your users on your product.
Google launched Firebase Cloud Messaging (FCM) as a new and more powerful tool to manage messaging to mobile devices.
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 use cases such as instant messaging, a message can transfer a payload of up to 4KB to a client app.
Look at the FCM schema… it’s beautiful and useful.
