Dear reader. It is a pleasure to communicate with you and begin this adventure in the world of Push Notifications.

Perhaps many agree with me when considering push notifications as a fantastic mechanism to deliver messages to the user. I think it to be one of the most versatile capabilities that mobile applications have. But let’s be honest, sometimes, during the implementation process of a feature that includes this ability, it can get more complicated than it should, either because the notification is not displayed, or that they suddenly stopped showing, or that they report a very strange bug and difficult to detect.

Thinking about it, I have good news for you, fellow readers. At the end of this book, you will agree with me that Push Notifications are an excellent mechanism to reach the user and that it is not so difficult after all to understand how they work and are implemented. In many cases, the answers are insight in the official documentation, but we get lost when putting all pieces together.

After many work sessions on this topic in mobile applications, I decided to share my knowledge. The two most important operating systems in mobile applications, iOS, and Android, are related. After all, what mobile application nowadays does not use Push Notifications in any of its functionalities?

Surely there will be a considerable percentage that still does not use these capabilities. Still, there is no doubt that it is a matter of time before they need to do so when they notice the multiple advantages they incorporate into an application.

Based on information collected from Firebase Cloud Messaging, Apple, Blogs, eBooks, and implementations in productive projects, I have organized each content so that the reader progressively acquires the fundamental concepts to develop later and implement each of these concepts.

If I can get the reader to include this manual in their reference documents, I feel that I have done my job on this topic.

Also, I encourage the reader to constantly check for updates and improvements in this field that are constantly evolving like the other fields.

I hope, reader friend, that you like this work and not being more, \"Let's start!\".
