Creating & Targeting Firebase Audiences with Marketing Opt-In

Firebase's Audiences feature allows you to create user segments based on their behavior (app events) or user properties, which can then be used in Firebase Cloud Messaging to send personalized push notifications. This feature is supported from v3.7.7 of the Mobile App.

This article will show you how to ensure that you are only including users that have opted in to your marketing push notifications in your Audiences. This article only applies to brands that have GDPR opt-in enabled. You can find more information about that here.

To send push notifications to your entire user base, please see here.
