Meet Automatically Collected Events

Automatically Collected Events  are automatically collected by the system without additional settings, as long as you have the Google Analytics for Firebase SDK or gtag.js installed, and basic user interactions with your app/website.

Automatically Collected Events do not count towards the 500 event limit.

Automatically Collected Events Categories

Because of different device types, Automatically Collected Events are also different and can be divided into two categories, Web and APP.
