Facebook Pixel events are pieces of code sending additional information to Facebook. They can be fired on key actions, like page view, clicks, scroll, embedded video view, mouse over, etc.
Facebook has a number of Standard Events, but you can also configure your own Custom Events.
You can use events in various ways: optimize your ads, conversion tracking, Custom Audiences, Custom Conversions.
A Custom Event can only be used for Custom Audiences and Custom Conversions.

Almost any interaction can be captured by events. Here's a ClickEvent automatically fired on every click on our own website:
