How do Facebook notifications work?
Facebook Notifications
Notifications are automatically handled by Facebook. Following are the two possibilities:
If schedule is created more than 15 minutes prior to the planned live stream
You have option to select how long before the start of your live stream you want to make an announcement on Facebook. e.g if your live stream is scheduled to go live after 20 min and you choose your event notification time as 15 min, then exactly 15 minutes before the live stream starts, Facebook will announce your planned live stream and it will appear in user's news feed. The following picture shows an example of how new stream announcement looks in your viewer's Facebook news feed.

Second notification will be sent by Facebook 3 minutes before your stream starts to all those Facebook users who have clicked Get Reminder button shown in the first announcement.
A third notification will be sent to some of your Facebook Page or Group followers (including those who clicked Get Reminder button) when the stream begins.
If schedule is created less than 15 minutes prior to the planned live stream
Facebook will send a notification to the Page or Group's followers as soon as the video live stream starts.
Due to recent changes made by Facebook, followers of a page may or may not receive notifications about a live stream on that page. By default a Facebook users is only shown notifications for a few selected posts on that page. This is determined by Facebook's own algorithms.
Your Page followers must edit their live video notifications settings for your page and make sure the notifications are set to All notifications. Otherwise, at times, they may not receive notifications when you go live. Page followers can follow these steps to edit the live video notification settings.
Go to the page and click on three dots. Select Follow Settings.

Under Notifications, click on Live video.

Change the settings to All Notifications.

Click Update.
