What are Web Push Notifications?
Web Push Notifications are clickable messages sent to users' devices- mobile, tablet, and desktop. The notifications will be sent only to subscribed users. Once users subscribe for the web push, they will start receiving notifications. It's not necessary for users to be on the website to receive web push. Web push notifications serve the purpose of bringing users back to the website.
How do Web Push Notifications work?
When users visit your website, they receive opt-in notification requesting their permission to receive notifications in future. When they click 'Allow', they are added to the list, and at the backend, the browser id gets automatically captured.
Once a visitor becomes a subscriber, you may start sending web push notifications based on the browser id. When web push notification is served to the user, the user sees the notification, clicks on it, and is redirected to the landing page.

Currently, all major browsers such as Chrome, Mozilla Firefox, Opera, and Safari support web push notification technology.

Explain Notification Expiry time. How can I set it for new notifications?
Notification Expiry time, referred to as Time-to-Live (TTL), is a value that allows you to define web push notification’s lifetime. For time-bound messages including count-down sale, flash sale, limited period offers, and breaking news, set notification expiry time in such a way that subscribers don't receive notifications after the specific time period of the sale or offer. You can set this value while creating new web push notification.
Can subscribers receive notifications when the browser is closed?
This varies from browser to browser and depends on how closely the browser interacts with the Operating System.

• For Firefox on Mac: Users can receive notifications when browser is closed provided browser is still running (indicated by '.' in menu).
• For Firefox on Windows: Users won’t receive notifications when browser is closed as the background process gets killed when window is closed.
