How does Web Push Notification work?

Do you want to know how exactly web push notification works? To understand how push notification works, we need to know the different stages of web push notification. Since it’s a browser-based notification, the browser has to support the same for the web push notification to work. How do you get notifications from a website? To understand how notification comes from website to your browse, you need to understand the process behind it.

There are three stages of sending Web Push Notification:

Seeking permission to send the Push Message

Subscription Pop-up for push notification

The first step in implementing a push notification is to seek the permission of the user to send him a push message and getting a push subscription from the browser. With Subscription Dialog Box or Opt-in box, we ask users permission. A Push Subscription is done with a Push API that gives web applications the ability to receive messages pushed to them from a server. Once Push Subscription is received, the details are saved at the back-end and are later used to send push messages to that user.

Sending a Push Message

The push message is sent to the users via the PushEngage dashboard or through an  API call to a respective browser cloud manager – like GCM, APN, etc. The cloud manager validates and delivers the message to the right browser. The endpoint value in Push Subscription helps you get the appropriate URL to trigger the push message. In short, the push message is sent from your server to web notification service and the message arrives on the appropriate browser.

Push Message arrives on the User’s browser

Once the browser comes online, the push service delivers the message. The browser receives the message, decrypt the data, and sends push event to your service worker.
