# Overview

The Web Push protocol allows your application to easily engage users by sending notifications to the browser. The subscription to these notifications are done by the user (opt-in).

The notification types depend on the application. For example, it could be a notification for an internal message or an alert before account closure.

We will see in this documentation that the Web Push API offers several options to customize the notifications by adding buttons, vibration schema, images, urgency indictor and more.

You want to test it? Please go to [this demo page](https://serviceworke.rs/push-payload_demo.html) to see what your browser already supports.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://web-push.spomky-labs.com/3.1.x/common-concepts/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
