# Introduction

Platform holds what every Footprint product shares once it is running in your stack: the events Footprint sends your backend, and the browser security policies your app must allow for a Footprint flow to load.

## What it does

* **Webhooks.** A POST to an endpoint you register in the dashboard when something happens in Footprint: an onboarding completes, a reviewer changes a user's status, a watchlist check finishes.
* **Content Security Policy.** The Permissions-Policy and Content-Security-Policy values your app needs so Footprint's domains and features can run inside it.

## Where to go next

[Webhooks](/articles/integrate/webhooks) lists the events and how to verify a signature. [Content Security Policy](/articles/integrate/content-security-policy) has the header values to copy.
