# Embedded Apps Overview

Embedded apps run directly inside the Seller Area as an iframe in the dashboard, with full access to the seller's store data via the [Store Admin API](/store-admin/introduction/getting-started).

## How apps work

When a seller opens your app, the Seller Area loads it in an iframe and provides a secure session. Your app authenticates with YouCan, obtains an access token, and can then read and write store data on behalf of the seller.

The [Qantra](/apps/developer-tools/qantra/overview) SDK handles communication between your iframe and the Seller Area — navigation, UI components, session tokens, and more.
