Apps Overview

YouCan apps are embedded directly inside the Seller Area — they run in an iframe in the dashboard and have full access to the seller's store data via the Store Admin API.

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 SDK handles communication between your iframe and the Seller Area — navigation, UI components, session tokens, and more.
