App Bridge

Embed your application directly in the Cartly merchant admin using iframe-based integration.

Architecture

App Bridge apps run inside an iframe within the Cartly admin panel. Communication between your app and the Cartly admin happens via postMessage.

Session Tokens

When your app loads in the iframe, Cartly provides a session token via query parameter. Use this token to authenticate API requests on behalf of the merchant.
