# Embed Overview

Cloutly Embed lets you render the Cloutly app in your product using an iframe while your backend controls auth and tenancy through signed JWT claims.

## Core flow

1. Your frontend requests an embed JWT from your backend.
2. Your backend signs a short-lived token with your Cloutly signing key.
3. Cloutly validates the token, then upserts user and business records.
4. The iframe session loads in the scoped business context.
