## Inbox Embed

The embedded components library now includes an **[Inbox](/ui/components/inbox)**, allowing you to add a full-featured messaging inbox directly into your website.

### What's new?

**Inbox embed**

Give your users a complete RCS and SMS messaging experience — conversations, message history, rich media, and real-time updates — all in a single iframe.

* Token-based authentication with scoped permissions
* Filter conversations by brand, sender, or simply show everything for a team
* Customizable colors with `primaryColor`
* Real-time message and conversation updates

**Send RCS Message updates**

[Send RCS Message](/ui/components/send-rcs-message) embed has been updated to use the new v2 token-based flow — message configuration is now securely encoded in the signed token on your backend.
