 A **Card Message** is a structured, interactive message rendered as a card bubble inside a conversation. Cards are **receive-only** on the SDK: they are created through the **Platform REST API** or the **Dashboard Bubble Builder** and delivered to clients like any other message — the SDK does not send them.

Card Messages are created server-side via the **Platform REST API** or the **Dashboard Bubble Builder**, and delivered to clients like any other message.
