## Overview

Starting with Flex UI 2.13.0, use the Flex UI Actions framework to send a [content template](/docs/content) to agents and customers during a conversation. When you send a content template programmatically, Flex adds the message to the conversation history alongside other agent and customer messages.

Note that you can't filter by agent or otherwise select which conversations receive content templates that you send programmatically. The message appears in all active conversations in the channel.

Currently, you can send content templates only on the WhatsApp channel.

## `SendRichContentMessage` UI action

To send a content template programmatically, use the `SendRichContentMessage` action. This action is different from the `SendMessage` action because `SendMessage` uses the `body` property, while `SendRichContentMessage` uses the `contentSid` parameter and the `contentVariables` parameter (if applicable) to define the message content.

For a full list of properties available and examples of the `SendRichContentMessage` action, refer to the [Flex UI API Reference](https://assets.flex.twilio.com/docs/releases/flex-ui/latest/ui-actions/Actions/#SendRichContentMessage). The `SendRichContentMessage` action is available in Flex UI 2.13.0 and later.
