# Interaction Channel Participants

> \[!NOTE]
>
> Flex Conversations requires Flex UI 2.0.x. If you are on Flex UI 1.x.x, refer to the [Messaging in Flex](/docs/flex/developer/messaging) pages.

The **Interaction Channel Participant** subresource represents the actors communicating in an interaction channel. Typically, a channel will include people like agents, customers, and supervisors.

## Participant Properties
