Messages are how we communicate in a room. In Webex, each message is displayed on its own line along with a timestamp and sender information. Use this API to list, create, update, and delete messages.

Message can contain plain text, rich text, and a file attachment.

Just like in the Webex app, you must be a member of the room in order to target it with this API.
