# Messages

> Represents a message sent by an Internal User or Client in the Messages App of your portal, inside a Message Channel.

This resource represents a message. A message is sent by an Internal User or Client in the Messages App of your portal. Every message is sent inside of a [Message Channel](/docs/api-reference/resources/message-channels). This API resource describes the metadata of the message object.

The Messages App supports basic markdown-style formatting. Review the table below to see what exactly is supported.

Note that we don't yet support sending or retrieving files attached to messages.
