Basic Parameters

Parameter	Description
Channel	Channel, private group, or IM channel to send message to. Can be an encoded ID, or a name.
Content	The text to send. Whether the parameter is required depends on your usage of the Blocks & Attachments parameters. For more information see Slack documentation.
User	The ID of the user who will receive the ephemeral message. The user should be in the channel specified by the channel parameter.

Advanced Parameters

Parameter	Description
Attachments	A JSON-based array of structured attachments, presented as a URL-encoded string.
Blocks	A JSON-based array of structured blocks, presented as a URL-encoded string.
Parse	Change how messages are treated. Defaults to none. For more information see Slack documentation for more detail.
Thread Timestamp	Provide another message's Timestamp value to post this message in a thread. You can obtain a message's Timestamp by using the Get Channel Message's action.
