Send Message

Send Message writes an arbitrary response message to the chat conversation.

Was es tut

Respond to the user with any message — useful for fixed replies, routing notifications, and emitting node outputs to the chat.

Hinweis:

Send Message can only reply within an exchange that a user has initiated, which means the user must send a message first before the Flow can respond to the chat. Flow-initiated exchanges — sending a message without a prior user turn — are not yet supported.

Eingaben

Feld	Beschreibung
Konversations-ID	The ID of the conversation to write to. Bind to the conversation trigger's output, for example $vars.conversationTrigger1.output.conversationId.
Exchange ID	The exchange (back-and-forth turn) to append this message to. Bind to a Wait for Message node's latest exchange, for example $vars.waitForMessage1.output.conversationContext.latestExchangeId.
Inhalt	The message content. Supports expressions to inject variable data.

Fixed messages

Send a static acknowledgment before a long-running node:

Hold on a moment while we process your request...

Announce routing to a specialist conversational agent before the Wait for Message that starts the specialist agent's loop:

You have been routed to the specialist agent. How can we help you today? 

Expressions with variables

Use variables to emit the output of an upstream node using an expression:

`The result is ${$vars.previousNode.output.result}.`
