Chat Trigger

The Chat Trigger node starts an agent run whenever a chat message is posted to your agent's chat link. It is ideal for building conversational agents that respond to messages from a chat client you embed in your own app.

indie.money compatibility

Feature	Status
POST chat messages (embedded mode)	Supported
Memory connection (Simple Memory)	Supported
`loadPreviousSession` action	Supported
Streaming responses	Partial — `responseMode=streaming` returns NDJSON after execution completes (synthesized chunks, not real-time per-token streaming). Connect a Chat Trigger to a Chain LLM or Agent node and the response stream contains one JSON event per output item.
Hosted chat web page (GET URL serves HTML)	Not supported — agents return 404 on GET. Embed your own chat client instead
`Basic Auth` authentication mode	Not supported — choose `None` and put your own auth in front of the agent link
`n8n User Auth` authentication mode	Not supported
File uploads in chat	Not supported

How it works

Add the Chat Trigger node to your agent.
Set Make Chat Publicly Available = true and Mode = Embedded Chat.
Connect the trigger to an Agent or Chain LLM node downstream.
(Optional) Connect a Simple Memory node to remember conversation history per session.
Publish your agent. Your agent's chat link accepts POST requests with this body:

{  "chatInput": "Hello, how are you?",  "sessionId": "my-session-123"}

The agent responds with the output of the last node (or with chunks if streaming is enabled).

Who pays

When caller-paid runs are enabled for the chat trigger, it follows the same two-link model as the Webhook node: a You pay link (runs draw on your agent balance) and a Caller pays link (unpaid calls get a price back; callers with a wallet pay per run). See Webhook Node (Trigger) for the full explanation.

When only owner-funded chat is configured, chat messages draw on your agent balance. Embed that link in your own UI only — do not publish it as a buyer-facing surface.

Loading previous session messages

When Load Previous Session is set to From Memory and a Simple Memory node is connected, sending the special body {"action":"loadPreviousSession","sessionId":"..."} returns the prior messages for that session, without invoking the agent.

Differences from n8n

n8n offers a built-in chat web page that opens automatically when you visit the trigger link in a browser. indie.money does not host that page. To build a UI, embed any standard chat widget in your own webpage and point it at your agent's chat link.
