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.

How it works

1. Add the Chat Trigger node to your agent.
2. Set Make Chat Publicly Available = true and Mode = Embedded Chat.
3. Connect the trigger to an Agent or Chain LLM node downstream.
4. (Optional) Connect a Simple Memory node to remember conversation history per session.
5. 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 Workflow 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 Workflow 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 Embed that link in your own UI only — do not publish it as a buyer-facing surface.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.
