Chat Trigger
Start a workflow from a chat deployment
Overview
The Chat trigger creates a conversational interface for your workflow. Deploy your workflow as a chat and users can interact with it through a shareable URL. Each message starts a new workflow execution using your latest deployment.
Runtime Outputs
The trigger writes three fields that downstream blocks can reference:
| Reference | Description |
|---|---|
<chat.input> | Latest user message |
<chat.conversationId> | Conversation thread ID |
<chat.files> | Optional uploaded files |
Files include name, mimeType, and a signed download url.
Usage Notes
- Add one Chat Trigger block per workflow.
- Deploy the workflow in chat mode.
- Share the deployment link—every reply reuses the conversation ID so the workflow can keep context.
The builder blocks multiple Chat Trigger blocks in the same workflow.
