Start nodes serve as the entry points for workflows and chatflows. There are two types of Start nodes, each initiating your application in a different way.
  • User Input: The application is initiated by direct user interaction or API calls.
  • Trigger (for workflows only): The application runs automatically on a schedule or in response to a specific third-party event.
Only applications that start with a User Input node can be published as standalone web apps or MCP servers, exposed through backend service APIs, or used as tools in other Dify applications.
A single workflow can have both User Input nodes and triggers as parallel start points.
