Output

Define workflow outputs and termination points

The Output node was previously called End. It’s now optional in a workflow and used only to explicitly output data to the end user.

End nodes are only for Workflow applications. Chatflows use the Answer node instead to deliver responses during the conversation flow.

Output Configuration

In an Output node, you can define what data from your workflow should be returned to users by adding output variables, such as an LLM’s response. At least one output variable must be specified; otherwise, nothing will be returned.

When exposed as a backend service API, workflows without an Output node will not return any values to API callers.
