Overview
The flow's two required ends and the automatic node that opens a loop.
Every Workflow starts at an Input node and ends at one or more Output nodes. Together they define the flow's interface: what the person fills in and what they get back.
A flow without an Output node runs to completion and delivers nothing.
What each node does
- Input: declares the variables the flow receives. Each one becomes a field in the run form.
- Output: declares the structure of the result returned to the person who ran it or to the system that called it through the API.
- Iteration start: appears on its own inside an Iteration node and represents the current item of the loop.
How data flows through
Input variables are available to every following node, in the {{ entrada.variable_name }} format.
Anything that doesn't go through the Output node is still recorded in the run, but doesn't show up as a result.
