The canvas
The canvas is where a workflow takes shape. It has three parts: the node palette, the canvas itself, and the settings panel.
Adding nodes
Drag a node from the palette onto the canvas. Every workflow needs exactly one Start node and at least one End node; add whatever other nodes you need in between.
Connecting nodes
Drag from a node's output handle to the next node's input handle to create a connection. The data a node produces becomes the input of the node you connect it to. For the full rules, see the Nodes overview.
Configuring a node
Click a node to open its settings panel. Each node type has its own parameters — look up any node in the Nodes section to see exactly what it expects and an example.
Testing as you build
You don't have to finish a workflow to try it. Use Test Run at any point to execute what you have with sample data and watch each node light up. See Test runs.
Build in small steps and test often. Add a node or two, run, confirm the data looks right, then continue. It's much faster than building the whole flow and debugging it all at once.
