Stop

A terminal node: when reached, it ends the current branch. Use it to short-circuit a workflow once a decision has been made, or to deliberately fail a run so an upstream Try / Catch can react.

When to use

• After an If / Else, to stop a branch early — e.g. "if the amount is below the threshold, stop; otherwise continue processing."
• To fail the run on purpose when a business rule is violated, with a message that a surrounding Try / Catch (or the run history) will show.

Configuration

Field	Required	What it does
mode	No	end (default) — stop this branch cleanly, no error. error — fail the run.
message	No	Shown when mode = error. The failure reason, visible in run history and catchable by an upstream Try / Catch.

What it outputs

Nothing — it's a leaf. In end mode the branch simply finishes; in error mode the run is marked failed with your message.

Gotchas

• Stop ends only the branch that reaches it. Other parallel branches keep running. It is not a global "abort everything" switch.
• error mode fails the run unless the failure is caught by a Try / Catch upstream — use it deliberately.
• Stop is free — it never counts against your usage.
