Flow Designer
Flow Designer is ServiceNow's low-code automation builder where a trigger plus a sequence of reusable actions replaces the legacy Workflow Editor.
Also searched as: flow, subflow, flow vs workflow.
In practice
Flows are triggered by record changes, schedules, inbound REST or catalog items. Actions are reusable steps, subflows encapsulate logic with inputs and outputs, and spokes add ready-made integration actions through IntegrationHub. Flows are scoped, versioned and testable, which is why new automation belongs here.
Example
A catalog-item flow that creates an approval, waits for it, then calls a Jira spoke action to raise a ticket.
What interviewers check
You should be able to say when to keep a legacy Workflow (no changes needed) versus rewrite it as a Flow.
