Start

The Start node indicates the start of a Flow.

Variables

These variables will be set when you trigger the current Flow from another Flow using the (Flow Component) or (Flow Starter) node.

The variables allow you to have context like the Start / Trigger Object and Start / User variables.

If you make the variable required you will have to set it in the Flow Component or Flow Starter node.

Run ID

The Start node exposes a built-in string variable runId that holds the unique identifier of the current flow run. This variable is available from the very first step and can be passed to other nodes — for example to include the run ID in an email, store it on a business object, or use it as a correlation key when calling external systems.
