Signal Node
Estimated Reading Time: 5 minutes
Overview
As you progress through your workflow, a Signal node represents a swimlane change. The current user gets an alert that they can't take any more actions at this point. So, another role/user must take over the next steps in their workflow swimlane.
You can add any number of Signal nodes to your workflow. The node includes a single input port for connection to one or many other nodes. The Signal node also offers an output port for connection to the next node.
You'll find the Signal node in the list of nodes to the left of the Workflow Builder.
