Start Node
By default, every Playbook has a start node added to the Playbook canvas. The start node represents the start of a Playbook workflow. You must retain the start node and then add other nodes to the Playbook workflow. If an event is configured for a Playbook or if the Playbook execution is triggered based on the event, then the data of a triggered event is stored in the start node. You can use dynamic path expressions to retrieve this data and utilize it in other nodes of the Playbook workflow. For more information on retrieving event data using dynamic path expressions, see Fetch Event Data.
