Final answer:
Flow Designer actions are reusable operations that can be used in ServiceNow flows. They can be built-in actions or custom actions created by the user. They can be contained in a spoke and can be used in both linear and non-linear workflows.
Step-by-step explanation:
Flow Designer actions are a feature in the ServiceNow platform that allow you to perform specific operations in a flow. They provide a way to execute reusable operations across multiple flows, making your flows modular and efficient.
In addition to the built-in actions provided by ServiceNow, you can also create your own custom actions using Flow Designer. This gives you flexibility and the ability to tailor your flows to your specific needs.
Flow Designer actions can be contained within a spoke, which is a group of actions that can be collapsed or expanded within a flow. This helps to organize and manage complex flows by grouping related actions together.
Flow Designer actions are not only applicable to linear workflows. They can be used in both linear and non-linear workflows, allowing you to create flows with branching and conditional logic.
