Is it possible to create a flow without any triggers?

A flow in ServiceNow Flow Designer requires a trigger to initiate the execution of the flow. Triggers are essential components that start the flow based on specific events or conditions. They establish the context for when the flow will run, such as a record being created, updated, or deleted or when an incoming webhook is received.

The idea that a flow can exist without any triggers is incorrect because the fundamental design of Flow Designer is built around event-driven automation. Without a trigger, there would be no mechanism to launch the flow, and as a result, it wouldn't function as intended.

While subflows can indeed be called from other flows or even through a trigger, they themselves still need to be initiated by another flow or event. Hence, the aim of having a trigger is crucial for the operational integrity of flows within ServiceNow Flow Designer. This ensures that flows align with automated processes, maintaining efficiency and organization within workflows.
