How do you activate a flow after creating or editing it?

The process of activating a flow after creating or editing it in ServiceNow Flow Designer is accomplished by using the "Activate" button within the Flow Designer interface. Activating a flow is a crucial step because it makes the flow operational, enabling it to execute automatically based on the defined triggers and conditions.

While saving a flow in draft mode allows you to keep your work without making it live, it does not activate the flow for execution. Publishing the flow to a service catalog is not necessary for activation; this action is more about making the flow accessible to users rather than executing it. Sharing the flow with other users might enable collaboration or visibility but does not impact the activation status of the flow itself. Thus, using the "Activate" button is the correct method to ensure that a flow is ready and able to run in the intended scenarios.
