Is it necessary to use the Exit subflow action at the end of each subflow?

Using the Exit subflow action at the end of each subflow is not necessary because subflows in Power Automate are designed to terminate automatically once the last action within them has been completed. When a subflow reaches its end, it returns control to the parent flow without requiring an explicit exit command.

This automatic behavior simplifies flow design and keeps the subflow logic clean, enabling developers to focus on implementing the intended functionality rather than managing flow control explicitly with exit actions. An exit action can be beneficial in cases where a subflow may have multiple exit points or when you want to clarify intent in the flow; however, it does not need to be included at the end of every subflow. This allows for flexibility in structuring the flow, preventing unnecessary clutter while ensuring that flows execute as planned.
