Which type of flow allows for user input during execution?

The type of flow that allows for user input during execution is the Screen flow. This flow type is designed specifically to interact with users, enabling them to enter data, make selections, or navigate through a series of screens during the flow's runtime. Screen flows can incorporate various components such as input fields, picklists, and buttons, making it possible for users to provide real-time feedback and data which can then be processed further within the flow.

In contrast, other flow types such as autolaunched flows are designed to run in the background without user intervention, executing predefined logic without any screens or user inputs. Scheduled flows, as the name implies, run on a defined schedule but also do not allow for real-time user input. Record-triggered flows are initiated by changes to records and function automatically based on defined criteria, lacking the interactive elements that Screen flows provide. This interaction capability is what distinguishes Screen flows and makes them particularly effective for scenarios requiring user participation.
