In Salesforce Flow, which type of variable can store data that users input during the flow execution?

In Salesforce Flow, the Input variable is specifically designed to capture data that users provide during the execution of the flow. These variables allow the flow to accept information from users, making it possible to customize behavior based on user input. When flows are initiated and then run, Input variables enable developers to pass values into the flow, which becomes essential for scenarios where user decisions or data entry dictate the path the flow will take.

The other types of variables serve different purposes: Text variables store single strings of text, Collection variables hold multiple items of the same type (like a list of records), and Global variables are system defined variables that provide built-in values like current user context. While all these variable types play important roles in flow execution, they do not specifically capture user input in the same manner that Input variables do.
