When are input and output variables defined in Power Automate?

In Power Automate, input and output variables play significant roles in defining how data is passed into and out of flows, particularly when working with robotic process automation (RPA) capabilities.

Input variables are essential for providing the initial data that a flow requires to execute. These variables are defined at the beginning of the flow or the configuration stage, ensuring that all necessary information is available before the flow operates. This setup enables the flow to utilize these inputs effectively throughout its execution.

On the other hand, output variables are defined during the flow execution. These variables are used to store results or data generated by the flow after it has processed the input variables. Defining output variables at this stage allows for the dynamic collection of data that the flow generates, such as results from actions taken or data retrieved from external systems.

Thus, this approach allows for a clear distinction in the timing and purpose of input and output variables, with input variables needing to be established in advance to set the flow in motion, while output variables are created and utilized as the flow executes its tasks.
