What type of variables can be included in Client Actions?

In Client Actions within OutSystems, you can utilize both Input and Output Parameters. Input Parameters are used to provide data to the Client Action from its caller, allowing the action to receive necessary information to perform its logic. Output Parameters serve to return data back to the caller after the Client Action has completed its execution, enabling the sharing of results or status updates.

The ability to define these parameters allows for greater flexibility and modular design in the application. By utilizing Input Parameters, developers maintain clear and well-defined interfaces for actions, while Output Parameters facilitate interaction between different parts of the application, helping ensure a cohesive user experience.

Local Variables, while helpful within Client Actions for temporary storage or intermediate calculations, are not included in the definition of variables that can be passed in or out of the action. Therefore, they do not influence the parameter types available for Client Actions. This focus on managing just Input and Output Parameters simplifies how the actions interact with other elements in the application.
