What are 'output parameters' used for in OutSystems actions?

Output parameters in OutSystems actions serve the specific function of returning values after the execution of the action. When an action is called, it may perform operations, computations, or data manipulations that generate results. These results can then be made available for use in the calling logic or other actions by defining appropriate output parameters. This mechanism essentially allows for the flow of data from the action back to the part of the app that called it, enabling developers to create dynamic and interactive applications based on the outcomes of various operations.

Each output parameter can hold a different type of returned value, whether it is a simple data type, an object, or a list. This enhances the reusability and modularity of actions within OutSystems applications. Understanding this function is crucial for effectively leveraging actions within OutSystems to manage data and application logic efficiently.

While input parameters provide the necessary information to an action upon its invocation, and conditions control the flow of execution, output parameters specifically focus on delivering results from the action back to the workflow or user interface. Storing error logs pertains to a different aspect of error handling and logging practices within the application, further delineating the purpose of output parameters.
