In OutSystems, the HttpHelper component is often used to handle HTTP requests, especially when you need to call external APIs or services. It helps you make HTTP requests like GET, POST, PUT, DELETE, and manage responses in your OutSystems server actions.

However, when you're working with HTTP actions in server actions, or when you need to set specific HTTP status codes for server actions, you might want to handle it manually in your logic to return the right HTTP status, like 200, 400, 404, etc., based on different conditions.
