Flash authoring panels
The Web Services panel
You can view a list of web services, refresh web services, and add or remove web services in the Web Services panel (Window > Other Panels > Web Services). When you add a web service to the Web Services panel, the web service is then available to any application you create.
You can use the Web Services panel to refresh all your web services at once by clicking the Refresh Web Services button. If you are not using the Stage but instead are writing ActionScript code for the connectivity layer of your application, you can use the Web Services panel to manage your web services.
Web Services sounds like a another strange thing but they are really complex technology. Complicated to understand at the very beginning, but simple and easy to use at the very end of You learning tour. Be patient to discover full potential of Web Services.
