The Windchill RV&S Application Programming Interface (API) offers a direct way for custom applications to interact with workflow and document management, and configuration management. The Windchill RV&S API can be used in triggers in a manner similar to the CLI; however, the API allows direct access to input and output without parsing.

Using the Windchill RV&S API in triggers is useful for performing CLI operations that are not covered by a Bean (like running a report), and running configuration management CLI commands from workflow and document events, and workflow and document commands from configuration management events.
