When you run a session with PowerExchange for Web Services, the PowerCenter Integration Service communicates with the web service provider application or web server. This is the server that hosts the web service that you want to use in a PowerCenter session. The application or web server contains a web services host. The web services host contains a WSDL file and the web services that the WSDL file describes.

To communicate with a web services host, the PowerCenter Integration Service requires an endpoint URL. The PowerCenter Integration Service uses the endpoint URL defined in the Web Service application connection or contained in the WSDL file as the location attribute. You can configure a Web Service application connection in the Workflow Manager. You can also configure a web service source, target, or transformation to use a dynamic endpoint URL.
