The WSDL is an XML document that describes the protocols and formats used by a web service.

The WSDL contains a description of the data to be passed to the web service so that both the sender and the receiver of the service request understand the data being exchanged. The WSDL elements also contain a description of the operations to be performed on that data, so that the receiver of a message knows how to process it, and a binding to a protocol or transport, so that the sender knows how to send it.

You can view and download the WSDL files for the web services hosted by the PowerCenter Web Services Provider on the Web Services Hub Console.
