Web Services Description Language (WSDL) is an XML format defined by the World Wide Web Consortium (W3C). Each WSDL file describes network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.
A WSDL file describes a SOAP service. It includes XML schema information that describes the input parameter values that need to be sent in a SOAP request message, and the output parameter values that can be extracted from a SOAP response message. It also specifies the delivery method (usually HTTP) and the URL of the Pega servlet that processes the SOAP requests.
A WSDL file is generated as part of Pega SOAP services deployment and is available in the Deployment Results section on the service package for SOAP service types.
