How does WSDL works?

WSDL (Web Services Description Language) is an XML-based language used to describe the functionalities of a web service. It defines the service's endpoints, the operations it can perform, the parameters required, and the format of the data exchanged. Clients use the WSDL file to understand how to interact with the service, including the methods available and the expected input and output formats. By automating the generation of client-side code, WSDL simplifies the integration of web services into applications.
