WSDL stands for Web Service Description Language. It is an XML file that describes the technical details of how to implement a web service, more specifically the URI, port, method names, arguments, and data types. Since WSDL is XML, it is both human-readable and machine-consumable, which aids in the ability to call and bind to services dynamically. Using this WSDL file we can understand things like
- Port / Endpoint – URL of the web service
- Input message format
- Output message format
- Security protocol that needs to be followed
- Which protocol the web service uses
WSDL describes web services in an xml format so that different technologies can understand
