To consume this, we need WSDL.
The Web Services Description Language (WSDL) is an XML-based interface description language that is used for describing the functionality offered by a Web Service.

Once, WSDL is downloaded and saved on local drive. We have to go to Salesforce and navigate to “Setup | Develop | Apex Classes”. On right hand side, you will find button named as “Generate from WSDL”. This button will generate equivalent Apex class to support Webservice call. In some Programming languages, these classes are known as Proxy classes or Stubs.
When we click on “Generate from WSDL” button, it will prompt for WSDL File. Select WSDL file downloaded previously and click on “Parse WSDL” button. On next page you will get this error : “Failed to parse wsdl: Found more than one wsdl:portType. WSDL with multiple portType not supported”.
