What tool can generate code for communication with a SOAP web service from a WSDL document?

WSDL2Apex is a tool specifically designed for generating Apex code that facilitates communication with SOAP web services given a WSDL (Web Services Description Language) document. When provided with a WSDL file, WSDL2Apex analyzes the service definition and automatically generates the necessary Apex classes and methods to enable seamless integration with the specified SOAP service. This includes the creation of both request and response classes that correspond to the operations defined in the WSDL, ensuring that developers can easily interact with the web service without having to write all the code manually.

The relevance and effectiveness of WSDL2Apex make it a valuable asset for any Salesforce developer needing to work with external SOAP web services, as it streamlines the process of handling web service communication and reduces the likelihood of errors that may arise from coding the integration from scratch.
