Product Advertising API supports the SOAP message protocol for calling Product Advertising API operations over an HTTP connection. The easiest way to use the
SOAP interface with your application is to use a SOAP toolkit appropriate for your
platform. SOAP toolkits are available for most popular programming languages and
platforms.
The service's Web Services Definition Language (WSDL) file describes the
operations and the format and data types of their requests and responses. Your SOAP
toolkit interprets the WSDL file to provide your application access to the operations.
For most toolkits, your application calls a service operation using routines and classes
provided or generated by the toolkit.
