The CBSV Web Service is designed to support interoperable machine-to-machine interaction over the Internet. This provides instantaneous response and handles volumes easily. With the Web Service, companies create their own, unique interface with CBSV. If you are a developer who works for a company that plans to access CBSV through a Web Service, it is recommended that you refer to these CBSV Web Service Documents.

The Web Service Description Language (WSDL) for CBSV is documented in the Interface Specification for CBSV Web Service document. The Web Services Description Language is an XML-based language that provides a model for describing Web services. WSDL is often used in combination with SOAP and XML Schema to provide Web services over the Internet. A client program connecting to a Web service can read the WSDL to determine the functions that are available on the server.

If you plan to use a Web Service to connect to CBSV the following documents provide the necessary specifications.
