Web Service Connector WSDL Reference (v12.2.18)
To implement an Intelligent Advisor web service connector, at a minimum a metadata service must be provided. To allow interviews to load data from and save data to your connected application, the data service interface must also be implemented. Developers using the Determinations API may also find it useful for you to implement the data service, as the Answer service and the Interview service are designed to be used in conjunction with the Load and Save actions.
