About Using Web Services

When creating, implementing, and publishing Web services, implement the WS-Security UserName Token mechanism to pass user credentials (Username and Password) to Web services. Passing the user name and password in the Web service URL is not supported in Siebel CRM version 8.1 or 8.2.

Using the WS-Security UserName Token mechanism means that user names and passwords do not have to be passed to Web services in the URL and a session cookie does not have to be passed with the HTTP request. For additional information on the WS-Security UserName Token, see Integration Platform Technologies: Siebel Enterprise Application Integration.
