Web of Science™ Web Services are authenticated Web services. They require successful validation of your authentication credentials prior to data retrieval.
Web of Science Web Services authenticates access by username and password. Your credentials should already be set. If you need to verify your credentials, or if you want to change them, contact Thomson Reuters Technical Support at http://science.thomsonreuters.com/support/.
The initial request sent to the WOKMWSAuthenticate service by your web services client submits your credentials to the service. If your credentials are validated, a session identifier is returned in the service response. Otherwise, a SOAP fault is returned.
All subsequent requests to Web of Science Web Services do not require authentication as long as the session ID has not expired and is included in each service request.
