URL for accessing KFS 4.x Web Services


QAID # 18355 Published 

Question / Problem:

When attempting to access the list of Kofax Front Office Server (KFS) 4.x Web Services using the URL that is documented in the KFS 4.0 Web Services Connector Reference, the request is redirected to the KFS 4.0 Thin Client login screen. What is the correct URL to access information regarding the KFS 4.x Web Services?

Answer / Solution:

As a security precaution, KFS 4.x will automatically redirect any unrecognized URL that begins with http://<Server>/KFS/ to the Thin Client login page. The Web Services list that was present in KFS 3.x has been replaced in KFS 4.x with a WSDL (Web Services Description Language) file for each Web Service. Unfortunately, the KFS 4.0 Web Services Reference still references the old KFS 3.x Web Services List URL.

This issue has been documented in SPR 113652.

To view the WSDL of a Web Service, use a URL in the following format:


For <Web_Service_Name>, use only the name of the service itself. For example, if the namespace is Kofax.KFS.Services.Contracts.Legacy.WebServices.DocTracking, the service name is "DocTracking". The word "Service" is appended directly to the end of the service name so that the name appears as "DocTrackingService" in the URL. The following example URL would be used to access the WSDL for the DocTracking service on the server "KFS1".



Note: An exception applies to the Metrics service, which uses the following URL format:


This information is also documented in the KFS 4.0.1 Release Notes.
