Hi JCDETOUR

I believe when referring to KB that you have found touching only on matters to do with ‘retrieve KB to start and get the worklist’ you mean the article from this link; https://help.k2.com/kb001941 corresponding to the tutorial found in this link here; https://help.k2.com/onlinetraining/tutorials/default.htm#Resources/Projects/WorkflowRuntimeAPI/WorkflowClientAPI.htm

I also do not have a straight up answer to your question, but I would recommend you take a look to the following information of a related matter as an KB article from the following URL; https://help.k2.com/kb000183 and see if it can help regarding your matter.
