ActiveVOS WSHT API

Process Server implements the operations described by the OASIS WS-HumanTask (WSHT) API task client specifications to manage human tasks as well as interact with specific tasks. In addition to WSHT API, the Process Server also provides an extension API to the OASIS WSHT API with enhanced functionality. This document introduces the reader to the Informatica implementation of the WSHT and Extension APIs, and includes a few examples describing the use of the API via SOAP and indirectly via Java code using JAX-WS. You should read the WS-HumanTask Architecture PDF document to get an appreciation of WSHT. This document will help you understand concepts necessary for using the API.

HumanTask Related Web Service Endpoints

The follow table shows the Human Task related web service endpoints. Note that these endpoints require that the client application provide login credentials of the principal.

Name	Service Endpoint	Description
WSHT API	http://host:port/active-bpel/services/AeB4PTaskClient-taskOperations Name	WSHT API as described by ws-humantask-api.wsdl.
Process Server Extensions to WSHT API	http://host:port/active-bpel/services/AeB4PTaskClient-aeTaskOperations	Additional operations for interacting with human tasks. Note the service name ends with "aeTaskOperations" - the "ae" prefix indicating an Informatica-specific service.
WSHT Task Feeds	http://host:port/active-bpel/services/REST/AeB4PTaskFeed	The WSHT API getMyTasks() operation represented as a RSS or ATOM syndication feed.
