Workflow Service

The Workflow Service Service Type exposes runtime operations for adding comments and attachments to a workflow. Additionally, the service exposes runtime operations to work with K2 workflows, such as starting workflows, opening and completing tasks, and operations for adding comments and attachments to a workflow. A service instance of this service type is registered automatically when you install K2. You do not need to register another instance.

Service Authentication

The following Authentication Modes may be used with the Service Type:

Impersonate
ServiceAccount
Single Single-on
Static

Service Objects

During installation of K2, the Workflow Service Service Instance creates Service Objects in the Workflow Service category, which are used by K2 to manage comments and attachments to workflow instances. The screen shot below shows the available methods of these Service Objects.

In addition, if workflows are deployed with the Create Workflow SmartObjects option selected, the service will create Service Objects for the selected items in the configuration of the Create Workflow SmartObjects screen, as specified by the workflow designer.

SmartObjects

K2 automatically generates SmartObjects for these Service Objects. SmartObjects can be automatically created by selecting the Generate SmartObjects for this Service Instance check box when creating a new Service Instance. Designers can use the SmartObject design tools to build advanced SmartObjects that leverage the Service Objects in this service. It is recommended to use the SmartObject design tools to create SmartObjects rather than generating SmartObjects, since this allows better control over the naming, behavior and design of the SmartObject and its methods and properties.

Considerations

The Create Workflow SmartObjects property must be set to True on the process properties to create workflow-specific SmartObjects when the process is deployed.
You may want to limit the number of processes that generate Workflow SmartObjects since it can increase the amount of time taken to deploy the workflow definition.
