We're updating some of our product names. K2 Five is now Nintex Automation. You may see both product names in our help pages while we make this change.

Runtime APIs and Services

This section covers the available APIs used to interact with K2 components at runtime.

Workflow	Describes the available Services and Assemblies that can be used to interact with and manage Workflows at runtime
SmartObjects	Describes the available Services and Assemblies that can be used to interact with and manage SmartObjects at runtime
K2 Server	Describes assemblies and services used to interact with a K2 Server.

K2 client API .DLLs that you reference (such as HostClientApi.dll, SmartObject.Client.dll and the Workflow client API), are thread safe.
If you open a connection with the API, you should close and dispose of the connection object.
