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.

Class Library Reference

The Class Library Reference documentation is no longer available in this and future versions of K2 Five developer references, but you can still use the class library reference in the K2 Five (5.3) Developers Reference. Be aware that class libraries may be removed from future versions of K2 Five and may or may not be available in current K2 Five installations.

For code samples and more information on working with the available K2 APIs, please refer to the relevant API section of this documentation, such as the Runtime APIs .
