Nintex Xtensions™
Software Development Kit

Nintex Xtensions is Nintex's extensibility framework that allows you to define your own custom connectors for use in the Nintex Workflow Platform. This SDK guides you through the process of defining a custom connector, and importing and configuring it in the Xtensions portal, in preparation for use in workflow designs.

NOTE: Currently, the framework only supports the design of custom actions. Custom workflow start events will be available soon.
