DocuSign
K2 integrates with DocuSign through the DocuSign feature, which enables SmartObjects and Workflow wizards that enable various operations in DocuSign. For more information on how to activate the DocuSign feature, please see the DocuSign Feature Activation topic in the User Guide.
There are no specific installation steps required to install this Service Broker, it is included and available by default in a K2 environment.
You do, however, need to use the Feature Activation tool in the K2 Management Site to enable integration with DocuSign.
