The Extended APIs plugin provides an additional layer to Jive’s Core APIs. It includes web services used internally by products that can add functionality to your Jive Community. This plugin does not expose APIs for developers: it’s only accessible to products developed by Jive.
The Extended APIs plugin is required for Jive products that depend on these APIs. If you need to install it as part of a product installation, you’ll see the requirement clearly mentioned in the installation documentation.
