Sitecore Commerce plugins
A plugin is an independently-publishable extension to the Sitecore Commerce Commerce Engine. Plugins are published as lightweight NuGet packages to either the public repository or a secure private one.
Plugins can contribute:
Models
Components
Entities
Pipelines
Events
Commands
Lists
Plugins can take a dependency on another plugin, in order to extend the functionality.
Customers can create their own plugins to support new scenarios. Partners can create plugins to use as value-added IP in commerce engagements.
