What are Plugins
Before adding script to ServiceNow, administrators should check the list of available plugins
Plugins provide additional optional functionality within a ServiceNow instance
System Definition > Plugins
System administrators have control over when to activate plugins.
Some plugins include demo data - sample records that are designed to illustrate plugin features for common use cases. Loading demo data is a good policy when first installing the plugin on a development or test instance. Demo data can loaded after the plugin is activated by repeating this process and selecting the checkbox. If the plugin depends on other plugins, these plugins and their activation status are listed.
Most plugins are published, and system administrators can activate any published plugin. But, some plugins are available only by request due to operational considerations making the plugin only appropriate for certain deployments. In these cases, to activate the plugin, make a Service Catalog request to ServiceNow Technical Support using the Request Plugin Activation form at https://hi.service-now.com.
