The Rules module allows site administrators to define conditionally executed actions based on occurring events (known as reactive or ECA rules).
- Build flexible content publishing workflows changes
 - Send customized mails to notify your users about important
 - Create custom redirections, system messages, breadcrumbs, ...
 - Build an eCommerce store using Ubercart
 
And many more...
- Obviously, you may use reaction rules to react upon any event with custom conditions and actions.
 - Allows functionality to be re-used via components.
 - Flexible scheduling system that allows scheduling any component / action.
 - Users can share their customizations by using the built-in import/export feature.
 - Modular input evaluation system.
 - The module has been developed with site performance in mind, so it makes use of caching routines to speed up rule evaluation.
 - Rules 2.x features improved APIs, a new admin UI, support for all entity types, parameter configuration via simple data selection (i.e. just pass node:author as argument) and much more.
 
Install Entity Plus, Entity UI, and Entity Tokens and this module using the official Backdrop CMS instructions.
If you will be upgrading a site from Drupal 7, you should install stub modules in your D7 installation before starting the upgrade process.
Rules has four component modules, each with separate activation:
- Rules
 - Rules Scheduler
 - Rules UI
 - Rules translation - for internationalization
 
Then visit the configuration page at Administration > Configuration > Category > Rules (admin/config/category/rules) and enter the required information.
