You create workflow subscriptions that use the event broker service to monitor the registered services for event messages in vRealize Automation, and then run a specified vRealize Orchestrator workflow when the conditions in the subscription are met. To configure the subscription you specify the event topic, the triggering conditions, and the workflow that runs when triggered.

Tenant administrators can create and manage the workflow subscriptions that are specific to their tenant.

The system administrator can create and manage system workflow subscriptions. The created system workflow subscriptions are active for events in any tenant and for system events.
