By using a vRealize Orchestrator integration, or extensibility actions with Cloud Assembly, you can create subscriptions to extend your applications.

Extensibility subscriptions allow you to extend your applications by triggering workflows or actions at specific life-cycle events. You can also apply filters to your subscriptions to set boolean conditions for the specified event. For example, the event and workflow or action only triggers if the boolean expression is 'true'. This is helpful for scenarios where you want to control when events, actions, or workflows are triggered.
Tip: In the filter events in topic text box, use the "Alt + Space" keys on Windows or "Option + Space" keys on Mac to display filter options.



  1. Select Extensibility > Subscriptions.
  2. Click New Integration.
  3. Enter the details of your subscription.
  4. Select an Event Topic.
  5. (Optional) Set conditions for the event topic.
  6. (Optional) If applicable, configure the blocking behavior for the event topic.
  7. Click Runnable item and select vRO Workflow or ABX Action from the drop-down menu.
  8. Select a workflow or extensibility action that you want to run in your subscription.
  9. (Optional) To define the project scope of the extensibility subscription, disable Any Project, and click Add Projects.
  10. Click Create save your subscription.


Your subscription is created. When an event, categorized by the selected event topic, occurs the linked vRealize Orchestrator workflow or extensibility action is initiated and all subscribers are notified.

What to do next

After creating your subscription, you can create or deploy a blueprint to link and use the subscription. You can also verify the status of the workflow run in the Extensibility tab within Cloud Assembly. For subscriptions containing vRealize Orchestrator workflows, you can also monitor runs and workflow status from the vRealize Orchestrator client.
