Table 1. Event Topic Options



Topic ID

Event topic identifier.


Name of the event topic.


Description of the event topic.


Name of the service for which this event topic is registered.


Indicates whether you can create a blocking subscription for this event topic.

Blocking subscriptions are used to change the event's payload or to synchonously run your custom logic when the results of a second workflow for the same event depend on the results of the first workflow.


Indicates whether an event topic subscription can publish a reply event to the service that originally produced the event. If the value is yes, a reply is sent to the service that published the original event when the workflow finishes. The reply contains the output of the vRealize Orchestrator workflow and any error details.


Describes the structure of the event's payload.

You can use the schema to create workflows that can use the payload information.
