The workflow subscription is active and will trigger your snapshot workflow when an event message
indicates that a requested virtual machine is provisioned and activated.
What to do next
To test the workflow subscription, request a virtual machine in the service catalog. After the request
indicates successful provisioning, verify that the snapshot was created.
Working with Approval Workflow Subscriptions
You create pre-approval and post-approval workflow subscriptions so that you can send an approval
request to an external system for processing. The response, approved or rejected, is then processed by
vRealize Automation.
Approval Service Integration
You create a pre-approval or post-approval workflow subscription that runs a custom
vRealize Orchestrator workflow that processes the approval request in a system outside of
vRealize Automation.
In an approval policy approval level, you can select Use event subscription as the approver. This level
can be one of several in an approval policy. When a service catalog user requests an item to which an
approval policy is applied that includes the Use event subscription approver, the approval service sends
a message to the event broker service with the following results.
n
If you have a published workflow subscription with matching criteria, vRealize Orchestrator runs your
approve or reject workflow.
n
If you have a published workflow subscription, but the criteria do not match, you unpublished the
workflow subscription, or you do not have a published subscription, the approval level is approved
and the approval process goes to the next approval level.
The approval workflow subscription receives messages from the approval service and compares the
messages to the configured criteria for approval subscriptions. When it finds a message that matches the
criteria, the selected vRealize Orchestrator workflow starts to run. The published event data is passed to
the workflow as input and processed in the method specified in the workflow. The results of the workflow
are returned to vRealize Automation and the request is processed. If approved, the next approval level is
evaluated. If rejected, the request is rejected. If the approval service does not receive a reply within 24
hours, the default timeout for the approval service, the request is processed as rejected.
