The workflow_deleted event is sent when a workflow that contains a step powered by your app is deleted.

The workflow_draft_configuration field in the event payload shows the workflow's current draft state, including its steps.

Subscribe to the workflow_step_deleted event as well to know, instead, when a workflow has removed a step powered by your app from the workflow itself.
