It said any third-party applications that have subscribed to alert notifications using the Orion SDK.But how do I find the sharing data?
That knowledge base article is misleading. The interface used by Alert Central is not intended for use by customers or third-party applications. I'll get the article updated.
Customers can query for alert status using the Orion.AlertStatus entity. If you need real-time integration with alerts, the best option is to configure a trigger action to run a script.
