Endpoint providers can instruct Acoustic Exchange to alert them when Acoustic Exchange users add or modify subscriptions for events that an endpoint provides or receives. You make such an instruction as an API call to Acoustic Exchange.
For example, Acoustic Exchange can notify you when users add a new event subscription to an endpoint. Acoustic Exchange can also send a notification when a user disables all event subscriptions for the endpoint.
Monitoring event subscription changes can help you to manage system resources because you need to send event notifications to Acoustic Exchange only for events that are actually requested by Acoustic Exchange users. Subscription monitoring has the additional benefit of indicating which events are the most or least popular among Acoustic Exchange users.
