We have a process that downloads geometry from a feature service, and would like to be notified when the service is modified so that we can pull down the new geometry
We've wondered about this as well. We were thinking about using WebHooks to trigger push notifications to our apps, but only if we can easily monitor feature service changes to trigger the hooks.
You can use Server object interceptors to trigger your webhooks
