summary: >-
  Syniverse's event surface is Event Manager, exposed as the Event Subscription
  Service (ESS) API. It is a subscribe-then-deliver model rather than a per-resource
  webhook registration: a customer subscribes an application to a topic, creates a
  delivery configuration describing where and how events should land, and Syniverse
  pushes matching events to that endpoint over REST — either near real time or
  aggregated on a cron schedule into JSON files. Delivery attempts are themselves
  queryable resources, which is unusually observable for a CPaaS webhook layer. No
  AsyncAPI document is published; the API is documented as a rendered RAML console
  with no machine-readable definition available for download, so this artifact
  captures the event catalog rather than a harvested spec.

    The ESS API is the one Syniverse Developer Community product with no downloadable
    definition. Eleven other services publish OpenAPI or Swagger; this one is a
    rendered RAML console only. Nothing was fabricated to fill the gap.
