asyncapi_note: 'Cisco publishes no AsyncAPI document for Catalyst SD-WAN. There is still a real event
  surface, captured here as a webhook catalog: outbound alarm webhooks configured through the REST API,
  plus one server-sent-events stream.'
webhooks:
  style: provider-configured outbound HTTP callback, registered through the API
  registration:

  auth_to_receiver: HTTP basic (webhookUsername / webhookPassword) set on the rule
  severities:
  - Critical
  - Major

  event_selector: alarmName — one rule per alarm type (e.g. BFD_Node_Up); the alarm catalog is enumerated
    by the /alarms/* operations
  delivery_semantics:
    retries: undocumented
    signing: none — no HMAC signature header is documented
    ordering: undocumented
    replay: undocumented
  gaps:
  - no signature/verification mechanism
  - no delivery retry or dead-letter policy published
  - no schema for the delivered alarm payload in the contract
streams:
- name: authentication events
  method: GET
  path: /admin/events/{sseSessionId}
  operationId: listenAuthEvents
  protocol: server-sent events
  media_type: text/event-stream

  note: The only text/event-stream response in all 4,138 operations.
polling_alternatives:
- name: alarms
  paths:
  - /alarms
  - /alarms/aggregation
  - /alarms/count
  - /alarms/doccount
  - /alarms/severity/summary
  note: 37 alarm operations; the normal integration pattern is polling or query, not push.
