  ShipHawk's event surface is HTTP webhooks, managed through the API itself. There is no
  AsyncAPI document, no streaming/SSE surface and no message broker — so no asyncapi/ spec
  is emitted, only this webhook catalog. The event list below is the one ShipHawk returns
  from its own discovery endpoint, GET /api/v4/webhooks/events.
asyncapi_spec: none published
transport: HTTP POST callback
subscription_model: >-
  Self-service through the API. A subscription is a Webhook object with a callback_url and an
  events[] array; a single subscription can carry many event types, and an account can hold
  many subscriptions.
discovery_endpoint:
  method: GET
  path: /api/v4/webhooks/events
  description: Returns the list of event types available to the account.

- name: shipment.documents_update
  resource: Shipment
  documented_payload_example: false
  note: >-
    Returned by GET /api/v4/webhooks/events and accepted in the events[] enum, but the
    reference publishes no example payload for it.
- name: shipment.create_from_order
  resource: Shipment
  documented_payload_example: true
  source_section: Shipment Create From Order Event
- name: shipment.create
  resource: Shipment
  documented_payload_example: false
  note: >-
    Listed in the events[] parameter enum on Create a Webhook but NOT returned by the
    documented example response of GET /api/v4/webhooks/events. The two lists in the
    reference disagree; trust the live discovery endpoint for the account.
- name: proposed_shipment.create
  resource: ProposedShipment
  documented_payload_example: false
  note: In the events[] enum only, as above.
- name: order.document_create
  resource: Order
  documented_payload_example: false
  note: In the events[] enum only, as above.
security:
  signature_verification: false
  signature_header: none published
  mechanism: >-
    Optional HTTP Basic authentication on the callback — the subscriber supplies
    use_basic_auth, basic_auth_username and basic_auth_password, and ShipHawk presents them
    to the callback URL. There is no HMAC signature, no timestamp header and no replay
    protection, so a receiver cannot cryptographically verify that a payload came from
    ShipHawk. Basic auth over TLS is the only authenticity control offered.
  ip_allowlist: not published
delivery:
  retry_policy: not documented
  ordering_guarantee: not documented
  at_least_once: not documented
  timeout: not documented
  dead_letter: not documented
  note: >-
    ShipHawk publishes no delivery semantics for webhooks at all. Receivers should assume
    duplicates and out-of-order arrival are possible and reconcile against the REST resource
    (GET /api/v4/shipments/:id) rather than trusting the event body as the system of record.
gaps:
- No AsyncAPI document.
- No signed payloads (HMAC) — only optional Basic auth.
- No published retry/backoff, ordering or delivery guarantees.
- Example payloads published for only 5 of the 10 event names that appear in the reference.
- The events[] enum and the discovery-endpoint example response list different sets of events.
