asyncapi_published: false
asyncapi_note: >-
  No AsyncAPI document is published. Probed https://signsealship.com/asyncapi.yaml (404),
  /asyncapi.json (404) and https://docs.signsealship.com/asyncapi.yaml (404) on 2026-09-01. The
  event surface is real and well documented in prose and in the OpenAPI management operations,
  but the OpenAPI declares no top-level `webhooks:` block at all -- so the event payloads exist only
  as documentation, never as a machine-readable contract. Publishing an AsyncAPI 3.0 document,
  or simply filling the OpenAPI 3.1 `webhooks:` block the spec already has room for, would make
  this surface machine-consumable at near-zero cost.
surface: webhooks
transport: HTTPS POST
delivery:
  method: POST
  content_type: application/json
  url_requirement: >-
    https only. A non-https URL is rejected with 400 {"error": "A https:// webhook URL is
    required."}
  headers:
  - name: SignSealShip-Signature
    format: 't=<unix seconds>,v1=<hex hmac>'
    note: >-
      During a 24-hour rotation overlap the header carries one v1 entry per active secret;
      accept the delivery when ANY v1 entry matches.
  - name: SignSealShip-Event
    note: Names the event topic.
  deduplication: >-
    Order-event ids are deterministic -- {topic}:{orderCode} -- so a redelivery deduplicates
    cleanly on the consumer side.
  payload_retention: >-
    Event payload bodies are never stored and never returned by the delivery-inspection
    endpoints; only attempt metadata is retained.
topic_count: 7
topics:
- name: passport.sealed
  family: passport
  description: A Proof Passport was sealed.
  available_via:
  - POST /api/passport/webhooks (passport-only shortcut; no topic list)
  - POST /api/partner/webhooks (topic-aware)
- name: room.order_attached
  family: room
  description: An order was attached to a Verified Closing Room.
  available_via: [POST /api/partner/webhooks]
- name: room.passport_sealed
  family: room
  description: A Closing Passport version was sealed for a room.
  available_via: [POST /api/partner/webhooks]
- name: order.created
  family: order
  description: An order was created through the Order API.
  scope: Delivers ONLY for orders the subscribing partner created through the Order API.
  payload_note: >-
    Shares one body shape with the other three order topics. Carries a deterministic id, the
    order's status name at dispatch time, and externalReference echoing the external_reference
    sent at order creation (omitted when none was sent).
  available_via: [POST /api/partner/webhooks]
- name: payment.cleared
  family: order
  description: Payment for an order cleared via the verified Stripe webhook.
  scope: Partner's own Order-API orders only.
  available_via: [POST /api/partner/webhooks]
- name: signature.completed
  family: order
  description: The signing ceremony for an order completed.
  scope: Partner's own Order-API orders only.
  available_via: [POST /api/partner/webhooks]
- name: shipment.delivered
  family: order
  description: The order's shipment was delivered.
  scope: Partner's own Order-API orders only.
  available_via: [POST /api/partner/webhooks]

auth:
  management: >-
    Partner bearer key OR the dashboard session cookie (__Host-session). Requires
    webhooks:read / webhooks:write per the operation descriptions.
  outbound: HMAC signature over the timestamped payload; the secret is shown exactly once.
operator_affordances:
- affordance: Signed test event
  operation: POST /api/partner/webhooks/{id}/test
- affordance: Signature verification recipe
  operation: GET /api/partner/webhooks/signature-example
  note: >-
    The API itself serves the verification recipe, and the docs publish working Node and Python
    verifier code. That is a materially better developer experience than most webhook surfaces.
- affordance: Delivery replay
  operation: POST /api/partner/webhooks/deliveries/{deliveryId}/replay
  note: Returns the NEW delivery's id plus replayedFrom.
- affordance: Cross-subscription delivery inspection
  operation: GET /api/partner/webhooks/deliveries?topic=
inbound_webhooks:
  note: >-
    Inbound vendor events (payments, notary sessions, shipping, mail) must pass signature
    verification before processing; if a vendor's verification is not configured the route does
    not exist in production. Fail closed, documented at https://signsealship.com/security.
plan_gate: >-
  Partner webhooks unlock at the $149/mo Pro Office tier. Partner Link explicitly does not
  include them.
gaps:
- No AsyncAPI document.
- >-
  The OpenAPI 3.1 document declares no top-level `webhooks:` block, though 3.1 supports one.
  Seven documented event payloads therefore have zero schema coverage.
- No published retry schedule or backoff policy for failed deliveries.
- No documented timeout for the consumer endpoint.
