note: >-
  Discover documents a real outbound event surface but publishes no AsyncAPI document, no event
  catalogue and no payload schemas for it. Nothing is fabricated here - this file records the
  webhook surface exactly as Discover describes it and marks the gaps.
webhooks:
- name: Account Notification API
  direction: outbound
  transport: HTTPS webhook - Discover calls an endpoint the token requestor hosts
  description: >-
    "The Account Notification API connects DFS Services LLC with the token requestor by
    transmitting issuer-initiated updates applied to Cardholder accounts."
  requirement: >-
    "Token requestors must integrate with this endpoint to receive issuer notifications via
    webhooks."
  product: Discover Stored Token Services (DSTS)

security:
  model: Outgoing API Authentication
  mechanisms:
  - mutual TLS 1.2 / 1.3 with a root CA and a partner client certificate
  - Second Factor JWT (JWS) signed by Discover, validated by the partner against the Discover
    JWS public keys and KID
  - JWE payload encryption where the notification carries sensitive data
  signature_verification: >-
    Partners validate Discover-signed responses and outbound calls with the Discover JWS public
    keys published at the JWKS endpoint (authentication/discover-jwks.json).

gaps:
- No AsyncAPI document.
- No named event types and no notification payload schema.
- No retry, ordering, replay or signature-header contract for webhook delivery.
- The subscriber-side endpoint contract (what URL Discover calls, how it is registered) is not
  published - it is settled inside partner onboarding.
