AsyncAPI Specification

spec_type: Webhooks
note: >-
YBS implements the OBIE Read/Write Event Notification model. An onboarded TPP
manages subscriptions via the Event Subscriptions API and receives event
notifications (OBEventNotification2, a signed JWT / security event token) for
changes to Open Banking resources - most notably consent revocation. No
AsyncAPI document is published by YBS; this captures the webhook/event surface
it does operate. Not fabricated - the subscription operations are real
OpenAPI operations.
