notes: >-
  KeyBank publishes the webhook surface as an OpenAPI 3.0.2 "Webhooks" document
  describing the client-hosted callback endpoints it invokes for payment
  lifecycle alerts across ACH, Wire, and RTP. No AsyncAPI document is published;
  this artifact captures the webhook catalog (type: Webhooks).
