note: >-
  The DataCandy API does not publish an AsyncAPI document, but it exposes a
  first-class Webhook Management surface: merchants register HTTPS callback
  endpoints (with an optional secret token) scoped to one or more merchants and
  a selected set of events. The event catalog below is derived verbatim from the
  Event schema enum in the OpenAPI. Webhooks are managed through the REST
  operations listed under management_operations.
delivery:
  transport: https-callback
  registration: REST (Webhook Management)
  callback_url_field: callbackUrl
  signing:
    field: secretToken
    note: Optional per-webhook shared secret set at registration time.
  scoping:
    merchants: Webhooks can be scoped to specific merchants via the merchants array.
    events: Each webhook subscribes to an explicit list of event types.
