description: >-
  FlowAccount exposes an event/webhook surface: registered integrations receive
  HTTP POST callbacks for FlowAccount events and can subscribe partner systems
  (e.g. the Page365 POS integration) to receive document/transaction notifications.
  Evidence: flowaccount/open-api apps/api/flowaccount-webhook (serverless.yml)
  defines a POST /webhook receiver and a POST /subscribe registration handler.
  No published AsyncAPI document was found and the full event-type catalog is not
  enumerated in public docs, so no channels are fabricated here.
