  of /asyncapi.yaml, /asyncapi.json and the GitHub org (AmeriCommerce/rest-api) on

  description: 'When the conditions for an event are met, the Online Store makes an
    HTTP request out to the subscriber URL. A subset of events are synchronous — the
    store waits for a response and uses it to change store behaviour (pricing, tax,
    discount, validation, payment authorization/capture).'
  response_timeout_seconds: 3
  response_timeout_note: Applies to events that expect a reply; the short timeout is
    deliberate because delays are user-visible in the storefront.
  response_caching:
    field: cache_length
    options:
    - {value: Short, meaning: 5 minutes}
    - {value: Long, meaning: 30 minutes}
    - {value: NoCache, meaning: do not cache the response}
  failure_handling:
    field: failure_type
    options:
    - {value: Ignore, meaning: 'disregard the failure and continue as normal (default)'}
    - {value: Error, meaning: display an error message to the user}
    - {value: Fallback, meaning: 'call the alternate URL in fallback_url'}
