  title: Autopass Service Authorization Locations Sessions API
  version: '1.0'
  description: Autopass ("快速通") is a Taiwan mobility financial-services platform that lets channel brand partners embed license-plate-based parking payment into their car-owner apps. Partners register user license plates, surface partner parking locations (POIs), read parking sessions and orders, and receive entry/exit/billing/refund notifications. This description reflects the operations and response fields published in the Autopass partner documentation; it is an API Evangelist reconstruction, not a provider-issued spec.
