Versions:
PayCoOrder 1.2.0.0, released by NHN PAYCO, Inc., is a lightweight Windows utility categorized under e-commerce and cloud-integration tools that acts as a secure local relay between Payco’s order-handling cloud services and merchant workstations. Installed as a background Windows service, the program listens on a designated localhost port, translates incoming HTTP or gRPC requests from point-of-sale, kiosk, or inventory applications into the authenticated Payco Order Cloud protocol, and returns structured JSON responses containing payment status, shipping instructions, or refund tokens. Because the relay keeps OAuth 2.0 refresh tokens and merchant certificates encrypted in its private store, desktop software that is not cloud-aware can still place, modify, or cancel Payco orders without exposing credentials to end-users. Typical use cases include on-premise retail outlets that run legacy POS code, warehouse PCs that print delivery labels when a Payco payment clears, and pop-up stores that need instant order mirroring while the internet connection is unstable. Version 1.2.0.0 is the first generally available build; it introduces TLS 1.3 tunneling, automatic token rotation every 60 minutes, and a silent installer that can be scripted through Windows Group Policy. Administrators can update the relay endpoint, throttle concurrent sessions, or switch between sandbox and production clouds by editing a single INI file, after which the service reconfigures without reboot. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
