WooCommerce Just Did What Shopify Did — Hours Later, Open Protocol, Full Autonomous Purchase

Hours after Shopify announced AI-powered purchasing via ChatGPT, a WooCommerce store completed a fully autonomous AI purchase using the open Universal Commerce Protocol (UCP), with identity linking, wallet payment, and order processing — all without any platform partnership. Unlike Shopify's bilateral ChatGPT deal, UCP is an open spec any store, agent, or platform can implement independently, supporting OAuth 2.0 identity linking, autonomous payment instruments, and MCP transport binding.
