The Universal Commerce Protocol (UCP) is an open-source standard designed to power the next generation of agentic commerce. By establishing a common language and functional primitives, UCP enables seamless commerce journeys between consumer surfaces, businesses, and payment providers. It is built to work with existing retail infrastructure, and is compatible with Agent Payments Protocol (AP2) to provide secure agentic payments support. It also provides businesses flexible ways to integrate via APIs, Agent2Agent (A2A), and the Model Context Protocol (MCP).
UCP is developed by Google in collaboration with industry leaders including Shopify, Etsy, Wayfair, Target, and Walmart endorsed by over 20 global partners across the ecosystem like Adyen, American Express, Best Buy, Flipkart, Macy's Inc, Mastercard, Stripe, The Home Depot, Visa, Zalando and many more.
The UCP conformance suite needs a way to move an order to shipped so it can check the order event that
follows. That is not part of UCP: the suite hardcodes the path POST /testing/simulate-shipping/{order_id}
and a Simulation-Secret header, copying the reference sample server.
The endpoint stays switched off until a secret is set in app/etc/env.php:
'universal_commerce' => [
'simulation_secret' => 'a-long-random-value'
],Remove the key to switch it off again. With no secret set the endpoint answers 404 as though it were
never routed, and it only ever ships orders that UCP placed itself — never the storefront's.
Do not set this on a production store unless you are running the suite against it.
