Source: https://agentreadycheckout.com/guide/shopify Site: Agent Ready Checkout Last reviewed: 2026-11-04 Decision guide # Agent checkout on Shopify: the merchant guide In short Shopify co-developed UCP with Google, syndicates catalogs to AI chats through Agentic Storefronts, and exposes UCP Cart, Checkout and Order MCP servers to agents. Its stated cells: UCP (live), AP2 (announced). First open risk: ChatGPT no longer runs in-chat checkout (24 Mar 2026); ChatGPT is a discovery and referral channel, so do not plan ACP checkout revenue from it. ## Shopify in the matrix | Protocol | Status | Note | | --- | --- | --- | | ACP | no statement found | no statement found (2026-11-04) | | UCP | live | UCP co-developer; Cart, Checkout and Order MCP servers at /api/ucp/mcp; agent profiles self-serve since Spring '26 | | AP2 | announced | Shopify says UCP supports AP2 alongside REST, MCP and A2A; no Shopify AP2 mandate flow documented | | Visa TAP | no statement found | no statement found (2026-11-04) | | Visa IC | no statement found | no statement found (2026-11-04) | | Mastercard Agent Pay | no statement found | no statement found (2026-11-04) | | Agent Pay for Machines | no statement found | no statement found (2026-11-04) | | Amex ACE | no statement found | no statement found (2026-11-04) | | x402 | no statement found | no statement found (2026-11-04) | | MPP | no statement found | no statement found (2026-11-04) | | Link for agents | no statement found | no statement found (2026-11-04) | | Verifiable Intent | no statement found | no statement found (2026-11-04) | | | | 1 live or pilot of 12 | | | ## By size band ### Shopify, small #### Protocols that apply - [UCP](https://agentreadycheckout.com/protocols/ucp): [live](https://agentreadycheckout.com/matrix/ucp/shopify) on Shopify - [ACP](https://agentreadycheckout.com/protocols/acp): no statement found on Shopify - [Link for agents](https://agentreadycheckout.com/protocols/stripe-link-for-agents): no statement found on Shopify #### Channels - [ChatGPT](https://agentreadycheckout.com/surfaces/chatgpt-shopping) - [Google AI Mode](https://agentreadycheckout.com/surfaces/google-ai-mode-and-gemini-checkout) - [Copilot](https://agentreadycheckout.com/surfaces/microsoft-copilot) Agent surfaces your customers already use: ChatGPT (discovery), Google AI Mode and Gemini, Microsoft Copilot. #### Integration path Turn on Agentic Storefronts in Shopify Admin (ChatGPT, Copilot, Google AI Mode and Gemini) and keep Shopify Payments or your PSP; UCP Cart, Checkout and Order MCP servers are served for you; agents register self-serve profiles (Spring 26 Edition, 17 Jun 2026).
