Decision guide
Agent checkout on Shopify: the merchant guide
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.

Limits to plan around
- No published per-order rate for the Agentic plan on its own page (2026-11-04).
- ChatGPT purchases run on the merchant's Shopify checkout in an in-app browser, not an agent-native ACP checkout.
- Shop MCP has no order webhooks at launch; agents poll get_checkout.
