Shopify's Fall '26 Edition opens its catalogue and checkout to AI agents
Shopify released its Fall '26 Edition on October 28, 2026, which it calls Exponential. The update centres on opening its product catalogue, cart and checkout to any AI agent or app, rather than the broader set of 150-plus merchant changes. Shop.dev offers developers a single connection to the catalogue, cart and Shop Pay checkout without requiring an API key. Separately, every Shopify storefront now exposes WebMCP tools so browser agents can search, update carts and complete purchases with structured data, and the company says these capabilities are its own claims rather than independently verified results.
