Muse can buy. That does not mean your Shopify store can sell to it.

Meta's Muse launch is already being compressed into a simple story: AI agents can now buy from Shopify stores. That skips four separate states: An agent is announced. It can access product data. It can complete a payment flow. The merchant records an attributed order. Here is what the primary sources actually establish as of September 9: * Meta says Muse is rolling out in the US, can pay with Link, and will support Shop Pay soon. * Stripe says US users can connect Link. At merchants that accept Link, Muse can use the saved payment method. Elsewhere, Link can issue a single-use virtual card scoped to the approved purchase. * Shopify documents direct checkout on Meta surfaces for eligible stores and US-based shoppers, with product discovery powered by Shopify Catalog. The important gap: "direct checkout on Meta surfaces" does not establish that Shop Pay is already live inside Muse for every eligible store. If you are building or integrating a shopping agent, I would not call the flow production-ready until I could log: * the exact surface and shopper market; * the SKU and variant selected; * price, currency and stock at decision time; * the payment method and approval event; * the merchant order ID; * attribution, cancellation and refund state. Has anyone here completed a real Muse purchase and inspected the merchant-side order? Which link in that chain was hardest to verify?
