Shopify AI agent checkout

A Shopify store can be selling under two agentic checkout patterns at once: an assistant sending a shopper to your own checkout in an in-app browser, and an assistant completing the purchase inside its own channel on Shopify-powered checkout. The two fail in different places, so a merchant needs both their storefront data and their checkout to hold up rather than choosing which one to care about.

A Shopify store can be selling under two agentic checkout patterns at the same time, and they place the risk in different places. Knowing which one a given assistant uses is what tells you whether your problem is your data or your checkout.

Where an agent purchase actually completes Two live patterns. In the first, the assistant sends the shopper to the merchant's own checkout. In the second, the purchase completes inside the assistant's channel. A single store can be selling under both at once. PATTERN ONE Assistant finds the product In app browser opens your site Your checkout Your checkout is the checkout. What stalls in it stalls a sale the assistant had already sent you. PATTERN TWO Assistant finds the product Checkout inside the channel the shopper never leaves the chat Your catalogue data has to carry the sale on its own.
Both patterns are live at once. A single store can be selling under both.

Pattern one: the shopper lands on your checkout

Shopify’s help centre says ChatGPT users "complete their purchase on your online store checkout in a ChatGPT in-app browser, or in a new tab when customers use ChatGPT web". So your ordinary checkout is the checkout, driven on a narrow mobile viewport in a fresh session with nothing warm.

That is good news commercially: you keep the customer, the order data and a checkout you control. It is also a larger obligation, because a checkout problem now costs you the order outright rather than a place in somebody else’s flow. See how to test checkout in an in-app browser.

Pattern two: the purchase completes in the channel

The same Shopify documentation says shoppers using Google AI Mode, Gemini or Microsoft Copilot complete their purchase "in the AI channel’s Shopify-powered direct checkout without having to leave their chat conversation".

Here your checkout is not in the path at all, which means your product data carries the entire sale. Price, availability at variant level, identifiers and terms decide whether you are chosen, and there is no page for a shopper to look at if the data is thin.

What this means in practice

Because both patterns are live, the work does not divide neatly. What it does do is set an order.

  1. Product data first, because it is the only thing that matters in both patterns. See how to add product schema for AI agents.
  2. Feed second, because it decides whether you are cheap enough to consider. See Shopify product feeds for AI agents.
  3. Checkout third, and specifically checkout in a cold in-app browser rather than checkout in general.

The part that is already switched on

Shopify’s documentation says agentic storefronts are active by default for eligible stores. A merchant reading this may already be receiving agent traffic and already failing it, without having made any decision at all.

That is the argument for checking rather than planning: see is your Shopify store agent ready and Shopify agentic storefronts explained.

Questions

Do I have to turn any of this on?

Shopify’s documentation says agentic storefronts are active by default for eligible stores, which means a merchant can already be taking agent traffic without having opted into anything. The practical implication is that this is worth checking rather than deciding.

Which pattern should I optimise for?

Both, because they fail in different places. In-channel checkout is decided almost entirely by your product data. Checkout on your own store is decided by your data and then by whether your checkout survives a cold session in a narrow in-app browser.

Does this change my fees?

Shopify’s help centre currently says there are no fees associated with selling in ChatGPT and that you pay only your standard payment processing fees. A widely repeated four percent figure could not be confirmed against a primary source, which is covered in the Contested section of the state of agentic checkout page.
