If your Shopify store is eligible for Shopify Catalog and sells to US customers, ChatGPT can read your products by default. You don’t need an app, a feed or an application to OpenAI. Shopify says “you don’t need to do anything” for discovery through Shopify Catalog. OpenAI says “no additional work is required from individual merchants.”

Both statements are about the connection. Neither covers what travels through it. Staying eligible, completing your policies, pointing Shopify Catalog at the right fields, writing facts a shopper can check, keeping price and stock true, and deciding whether to keep ChatGPT’s access on are all yours. Which products ChatGPT shows is ChatGPT’s decision. Shoppers who pick yours buy on your own checkout.

This page keeps the two companies’ statements apart, because they don’t always say the same thing. Checked on October 27, 2026; re-check before acting.

The checklist: automatic, yours, or neither

Each row is one task. The middle columns quote or paraphrase what each company’s current page says. “Not documented” means we didn’t find it in the pages listed under Sources. The last column is what to do.

Automatic, once you’re eligible

Task What Shopify says What OpenAI says Your check
Connecting your catalog to ChatGPT The ChatGPT channel is “active by default for eligible stores”. You “don’t need to do anything” for discovery through Shopify Catalog Shopify merchants’ product data is “already integrated into ChatGPT through Shopify Catalog”. No application needed Confirm you’re eligible (next table)
Sending product data Catalog sends title, description, options, images, price, availability and other key attributes, and “continuously updates” them Prices come from third-party providers; price and shipping changes “may” take time to appear Change a price and note when you see it change downstream
Grouping identical products Catalog consolidates variants and groups identical items. The Global Catalog clusters results by a Universal Product ID with offers from several merchants Once a shopper selects a product, ChatGPT may list several merchants offering it Know who else sells your exact product
Writing some fields for you Several catalog fields, including the description, specs and features, are marked Inferred: generated or enriched by Shopify, possibly inaccurate ChatGPT “may generate simplified product titles and descriptions” Compare what you wrote with what goes out
Serving store information to agents Every store serves /agents.md, /llms.txt and /llms-full.txt automatically; they don’t replace Shopify Catalog Not documented Read your own /agents.md once
Fees No fees for selling in ChatGPT, only standard payment processing “No fees on purchases that start in ChatGPT” Nothing

Yours to do

Task What Shopify says What OpenAI says Your check
Store eligibility Starter plan or higher, not password-protected, and good account standing reviewed over time. Agentic-plan exception: a store on the Agentic plan that hasn’t published its online store to a paid plan can still be included Not documented for the Shopify route Sales channels > Agentic shows a product count or “Ineligible” (per Shopify; we haven’t seen the screen)
Selling to US customers Required. The store “can be based outside the United States” Shopping is “currently live for ChatGPT users in the U.S.” Confirm you sell and ship to the US
Store policies Terms of service, Privacy policy, and Return and refund policy must be completed Not documented for the Shopify route Open each policy page and check it isn’t blank
Supplemental Terms You must read and agree to the Agentic Storefronts Supplemental Terms Not documented Confirm they’ve been accepted
Product eligibility Title, at least one image, price above zero, published with a URL, not Unlisted, not in an excluded category. Shopify classifies categories from your product information Prohibited products can be removed from results Spot-check five products
Prohibited products Products on OpenAI’s prohibited list don’t display in ChatGPT results Its policy names examples such as adult content, age-restricted products, weapons and prescription-only medicines Check your edge-case products
Which fields Catalog reads Change the title and description source on the Channel mapping page; changes apply with a delay Not documented If your best facts live in a metafield, map it
Variant grouping and list price Custom variant grouping; choose price or compare-at price as the list price Not documented Only use compare-at if it was really the regular price
Facts in your text Put relevant legal disclosures in the first 6,000 characters of the description ChatGPT weighs relevance to the shopper’s query and context, and may simplify descriptions Put the fact customers ask about most in the first sentence, with its unit
Price and stock accuracy Catalog sends your latest inventory and prices Availability and price are named factors in which merchant is listed Fix price and stock at the source, in Shopify
Keeping or removing ChatGPT’s access Turn off Allow Shopify to manage for me, then turn off ChatGPT’s Shopify Catalog access. It can take up to 7 days Not documented Decide deliberately, and write down the date
Hiding a product from all AI channels Set it to Unlisted, which also hides it from sitemaps, Google and your own store search Not documented Use only when you mean it

Neither you nor Shopify decides

Task What Shopify says What OpenAI says Your check
Which products ChatGPT shows Inclusion doesn’t guarantee a product appears in an AI answer or ranks in a position. Each channel controls final ranking, wording and experience A product appears when ChatGPT “perceives it to be relevant to your intent”, using the query and context such as Memory or Custom instructions Make your facts specific and true; you can’t make the choice
Which seller is listed Not documented Merchants ranked on “factors like availability, price, quality, and whether they are the maker or primary seller” If you resell, know who the maker is
Labels and review summaries Shopify’s listing quality counts only reviews verified by trusted sources Labels are generated and “not guarantees or verified statements”. Review summaries come from public websites and are “not verified by OpenAI” Earn real reviews; don’t chase a label
Checkout ChatGPT shoppers complete purchase on your online store checkout, in an in-app browser or a new tab. There’s no ChatGPT direct-checkout setting Help article: Instant Checkout for “some eligible products and merchants”. Merchant page: “moving away from a standalone Instant Checkout”, with purchases on merchant sites or apps Plan for shoppers arriving at your checkout
Reporting The Agentic section reports sales, orders, sessions and conversion per AI channel; not yet for headless stores Not documented Read the ChatGPT line monthly

Where the two companies’ statements differ

Three places are worth knowing about.

Checkout. Shopify calls ChatGPT a “discovery-focused referrer” and lists no checkout switch. OpenAI’s merchant page agrees that purchases happen on merchant sites. But on the same day, OpenAI’s help article still described Instant Checkout for some merchants. Our own October 26 snapshot fits the Shopify reading: all 1,620 Shopify Catalog results had native checkout set to false on their first variant, in one unpersonalized context. For a Shopify store, assume the click comes to you.

What “no work” means. Shopify says you don’t need to do anything for discovery. It also lists four requirements to sell on ChatGPT. OpenAI says no additional work is required. Both are true of the connection, and neither removes Shopify’s eligibility rules.

Direct feeds. OpenAI invites merchants to apply for a direct product feed for the most up-to-date information. Its merchant page says Shopify catalogs need no application. Whether a Shopify store gains anything from a direct feed as well isn’t documented in either company’s pages. Our feed guide covers the direct route.

Worked case: a Canadian store selling into the US

This is a labelled hypothetical: a Shopify store based in Canada, on a plan at Starter level or higher, selling winter boots to both Canadian and US customers. Here’s how the checklist sorts it out.

Question Answer for this store Source of the answer
Can a Canadian-based store take part? Yes, if it sells to US customers Shopify: the store “can be based outside the United States”
Plan Meets the Starter-or-higher rule Shopify Catalog requirements
Will Canadian shoppers see it in ChatGPT shopping? Not documented. OpenAI says shopping is live in the US and plans to expand OpenAI merchant page
Policies It must complete Terms of service, Privacy policy, and Return and refund policy Shopify, Selling on ChatGPT
Does it need to apply to OpenAI? No OpenAI and Shopify both say so
Checkout US shoppers who choose its boots buy on its own Shopify checkout Shopify, Selling on ChatGPT
Its key fact: “rated to −30 °C” Its job: say what was rated, how and to which part of the boot, in the first sentence Our proposal

That last row matters more than it looks. In our October 26 catalog snapshot, one snowsuit listing’s description rated the hood’s insulation to −30 °C, while another’s title said “protects to -30 °C”. Both say minus 30. Only one tells you which part. And Shopify’s generated spec line for the hood listing dropped the word “hood”. Shopify marks generated fields Inferred, and OpenAI says ChatGPT may simplify descriptions, so a qualifier can get lost twice. Write it plainly in your own first sentence (“hood insulation rated to −30 °C”) and check what comes out the other end. Precision in the source text is the one part of this chain that’s entirely yours.

How we checked

On October 27, 2026 we read Shopify’s help pages on selling on ChatGPT, agentic storefronts, managing agentic storefronts, Shopify Catalog, Catalog requirements, product discovery and Catalog mapping, plus Shopify’s Global Catalog developer page. On the same day we read OpenAI’s help article on shopping with ChatGPT and its merchant page. Every row attributes a statement to the company whose page contains it. We didn’t log into a Shopify admin, so menu names come from Shopify’s help text. The checkout and snowsuit observations come from our saved Shopify Catalog snapshot of October 26, 2026, with no buyer or country context. For the full cross-channel responsibility map, see Shopify Agentic Storefronts; for the admin section itself, see the Agentic tab.

Your next step

Work through the “Yours to do” table for your store today. Write the date and what you found in the last column of every row. Any row you can’t fill in is either a setting to check in your admin or a fact to add to your product text. When it’s done, see ChatGPT product recommendations for what to check next, product by product.
