How to Let Customers Check Out With AI on Your Shopify Store

If you want customers to buy from your Shopify store through an AI assistant, most of the plumbing is already in place. Shopify connects eligible stores to ChatGPT, Google AI Mode, Gemini, Microsoft Copilot, and Meta's Muse through Shopify Catalog and Agentic Storefronts. On four of those five, the shopper can finish the purchase without leaving the assistant.

Your job is smaller than most guides make it sound. Make sure you're eligible, make sure nothing blocks checkout, and make sure the assistant can understand your products well enough to pick them.

This is part two of our series on AI checkout. Part one covers the Shopify and Meta Muse deal that kicked it off.

Discovery and checkout are two different switches

Almost every confused conversation about "selling in ChatGPT" comes from mixing these up.

Discovery is whether an assistant can find and recommend your products. On Shopify, that runs through Shopify Catalog, the cross-merchant product index that AI channels search. It's controlled by the Shopify Catalog access toggle for each channel.

Checkout is whether the shopper can pay inside the assistant. That's the Direct checkout toggle. When it's off, or the channel doesn't offer it, the assistant links the shopper to your online store to finish.

You can have discovery without checkout. You can't have checkout without discovery. And checkout is only worth anything if discovery works, because an assistant can't sell a product it didn't recommend.

Which AI assistants can check out on Shopify

Based on Shopify's Agentic Storefronts documentation as of late September 2026:

ChatGPT is the odd one out. OpenAI's Instant Checkout was effectively retired earlier this year, so today ChatGPT hands the shopper to your own checkout. We explain what that means in Buy It in ChatGPT: What It Means for Shopify Merchants.

This table will change. Channels get added and checkout options shift, so treat your admin as the source of truth, not any blog post, including this one.

How to set up AI checkout on Shopify, step by step

1. Confirm your store and products are Catalog-eligible

Nothing else matters if your products aren't in Shopify Catalog. The store needs to be on the Starter plan or higher with no password page. Each product needs a title, at least one image, a price above zero, a reachable product URL, and publication to the Online Store, Hydrogen, or Headless channel. Products marked Unlisted or hidden from search engines are excluded.

Our Shopify Catalog eligibility checklist goes through each rule and how to verify it. Shopify's own list is on the Catalog requirements page.

2. Fill in your store policies

Go to Settings > Policies and complete the Terms of Service, Privacy Policy, and Return and Refund Policy fields. Meta's direct checkout requires all three, and agents quote return terms back to shoppers. A policy that only exists as a page in your theme doesn't count.

3. Install the channel-specific pieces

Some channels need an extra connection. For Meta, Shopify requires the Facebook and Instagram by Meta sales channel with product syncing turned on. Open each AI channel under Sales channels > Agentic and it will tell you if something is missing.

4. Review the Agentic settings

Open Sales channels > Agentic. By default, Allow Shopify to manage for me is on, which means Shopify decides channel participation for you. That's a sensible default for most stores.

If you want control per channel:

1. Turn off Allow Shopify to manage for me.
2. Click the channel, for example Meta.
3. Set Shopify Catalog access (discovery) and Direct checkout (paying in the assistant).
4. Click Save.

You'll also need to have accepted the Shopify Agentic Storefronts Supplemental Terms of Service.

5. Check for products that can't use direct checkout

Direct checkout in AI channels is narrower than your regular checkout. On Meta, for example, subscriptions, bundles, customizable products, and B2B-only products can't be bought in the assistant, and stores that force customer sign-in before checkout aren't supported. Part three of this series, Why some Shopify products can't be bought in Muse, covers the full list and the workarounds.

6. Make sure the assistant can understand what you sell

This is the step Shopify can't do for you, and it's the one that decides whether you get the sale.

An assistant only recommends what it can match to the shopper's request. If someone asks Muse for "a merino base layer in a men's medium," the agent needs to know your product is merino, a base layer, for men, and available in medium. If that information lives in a paragraph of description copy instead of product options, category metafields, and a clear title, the agent has to infer it. Sometimes it guesses right. Often it moves on to a store that made it easy.

We break down exactly what agents read in part four.

7. Run a test and watch your orders

Once it's live, ask the assistants for things you sell, in the words a customer would use. See whether you come up. When AI orders arrive, check how they're attributed in your admin. Part five covers tracking, including the pixels that don't fire on AI checkouts.

Should you leave direct checkout on?

For most stores, yes. There's no Shopify fee on top of payment processing for Meta's direct checkout, you stay the merchant of record, and every extra step between "I want this" and "paid" loses buyers. An assistant checkout with Shop Pay is about as short as a purchase gets.

A few cases where you might turn it off for a channel:

• Your checkout relies on checkout blocks or custom pixels that carry real business logic, like age verification or a required gift note.
• You need local delivery or pickup, which AI direct checkout doesn't support.
• You want every buyer to land on your site for an upsell or post-purchase flow and you've measured that it pays for the lost conversions.

Even then, leave Catalog access on. Turning off checkout keeps you discoverable. Turning off Catalog access mostly just hands the recommendation to a competitor.

Where AgentReady fits

Shopify handles the connection to every AI channel. What it doesn't tell you is how your products look to an agent, and whether the details a shopper asks about are actually machine-readable.

That's what AgentReady is for. It checks your products against Shopify Catalog eligibility, flags the ones with missing categories, barcodes, or attributes, and suggests fixes you can review and apply to Shopify, so your products are easier for an agent to match. If you want a quick read first, the free Shopify AI readiness checker scans your storefront the way an assistant reads it, and the Catalog readiness checker focuses on the product data Shopify Catalog uses.

Neither one promises that an assistant will pick you. They show you what the assistant can see, which is the part you control.
