Why Some Shopify Products Can't Be Bought in Muse (and What to Do)

Meta's Muse can now buy from Shopify stores with Shop Pay, and for eligible stores it's switched on by default. But "eligible" is doing a lot of work in that sentence. Some products and some store setups can't complete a purchase inside Muse, and Shopify doesn't send you an alert when one of yours is among them.

Here's every documented reason a Shopify product won't check out in Muse, grouped by cause, with the fix for each. The source for all of it is Shopify's help center page on selling on Meta.

This is part three of our AI checkout series. If you're just catching up, part one explains the Shopify and Muse deal.

First, figure out which problem you have

"Can't be bought in Muse" covers two very different failures.

• Muse never mentions the product. That's discovery. The product isn't in Shopify Catalog, or Catalog access for Meta is off, or Muse didn't understand the product well enough to recommend it.
• Muse finds it, but the shopper gets sent to your site to pay. That's checkout. Discovery worked, but something about the product or your store isn't supported by Meta's direct checkout.

The second is less bad than it sounds. The shopper still reaches your store with intent to buy. You just lose the one-tap Shop Pay experience inside the chat, which is where AI checkout earns its conversion lift.

Reason 1: The product type isn't supported

Shopify lists four product types that don't work in Meta's direct checkout:

• Subscriptions
• Product bundles
• Customizable products (engraving, monograms, build-your-own)
• B2B-only products

What to do: For subscriptions, consider whether a one-time purchase option on the same product makes sense. Muse can sell the one-time version in the chat, and subscribers can still sign up on your store. For bundles, a standalone product that represents a popular fixed bundle (with its own title, price, and inventory) often works better for agents than a dynamic bundle anyway, because it reads as a single clear thing. Customizable and B2B products are best left to your own checkout.

Reason 2: Your checkout relies on features Muse can't carry

These checkout features aren't supported in Meta's direct checkout:

• Checkout blocks
• Local delivery, in-store pickup, and pickup points
• Required customer sign-in before checkout
• Google Analytics and custom pixels (only server-to-server pixel events fire)
• Accelerated checkout options have only partial support

Discount codes, automatic discounts, and Shopify Functions for shipping, discounts, and cart and checkout validation do carry over.

What to do: The forced sign-in one is the easiest to fix and the most expensive to miss. If your store is set to require customer accounts, every AI direct checkout is off the table. In Settings > Customer accounts, make sign-in optional unless you truly need it (wholesale-only stores are the usual exception).

If a checkout block does something essential, like collecting a required gift message or age confirmation, move that logic somewhere that survives. A Shopify Function for validation carries over. A product option or line item property collected before checkout usually does too.

Local delivery and pickup stores can still sell shipped orders through Muse. The pickup buyers finish on your site.

Reason 3: Your store isn't in a supported region

Selling on Meta with direct checkout requires that you sell to customers in the United States, Canada, or Mexico. Muse itself launched in the US first.

What to do: If you ship to the US from elsewhere, make sure the US is set up as a market you actually sell to in Shopify Markets, with shipping rates configured. An agent can't sell a product it can't ship.

Reason 4: Missing store policies or channel setup

Shopify requires all of these for Meta's direct checkout:

• Terms of Service, Privacy Policy, and Return and Refund Policy filled in under Settings > Policies
• The Facebook and Instagram by Meta sales channel installed, with product syncing on
• The Shopify Agentic Storefronts Supplemental Terms of Service accepted

What to do: Open Settings > Policies and fill in every field. A refund policy that only exists as a theme page doesn't count. Then open Sales channels > Agentic > Meta and see if it flags anything.

Reason 5: Legal disclosures sit too far down the description

This one is easy to miss. Shopify says product descriptions must include relevant legal disclosures in the first 6,000 characters.

If you sell anything with required warnings (supplements, cosmetics, products with California Prop 65 notices, anything with age restrictions), and the warning sits at the bottom of a long description, it can fall outside what Meta's checkout reads.

What to do: Move required disclosures near the top. A short, clearly labeled "Warnings" line right after the opening paragraph is better for shoppers and agents alike.

Reason 6: The product isn't in Shopify Catalog at all

If Muse never mentions the product, start here. Shopify Catalog eligibility requires:

• A store on the Starter plan or higher, not in password-protected mode
• A title and at least one image
• A price greater than zero
• Publication to the Online Store, Hydrogen, or Headless channel, with an identifiable product URL
• Not Unlisted, and not hidden from search engines
• No sensitive or mature content

Account standing matters too: verified email, two-step authentication, a low chargeback rate, and good standing with Shopify Payments.

What to do: Run through our Shopify Catalog eligibility checklist, which covers each rule and the common ways stores fail them. The one that catches the most stores is products hidden from search engines through a theme setting or SEO app, often by accident. Also check that Shopify Catalog access is on for Meta under Sales channels > Agentic.

Reason 7: Muse didn't understand what the product is

A product can be eligible, in the Catalog, and fully supported by direct checkout, and still never get picked. The reason is almost always data.

Shopify Catalog shares your titles, descriptions, options, images, prices, and availability. When a shopper asks for "a linen shirt in navy, size large," the agent is matching those words against your fields. If your title is just the product's brand name, if color only appears in a photo, or if fabric is mentioned once in the third paragraph, the agent is guessing. Shopify has said inferred product details have varying accuracy, and a store that's easy to read beats one that's hard to read.

What to do: Put the category noun in the title. Use real variant options for size and color. Fill in category metafields for attributes like material and fit. We go deep on this in part four: what AI shopping agents read before they pick your product, and in how the Global Catalog guesses your category.

A quick audit you can run today

1. Filter your products by type. Count subscriptions, bundles, and customizable items. That's the share of your catalog that checks out on your site, not in Muse.
2. Check Settings > Customer accounts. Sign-in should be optional.
3. Check Settings > Policies. All three fields filled in.
4. Open Sales channels > Agentic > Meta. Catalog access and direct checkout on, no warnings.
5. Pick your best seller and read its title, options, and first paragraph as if you were an agent that can't see images. Would you know exactly what it is?

For the last step, AgentReady's free Shopify Catalog readiness checker looks at the product data agents rely on, including structured data, identifiers, and feed consistency, and shows you where the gaps are. It's the fastest way to see your products from the agent's side of the chat.
