How Meta Muse pays: Link, Shop Pay, PayPal and the fee

Muse, the agent Meta launched on 8 September 2026 (not Muse Spark the model or Muse Image the image model), pays through other people's rails: a Link by Stripe one-time card, the shopper's saved card, Shop Pay and PayPal. None adds a merchant fee today. Meta's own cut is one keynote sentence with no rate, date or payer.

Last updated: 26 September 2026.

Meta Muse pays with Link by Stripe, which issues a one-time card per purchase, or logs into the shopper's account and uses a saved card. Shop Pay and PayPal also work. Merchants pay standard processing only; Meta's fee is undisclosed.

The rails table

The setup checklist is in Meta Muse for merchants.

Rail 1: Link by Stripe, the recommended path

Meta's Help Centre page "How Muse works with payments" puts Link first: "Link keeps your payments safe by issuing a one-time card number for each purchase, so your real card number stays private. When you use Link by Stripe, Stripe offers coverage for eligible purchases for damages, theft, loss, price drops and returns" (Meta Help Centre, read 26 September 2026).

Stripe's newsroom post describes the two branches. "At more than 1 million businesses that accept Link, Muse can check out instantly using a US consumer's preferred payment method saved in Link." And: "For other businesses, Link issues Muse a single-use virtual card scoped to the approved purchase." In both, "For every purchase, consumers are asked to approve the transaction total directly in the chat interface, and Muse never sees their underlying payment details" (Stripe, 8 September 2026). The agent wallet is US only.

Rail 2: the shopper's own login and saved card

Meta's second method skips Link. "When Muse logs in on your behalf using credentials saved in the Secure Credential Store, Muse can make purchases on your behalf. Muse will ask for your approval prior to completing a purchase" (Meta Help Centre, read 26 September 2026).

This is the least visible rail: an order on an existing customer account, on a card it already holds, from a browser session. Nothing marks it as an agent purchase. Meta settles liability in one line: "You're responsible for all transactions that your Muse makes on your behalf."

Rail 3: Shop Pay

Announced on 21 September 2026, it went live on 24 September 2026: "Shop Pay is now available as a wallet in @Muse" (Shopify on X, 24 September 2026).

Shopify's Help Center carries the merchant terms (read 26 September 2026). Money: "There are no fees associated with selling in Meta's direct checkout. You pay only your standard payment processing fees." Reporting: "Orders that customers place on Meta surfaces are attributed to Meta."

Shop Pay is not yet on Meta's own payments page; the shopper-facing description of the wallet is Shopify's.

Rail 4: PayPal

PayPal joined on 22 September 2026: customers can "shop and check out using their Muse personal AI agents across PayPal merchants worldwide" (PYMNTS, 22 September 2026; American Banker, 23 September 2026). We found no PayPal newsroom post, and PayPal has not said which token a Muse order rides, so treat one as a normal PayPal-funded order. The mechanics of tokens, scoped grants and one-time cards are in how AI agent payments work.

What each rail means for the merchant

Merchant of record. On every live rail, you are. Meta: "All orders are fulfilled by the merchant that you purchase from" (Meta Help Centre, read 26 September 2026). Shopify: "You remain the merchant of record, and you continue to manage fulfillment, returns, and customer service for these orders" (Shopify Help Center, read 26 September 2026). Muse is a buyer's browser and a wallet, not a marketplace.

Fraud rules. The single-use card is the rail to check: a fresh card number, card-not-present, from a data centre, billing name matching a real person. A velocity or new-card rule written for card testing declines it. Stripe "might run fraud checks depending on your Radar setup" and offers an optional order approval hook per checkout (Stripe docs, read 26 September 2026).

Disputes and returns. Stripe: "your existing refund flow works without changes for agentic checkouts. Manage refunds and disputes on the Transactions page in the Dashboard." For shared payment tokens, "Subsequent events, such as refunds and reporting, behave as if you provided the PaymentMethod directly" (Stripe docs, read 26 September 2026). The new part: Link offers shoppers coverage for "price drops and returns" on your goods, while Meta tells the same shopper they are "responsible for all transactions". Keep your return policy current; the agent reads it before approval, and the dispute lands in your normal queue.

Attribution. A Shop Pay order is attributed to Meta in admin, but "Google Analytics and custom pixels won't fire in Meta's direct checkout" (Shopify Help Center, read 26 September 2026). A Link one-time card order carries no Muse marker; it is a guest order. A saved-card login order looks like the customer buying it themselves. In GA4, all three file as Direct or returning. We documented that gap in the MyMuse case study and the wider problem in dark agentic commerce traffic.

Payment is the last step: Muse first has to read the page, resolve the variant and find a checkout it can finish, which is the part that runs when you connect Tru Commerce from Muse. The surface itself is covered in Meta AI and Muse for brands.

The fee: what Meta has said and what it has not

At Connect on 23 September 2026, Mark Zuckerberg said: "Muse also has a novel business model. We believe that Muse will make you money. We're standing behind this by making Muse free for a huge number of tokens with the expectation that over time we will profit by taking a small fee from transactions" (Medianama, 24 September 2026).

That is the whole primary record: no rate, no start date, no scope, no statement of who pays. Trade coverage has read "the merchant" into it; Meta has not. The only merchant-facing document with a number is Shopify's, and the number is zero (Shopify Help Center, read 26 September 2026).

Two comparators frame it. OpenAI charged Shopify merchants "a 4% fee on sales made through ChatGPT checkout", while Google AI Mode and Copilot checkouts carried no extra fee (PYMNTS, 21 January 2026); OpenAI retired Instant Checkout in March (CNBC, 24 March 2026). Amazon's referral fee is a per-category percentage of each sale; its 2026 notice says "no increase to US Referral fees in 2026", with no percentages on that page (Amazon Selling Partners, 15 October 2025). Budget nothing for Meta's fee, and track it.

Where Tru Commerce fits

We have run this on Gray Porter and a group of US DTC brands: we made the product pages and checkout readable and finishable by an agent, then placed a real Muse order on the store. To see what a Muse order looks like at your own checkout before one arrives unannounced, book a demo.
