How agents pay with Shop Pay
Stores list the payment methods agents may use in their UCP profile, under payment_handlers. Shop Pay appears as dev.shopify.shop_pay. An agent that sees it can get a Shop Pay token for the buyer, with the buyer's approval, and submit it at checkout. The agent never sees the card number.
Claude Duet pays this way: Anthropic describes it buying from online stores with Shop Pay and asking the buyer to approve each spend.
What happens without it
The agent can still build a cart and hand the buyer a link to your checkout, but the purchase leaves the conversation. Every extra step loses buyers, and an agent comparing stores can complete the order somewhere else instead.
How to turn it on
Turn on Shop Pay in Shopify admin under Settings → Payments. For Shopify stores, Shopify then advertises Shop Pay to agents in the store's UCP profile automatically. There's nothing to install.
To confirm, open https://yourstore.com/.well-known/ucp and look for dev.shopify.shop_pay, or run the free AI shopping readiness checker, which reports it.

Agents can't check out in the conversation
