Muse checks out with Shop Pay where Meta allows it

Thirteen days after Meta launched Muse on September 8 with Shop Pay marked “coming soon” as a payment option, the agent can now use Shop Pay on Shopify stores and complete purchases for its users, the Wall Street Journal reported. Shopify CEO Tobi Lütke and Meta’s Alexandr Wang announced the partnership on X on September 21, according to PYMNTS.

Agentic shopping works “in countries where Muse is supported,” a post on Threads says, and that list wasn’t spelled out. Shopify described Shop Pay to the Journal as its accelerated, one-tap checkout, the service that stores buyers’ shipping and billing information.

Until now, payments reached Muse through Stripe, which arrived with Muse Connectors, the platform where developers and businesses submit their own integrations. Notion and Granola are listed there too.

When PYMNTS tested Muse on September 9 with three tasks (reordering toilet paper on Amazon, ordering a Domino’s pizza and booking a Resy table), all three failed, a report on Yahoo Finance said. Muse routed payment through Link, Stripe’s checkout system, and Shop Pay was not yet live. The failures came down to what had to happen before Muse could try a task: Amazon credentials shared through a secure link, plus Gmail and Calendar each connected through a separate authorization flow. Doing the same reorder directly on Amazon took less than 30 seconds.

On the Shopify side, products in the Shopify Catalog are shared with Muse automatically, Yahoo Finance reported. That builds on Agentic Storefronts, which Shopify launched in December 2025 to make every eligible store selling in the US discoverable in AI agent channels by default.

Amazon went the other way. PYMNTS reported on September 20 that Amazon had barred Muse from its store, saying the agent could create privacy and security risks if it captures and stores customer credentials.
