Instant Checkout for Merchants in ChatGPT (chatgpt.com)

OpenAI announced Instant Checkout in ChatGPT, letting users buy products directly inside conversational searches. Built on the Agentic Commerce Protocol (ACP) — an open standard co-developed with Stripe — the feature surfaces merchant products ranked by relevance and enables seamless in-chat purchases. Discovery is free; merchants pay a small fee only when a sale occurs (refunded on returns). Importantly, merchants remain the merchant of record and retain full control over orders, payments, fulfillment, and customer relationships. The capability is live in the U.S. with merchants like Etsy already integrated and Shopify coming soon; merchant onboarding is rolling and available by application. Technically, ACP is designed as a flexible, interoperable layer for “agentic commerce” that lets AI agents transact with businesses without forcing platform lock‑in. Stripe customers can enable payments with a single line of code, while businesses on other processors can connect via Stripe’s Shared Payment Token API or ACP’s Delegated Payments spec — all without changing existing systems. ACP aims to scale as AI interfaces evolve, providing a future‑ready standard for payments, product feeds, and agent-driven shopping workflows. Merchants interested in integrating product feeds and Instant Checkout can apply now for phased onboarding.
