Making Sense of the Agentic Commerce Protocol
Last week, OpenAI introduced the Agentic Commerce Protocol (ACP), and the e-commerce world is buzzing. Below, we break down what it is, why it matters, and what it means for Saleor and its customers.
Quick recap
ChatGPT now has ~800 million weekly active users. Many of them already use it to get product recommendations.
With ACP and Instant Checkout, OpenAI is extending ChatGPTâs role: not just to suggest products, but to complete purchases.
Agentic Commerce Protocol is an open protocol published by OpenAI & Stripe to standardize communication between agents, merchants and customers in an effort to enable universal, programmatic commerce flows. Since itâs a protocol, it could be adopted by other AI products (like Claude).
Instant Checkout is OpenAIâs implementation of that protocol within ChatGPT that allows certified (see "Merchant application form" at https://chatgpt.com/merchants) merchants to expose product catalogs, checkout logic, and payments interfaces to ChatGPT.
To support Instant Checkout, merchants need to implement three core domains: sharing a product feed, handling orders & checkout, and handling payments.
Why this matters
Itâs not every day that a new sales channel opens up to nearly a billion active users.
What makes this one different is the way LLMs combine personal context with access to vast product datasets across many merchants. That creates purchase journeys we havenât really seen before: less about browsing catalogs, more about agents stitching together tailored recommendations and transactions on the fly.
The ripple effects for e-commerce are still emerging, but we can already sketch some likely impacts:
APIs, not web pages
Your API surface (catalog + checkout) becomes the âshopfrontâ to AI agents. If your stack canât expose structured, agent-friendly endpoints, you can lose visibility in this new channel.
Modeling is the foundation
Agents will compare products across merchants using structured data. Better variant-level metadata, full attribute coverage, rich media, and real-time stock updates reduce âinformation asymmetryâ and mistakes.
Modeling will keep your APIs and ChatGPT happy, but what about your human visitors? To make them stay, you need to consider what the storefront itself can offer.
Storefronts need to differentiate
Agentic workflows introduce new pressure on traditional storefronts. If more product discovery and purchases happen directly in ChatGPT, less organic traffic reaches your site. This effect can already be observed in the AEO vs. SEO conversation.
That doesnât make storefronts irrelevant, but it does raise the bar. At a minimum, a storefront should be beautifully designed and easy to navigate. More importantly, it should provide something an agent interface canât: a curated, tailored experience that reflects your expertise in your domain.
For some merchants, that might mean immersive product pages with rich storytelling. For others, it could be custom configurators, guided wizards, or interactive tools that help customers make sense of complex choices. The point is that the storefront is still yours to shape, but it needs to deliver unique value that justifies the visit.
Reputation on the line
Until now, the entire order lifecycle - from checkout to shipping to refunds - was something only the merchant and customer could see. With agentic workflows, a third party is now in the loop. Just consider that your order processing will be observed by ChatGPT itself, not just your internal systems.
OpenAI already mentions âqualityâ as a ranking factor, though it doesnât spell out what that means. Itâs reasonable to expect that fulfillment delays, refund friction, or repeated issues could eventually affect how your products are ranked or surfaced.
How Saleor adapts to ACP
Weâre already seeing excitement from our customers about this new sales channel â and we want to make sure getting started is as smooth as possible.
Saleorâs app-based extensibility model is a perfect fit here. Instead of building custom integrations from scratch, merchants will be able to install the ACP App that we are building and connect directly to ChatGPTâs Instant Checkout flow with minimal setup.
Our goal is to become the first open-source commerce platform to support Instant Checkout with ChatGPT out of the box. Installing the Saleor ACP App, configuring it, and completing OpenAIâs merchant certification should be all you need to start selling through ChatGPT.
Agentic commerce is still new ground. You can count on us to be your partner in exploring it. Weâll stay active in shaping how this channel develops and ensure our customers can step in with as little friction as possible.
If youâd like to be part of the first wave, you can sign up for the ACP App beta here.
