PrestaShop and Agentic Commerce: 250,000 Merchants Have No Seat at the Table

Google and OpenAI built their commerce protocols around Shopify. PrestaShop’s 250,000+ merchants are on their own.

Last week at NRF, Google unveiled the Universal Commerce Protocol . The list of co-developers: Shopify, Walmart, Target, Etsy, Wayfair. The list of payment endorsers: Visa, Mastercard, Stripe, Adyen, American Express.

PrestaShop is not on either list.

OpenAI’s Agentic Commerce Protocol launched in September with Shopify and Etsy. PrestaShop is not there either.

For the 250,000+ stores running PrestaShop, many of them in France, Spain, Italy, and Latin America, the two biggest shifts in ecommerce are happening without them.

What exists today

Let’s be precise about what PrestaShop merchants can and can’t do right now.

ACP (ChatGPT Instant Checkout)

Third-party solutions have started to appear. ACPFeed offers an integration platform that connects PrestaShop stores to ChatGPT via ACP. They handle the product feed, the checkout API, and OpenAI certification. Setup is quoted at 2-4 weeks.

A dedicated ChatGPT Product Feed module generates XML product feeds compliant with ACP, making your catalog visible inside ChatGPT conversations.

These are early, third-party tools. They work, but they’re not backed by PrestaShop itself.

UCP (Google AI Mode)

Nothing exists. No module, no plugin, no official support.

As PrestaShop expert Nicolas Dabene wrote after the NRF announcement : a “UCP Connector” module for PrestaShop is technically possible, but “no implementation has been tested or validated in production to date.”

UCP envisions stores exposing capabilities via a JSON file at /.well-known/ucp, declaring what transactions the store supports. It’s modular: discovery, checkout, and fulfillment are separate capabilities. A PrestaShop module could implement this. But nobody has built it yet.

Google Merchant Center (your strongest card)

This is where PrestaShop merchants have an advantage they may not realize.

PrestaShop has had Google Merchant Center integration for years. The official “PrestaShop Marketing with Google” module syncs your catalog to Merchant Center in real time: products, prices, availability, attributes.

When Google’s AI Mode starts surfacing products from the Shopping Graph, your Merchant Center feed is what it reads. You don’t need UCP for that. You need a clean, complete feed.

The European problem

This isn’t just a technical gap. It’s a market access problem with a geographic dimension.

PrestaShop is the leading open-source ecommerce platform in France and a major player across Southern Europe and Latin America. These are exactly the markets that are underserved by the current agentic commerce ecosystem:

ACP is US-only. ChatGPT Instant Checkout works only for US merchants selling to US buyers.
UCP is rolling out in the US first. Google AI Mode checkout is available to eligible US retailers.
Perplexity Shopping is US-only.

European PrestaShop merchants face a double barrier: their platform has no native protocol support, and the protocols themselves don’t serve their geography yet.

This will change. OpenAI has said European expansion is planned. Google’s UCP is an open standard designed for global use. But right now, European merchants are waiting on both their platform and the protocols themselves.

What PrestaShop merchants should do now

The protocols will catch up to PrestaShop. The question is whether your product data will be ready when they do.

Get your Google Merchant Center feed in shape. This is the most impactful thing you can do right now. Install the “PrestaShop Marketing with Google” module if you haven’t already. Make sure every product has: GTIN or EAN, accurate pricing, real-time stock status, complete attributes (size, color, material, brand), and factual descriptions.
Clean your structured data. Add Schema.org markup to your product pages: Product, Offer, Review, AggregateRating. Every AI shopping surface, from ChatGPT to Google to Perplexity, uses structured data to identify and rank products. PrestaShop themes vary widely in Schema.org support. Check yours.
Consider the ACP third-party options. If you’re a US merchant on PrestaShop (they exist), ACPFeed and the ChatGPT Product Feed module can get you into ChatGPT conversations now. The integration isn’t trivial, but the tools are available.
Write product descriptions for machines, not browsers. AI agents extract facts: “waterproof, 300g, fits laptops up to 14 inches, made in Portugal.” They ignore “discover our exclusive collection crafted with passion.” Rewrite your top products for attributes, not adjectives.
Watch the PrestaShop community. If a UCP module appears, it will likely come from the open-source community before PrestaShop itself ships anything. The PrestaShop forums and GitHub are where to look.

The bigger picture for European merchants

Agentic commerce is being built in San Francisco for American consumers. That’s where the protocols are designed, where the checkouts work, and where the first merchants are going live.

But every protocol announcement includes the same line: “expanding internationally.” Google’s UCP is an open standard. ACP is an open protocol. The infrastructure is being built to go global.

European merchants who prepare their product data now will be ready when the protocols arrive. Those who wait for PrestaShop to ship native support may find that their competitors, the ones on Shopify or WooCommerce with ACP plugins, got there first.

The platform you’re on matters less than the data you expose. A PrestaShop store with perfect product data and a clean Merchant Center feed will outrank a Shopify store with thin descriptions and missing GTINs, on every AI surface.
