Agentic payment: when AI buys on behalf of consumers

With agentic payment, artificial intelligence doesn't just recommend products — it advises consumers, personalises their journey, and completes online transactions on their behalf.

This next chapter in e-commerce is reshaping the relationship between merchants, payment systems, and customers. It represents a major growth opportunity for businesses that position themselves ahead of its arrival in Europe.

So how do you prepare for agentic payment? Here is everything you need to know about what is already possible today — and what is coming in the months ahead.

Agentic payment: the essentials

Definition

Agentic payment refers to a new way of shopping online: an autonomous artificial intelligence searches, compares, and purchases products or services on behalf of a user.

"Agentic payment" is the umbrella term for payment conducted through AI agents. However, it is worth distinguishing between agentic payment and agentic commerce more broadly.

What is the difference between agentic payments and agentic commerce?

• Agentic commerce: involves making a product catalogue available via a large language model (LLM) that manages stock and marketing campaigns.
• Agentic payment: integrates the entire purchasing journey directly within a chatbot. This raises significant challenges, including fraud management, user mandate definition, and overall market maturity.

The term "agentic" derives from the concept of an agent — a software entity capable of acting autonomously to achieve specific objectives.

How does agentic payment work?

AI-driven purchasing typically follows six steps:

1. Expression of need: the user simply describes a need in natural language.
2. Analysis and identification: the AI agent understands the intent and precisely identifies the requirement.
3. Search and comparison: the agent queries structured real-time data — pricing, stock levels, delivery times, return policies.
4. Decision-making: the AI weighs up options against the user's defined criteria.
5. Validation: depending on the configured level of autonomy, the agent either obtains the customer's approval or acts directly, using a payment solution configured to authorise the agentic payment.
6. Completion: the purchase is finalised using an authorised payment method.

With agentic payment, the AI agent no longer simply assists the consumer — it becomes the buyer. Agentic payments begin well before the transaction itself, when the agent helps the customer articulate their need, reduce complexity, and move towards a decision.

From product search to delegated purchasing

Here are examples of agentic purchase missions assigned to an AI agent:

• "Book the cheapest flight arriving in Bruges before noon tomorrow."
• "Find a pair of black men's trail running shoes in size 9, under €150."
• "Buy the book that won the Prix Goncourt in 2025."
• "Renew my monthly order of household products for delivery next Tuesday."

How to prepare for agentic payment

Agentic payment is currently live in the United States — but it is coming to France and Europe in 2026. Merchants and brands need to start preparing now, rethinking their journeys and strategies to meet the expectations of AI agents.

Here are our recommendations for getting your business AI-purchase-ready, drawn from the findings and best practices already in deployment in the US.

Tip 1: Make your site agentic payment-compatible

You have already built your e-commerce site — content, customer journey, payment process — with your customers and search engine visibility in mind. That is a solid foundation. But from now on, it also needs to work for AI. Product listings, navigation, and — critically — payment tools will all need to be updated to accommodate agents.

If your brand does not feature in the responses served by AI platforms, you will be invisible in a near future where search is agentic. Just as SEO forced websites to become readable by Google, agentic payment demands that your site become intelligible to AI agents.

How can you make your site AI-friendly?

To become agent-ready — enabling AI to purchase on behalf of customers — your website should provide:

✓ High-quality content: ensure your site content is up to date, expertise-driven, and aligned with search intent.

✓ Strong technical accessibility (crawlability): ensure a clean, well-structured site architecture so that bots can explore and index all your content without friction.

✓ Structured and standardised data: use data schemas recognised by AI agents.

✓ Fast and verifiable payment processes: optimise your conversion funnels and checkout for agents.

✓ Transparent, machine-readable policies: structure and clarify your terms of sale, returns, and guarantees.

✓ Clear and unambiguous information: provide clear, comprehensive, and up-to-date product and service information.

Tip 2: Work with partners specialised in agentic payment

Agentic payment is evolving rapidly, with:

• Emerging protocols (UCP, AP2, MCP — discussed below),
• Continuously evolving structured data standards,
• New business models (agent-accessible APIs and AI service monetisation).

In this environment, choosing a payment solution designed for agentic payments is essential.

Payplug is at the forefront of agentic payment developments. We are building our own MCP (Model Context Protocol) server — a standardised protocol that acts as a translator between AI agents and payment systems. This development is part of our broader commitment to anticipating market shifts and delivering more capable solutions. The goal: enabling you to sell directly through artificial intelligence.

Payplug: a partner in Google's agentic payment work

The Payplug team is involved in joint work with Google to develop the Agent Payments Protocol (AP2) — designed to secure and standardise AI-initiated payments. We are helping to lay the foundations for conversational agent purchasing, so we can support you through this transition.

Tip 3: Build a trust framework with your customers

Agentic payment raises legitimate concerns among consumers around the security of payment details, the handling of personal data, consent, and the delegation of purchasing authority.

To reassure your customers:

• Implement highly secure transactions and robust fraud management.
• Be transparent about how data is used.
• Provide granular control options over the permissions granted to agents.
• Communicate clearly about the steps you are taking to secure agentic payments — including your choice of a payment provider with proven agentic expertise.

Tip 4: Integrate agentic payment into an omnichannel strategy

Artificial intelligence is a fully-fledged sales channel in its own right — on a par with a physical point of sale, an online store or social media. To maximise its potential, integrate it into a coherent omnichannel strategy that delivers a seamless, consistent experience for your customers, regardless of the channel they use.

What already exists in the US — and what’s coming to Europe

After a year marked by major announcements and milestones in the United States during 2025, agentic payment is now on the verge of arriving in Europe, and particularly in France.

The United States: the global leader in agentic payment

In the US, AI agents can already search for, select, and purchase products on behalf of customers directly within conversational interfaces.

OpenAI: Instant Checkout & Agentic Commerce Protocol

OpenAI has rolled out Instant Checkout within ChatGPT for US users, enabling purchases to be made directly from a conversation — without leaving the interface — from sellers including Etsy, with Shopify to follow. This in-chat purchasing experience is built on the Agentic Commerce Protocol (ACP), an open standard for integrating payments and the full checkout experience into AI agents.

Google launches UCP: an agentic purchasing protocol built into Gemini

At NRF 2026 (National Retail Federation), Google unveiled a significant new milestone in the evolution of e-commerce: the Universal Commerce Protocol (UCP), an open standard similar to ACP, developed in collaboration with Shopify and Visa. It has been integrated into Gemini (Google's AI) and its AI Mode.

Users can:

• Browse, compare, and purchase products directly within Gemini or Google Search via Buy Now buttons.
• Walmart, Target, Etsy, Wayfair, Shopify and other major retailers are already UCP partners.

This creates a multi-platform ecosystem where AI agents can handle end-to-end transactions — from product discovery to payment completion — without leaving the AI environment. It is designed to work with existing commerce infrastructure and is compatible with the Agent Payments Protocol (AP2) to ensure secure agentic payments.

AP2 vs UCP: what is the difference?

In agentic payment, AP2 enables agents to understand and compare offers, while UCP turns that decision into an actual purchase. For merchants, the choice is not between one or the other — it is about making your offering both comprehensible and purchasable by AI agents.

Amazon: Buy for Me

Amazon launched Buy for Me in April 2025. This AI feature, built into the Amazon app, purchases products on the user's behalf — including from third-party sites if an item is not available directly on Amazon. The agent automatically completes checkout and manages the transaction on the user's behalf.

Shopify: Agentic Commerce

Shopify launched Agentic Commerce in August 2025. The system enables conversational AI to purchase directly from within its own interface, rather than redirecting to an external site. The goal is to allow AI agents to search, compare, add to basket, and complete checkout for products across Shopify-powered stores.

Microsoft Copilot Checkout

Microsoft has extended Copilot with Copilot Checkout (currently live in the US): the AI can now search, compare, select, and complete a purchase within the same interface, with integrations across Stripe, PayPal, Shopify, and more.

Europe: imminent adoption

As of January 2026, agentic commerce is not yet widely deployed in France or Europe — but several clear signals point to an imminent arrival.

Why is it not live in Europe yet?

The rise of agentic payment raises major strategic questions around payment security, authentication, consent management, and liability. Europe is currently assessing the regulatory implications of autonomous AI payments, including KYC and anti-fraud requirements. Major technology platforms are also adapting their services to European market requirements — GDPR, PSD2, PSD3 directives, and more.

Open standards (ACP & UCP) are accelerating Europe's readiness
OpenAI's Agentic Commerce Protocol and the Universal Commerce Protocol are designed as open standards. Google has already confirmed that its features will be rolled out internationally following the US launch, signalling a planned European deployment as soon as regulation and infrastructure allow.

Carrefour has already announced native integration with Google's full ecosystem through the adoption of the UCP standard.

In summary

Agentic payment represents a fundamental shift in how people shop — and how businesses sell. In the near future, your customers will delegate part of their purchasing decisions to AI. This will inevitably raise critical questions around adapting authentication processes and fraud prevention.

Payplug is here to help you prepare your business for this new era of commerce. Our goal is to build the capability to process AI-initiated payments — adapting our systems to recognise and execute these transactions. The result: enabling users to have AI manage complex or recurring purchases autonomously, within conditions defined in advance, and with no compromise on security standards.
