E-commerce
August 26, 2026
Are you wondering how to adapt your store to let artificial intelligence make purchases on your behalf? This is the central question of the agentic commerce era, where buying behavior is radically transformed without direct human intervention. To succeed in this transition, you must modify three fundamental aspects of your infrastructure: make your catalogs immediately readable by a machine, configure filters to identify legitimate buyer agents from malicious bots, and establish a payment protocol allowing delegated authorization.
This evolution does not rely on marketing or the visual interface, but on the very structure of your data and security. Success depends on the coordination between your product data pipeline, your web application firewall, and your payment flow. So, what are the three critical changes to make? On the agenda:
Why is a machine-readable catalog the essential foundation?
How to distinguish a buyer agent from a malicious scraper?
What mechanism permits third-party authorized payments?
How are Google and Adyen preparing the infrastructure in 2026?
What are the consequences of a partial change on conversion?
Let's get started.
Summary
Why is a machine-readable catalog the essential foundation?
The buying agent cannot navigate your site like a human. It does not execute any JavaScript scripts and it does not see pages dynamically assembled in a web browser. If your product data is only encapsulated in rendered HTML code or hidden in images, the agent remains blind to your offer. For it, this information does not exist.
The major challenge lies in the need to provide a structural and immediately readable source of truth. Your product feeds and structured data (such as Schema.org Product and Offer tags) become the product experience itself, rather than a mere copy of your storefront. The agent needs to compare prices, stock availability, variants (size, color), as well as shipping and return conditions without ever displaying the page.
If this data is missing or fragmented in your XML or delimited files, the agent cannot make an accurate selection. Furthermore, data freshness is critical: a feed updated once a night risks generating orders at an outdated price the following morning, as the agent will not see the recent changes. Completeness of attributes then becomes your new merchandising surface for AI.
A single missing piece of data can silently exclude your product from the agent's search filters, without any error message or opportunity to compete. To learn more about structuring your data for SEO and agents, see our article on What is Google Shopping for e-commerce?.

How to distinguish a buyer agent from a malicious scraper?
Currently, the distinction between a legitimate AI agent and a data scraper is one of the most complex technical challenges. Classical bot mitigation systems are designed to block suspicious requests based on rapid request rates, the absence of human interactions such as mouse movement, and low-reputation IP addresses.
The problem is that these signals perfectly match the behavior of a legitimate buyer agent. The agent makes numerous requests quickly, runs in headless mode without physical human interactions, and often originates from cloud IP address ranges considered suspicious by standard reputation systems.
There are four current identification methods. The first consists of self-declaring identity in the User-Agent, but anyone can spoof this. The second relies on reverse DNS verification of IP ranges, which binds the agent to a fixed infrastructure. The third uses a cryptographic signature that the merchant verifies against a public key, thereby proving the origin of the request.
Finally, authorization by commercial agreement allows specific partners to be whitelisted. Relying solely on the self-declared identity creates a dangerous asymmetry, as opening an unsecure route exposes your brand to price scraping rather than a failed transaction. To understand how to secure your exchanges while remaining open to new channels, read our study on What is an order management system really used for in e-commerce?.
What is the mechanism for authorizing payments on behalf of third parties?
The third critical change concerns the transaction signature. An AI agent does not have its own physical credit card and does not have a cookie session inherited from a previous human interaction. The agent therefore attempts to make a payment with a delegated authorization from the cardholder, who is not physically present.
The traditional payment flow requires direct consumer intervention to validate each step. In agentic commerce, this process must evolve to accept authorization originating from a third party (the agent) acting on behalf of the legitimate customer. Without this capability, even if the agent finds the right product and manages to bypass security filters, it will abandon the purchase at the moment of finalization.
This requires a redesign of authentication and validation protocols. The infrastructure must recognize a valid signature issued by an authorized third party, verifying that the cardholder has indeed consented to this delegation of authority. This is a matter of contractual and technical trust between the merchant, the payment provider, and the agent.
Platforms must therefore evolve to accept payment flows that do not rely on the physical presence of the cardholder, but on a solid legal and technical framework. This is the final link in the chain that allows a comparison to be transformed into an actual sale.
How are Google and Adyen preparing the infrastructure in 2026?
The market has already begun to react to this infrastructure need. In January 2026, Google released specific tools to help retailers prepare for the era of AI agent shopping. This announcement does not prove that a strict requirement is immediately imposed on everyone, but it clearly indicates where the largest platform expects this work to be done.
Similarly, in June 2026, Adyen launched its "Adyen Agentic" solution. These moves show that industry leaders do not see this as a marginal option, but as an upcoming, unavoidable standard. The goal is to provide the technical framework to allow agents to read catalogs and process delegated payments.
Media coverage of these launches highlights that there are now several competing protocols for agent-to-merchant purchasing. The question is no longer whether platforms will support this type of purchasing, but how they will organize themselves to support these flows. To delve deeper into the context of these technological developments and their impact on platform choices, read our analysis on Which platform to choose for selling digital products?.
What are the consequences of a partial change on conversion?
It is crucial to understand that applying these three changes individually without combining them leads to silent and costly failures. If you made your catalog readable but blocked agents at the firewall, they would never be able to access your products.
Conversely, if you open the door to the agent with good data readability but without a delegated checkout flow, the agent will be able to accurately compare and select a product, only to ultimately abandon the transaction at the payment stage. Conversion will fail not because the product is uninteresting, but because the finalization mechanism does not exist.
Similarly, if you set up the checkout flow but your product data is incomplete or outdated, the agent will not be able to make the final selection. Each component depends on the other two to form a complete, functional loop. The agentic purchasing ecosystem is an interconnected system where every link must be robust.
This means you cannot compromise on any of the three pillars at the expense of the others. The success of agentic commerce relies on the simultaneity and consistency of these three technical modifications. This is why an integrated approach is essential for your growth strategy.
Why doesn't marketing control these technical changes?
It is essential to realize that these three fundamental pillars are not the responsibility of the marketing department. They are inherent to the platform itself and require interventions at the technical infrastructure level.
The first pillar, the machine-readable catalog, depends on your product data pipeline and your database structure. The second, agent distinction, depends on your web application firewall (WAF) and your security systems. The third, delegated payment, depends entirely on your payment stack and your order management system.
The marketing department cannot modify these elements through simple visual or textual adjustments on the online store. This requires direct collaboration with technical teams, developers, and payment service providers. Ignoring this technical dimension is like trying to build a road without solid foundations.
To scale your brand, you must therefore integrate these technical considerations from the very beginning of your expansion strategy. Understanding who holds the key to each brick is the first step toward successful adoption.

How do data specifications become the new merchandising?
In the era of agentic commerce, the quality and completeness of product metadata become the primary selection criteria. The agent filters your products based on precise criteria: price, availability, specific variations, and logistics terms.
If you leave a field blank or if your data is not accessible via standard formats (such as XML feeds or structured data), the agent silently excludes your product from search results. It cannot guess your brand's intent if it does not find the explicit data it expects.
This radically transforms the discipline of merchandising. It is no longer just a question of attractive images or persuasive copy, but of technical rigor in publishing product attributes. Every missing field is a lost sales opportunity without you ever knowing it.
Every attribute must be treated as a potential entry point for the agent. Data completeness thus becomes a direct competitive advantage, allowing your products to remain visible in automated comparisons.

What are the risks related to data freshness for the buyer agent?
The frequency with which your catalogs are updated is a critical factor for financial and operational risk. An AI agent relies on the data it receives at the moment of its request to make an immediate purchasing decision.
If your product feed is updated daily or weekly, you risk offering prices that no longer reflect market reality or non-existent stock. An agent could validate an order at an obsolete price or order a product that has been out of stock since last night.
This leads not only to transaction errors and operational costs, but also to a loss of trust from the end-user and the agent itself. Automation requires near real-time synchronization between your stock, your prices, and the data exposed to the AI.
To minimize these risks, it is imperative to review the frequency of your updates and ensure minimal latency between a stock/price change and its propagation to agent channels. This is a sine qua non condition for operating in this new paradigm.
Why are signing protocols the key to trust?
The cryptographic signature system represents the most robust method for identifying a legitimate buying agent. Unlike the simple declaration of identity in the User-Agent, which can easily be copied by any malicious script, the signature verifies a unique public key.
This mechanism allows the merchant to guarantee that the request indeed comes from the certified agent they have authorized. This solves the fundamental problem of trust and scalability: you can open your catalog to multiple agents without the risk of being attacked by masked scrapers.
However, this requires an exchange of information and a prior configuration between the merchant and each agent. It is a process that relies on a clear contractual relationship and a technical infrastructure capable of validating these signatures in real time.
Without this security layer, opening up to agentic commerce exposes your business model to the risk of sensitive data theft or unfair competition. To better understand security protocols in this context, we invite you to explore Does Google offer an e-commerce platform?.
How agent feedback shapes the offering
Interactions with buying agents can generate a wealth of valuable data on how your products are perceived and compared. These agents can provide you with direct feedback on what works or doesn't work in your offering.
By analyzing why an agent chose or rejected a product, you can identify gaps in your metadata or opportunities for improvement that human users don't always report. It's a unique feedback loop that allows you to continuously optimize your catalog for algorithms.
However, it should be noted that not all behavior data is accessible or analyzable today. The precise measurement of results is complex and often limited by the lack of standardized tools at this stage of market evolution.
To exploit these opportunities, you must implement sensor systems capable of collecting and analyzing these specific interactions. It is a powerful growth lever for brands that know how to listen to their invisible "customers".

What is the checklist before deploying your agentic strategy?
Before opening your store to purchasing agents, make sure you have validated the three fundamental pillars: complete readability of your catalogs via standardized feeds and up-to-date structured data, a security policy capable of distinguishing and authorizing legitimate agents, and a payment system ready to accept secure delegated authorizations.
Also, check the freshness of your data: it must be synchronized in real-time to avoid pricing or stock errors. Finally, clearly define who will be authorized to access your catalog and implement robust cryptographic signature protocols.
In brief
Agentic commerce relies on machine readability, secure identification, and delegated payment. It is a profound technical transformation that does not depend on visual marketing but on the structure of your data and your security.
