A quick look at which AI assistants handle purchases on WooCommerce when AI‑native payment systems like PayLayer are in place:
These assistants don’t buy things on their own. They act as helpers, suggest options, then complete the purchase only after the user gives clear permission inside the AI platform. Traditional checkout pages with forms or CAPTCHAs won’t work here, and these agents need merchants to offer programmatic payment interfaces, usually through plugins like PayLayer.
Two pieces must line up for smooth ordering: the assistant must support automated buying workflows, and the merchant must expose machine‑readable product data and accept payments through compatible tools.
This article focuses on WooCommerce stores, and the same approach applies anywhere online shops expose smart payment endpoints.
How AI moves from recommendations to real transactions
AI agents suggest products based on what a person is likely to want or need. They surface items, styles, and deals, but they don’t commit to anything. Transactions are different. Those reserve inventory, place an order under the user’s account, and process payment to finish the purchase.
No assistant places an order without a clear go-ahead from the user. A request like, “Buy the Nike Air Zoom Pegasus 41 in size 10, under $140, ship to my default address,” is a direct command that shows intent and permission. If that approval isn’t given inside the AI platform, the system doesn’t proceed.
Here’s how the purchase flow works:
- Discover a product through site search or a catalog API.
- Verify price and availability to confirm it’s still valid.
- Get user authorization inside the AI service before proceeding.
- Send a programmatic payment call to the merchant’s system.
- Confirm the purchase to the user with order details.
Real-world issues come up. Stock changes fast. People switch sizes or colors. The assistant adapts to those changes. Taxes and shipping fees are calculated upfront so checkout totals are clear. Final prices are confirmed before any card is charged.
After an order is placed, the assistant shares an order ID, itemized total, merchant name, and a timestamp for every transaction. People can review past orders or flag a problem if something looks wrong.
Why human checkout blocks agents and how to fix it on WooCommerce
Most WooCommerce checkouts assume a person is on the site. They rely on browser sessions that track form progress, CAPTCHAs that block bots, and scripts that wait for clicks and typing. Works fine when someone’s at a keyboard, but it blocks AI agents trying to buy without a browser.
Agents don’t fill forms or solve CAPTCHAs like humans. They also aren’t allowed to store or replay card data on merchant sites because of PCI rules and platform policies. Payment details live inside the assistant’s wallet or account, away from the merchant. Safer for everyone.
For an agent to place an order cleanly, a standard product page isn’t enough:
- Machine-readable endpoints with SKU numbers, prices, stock levels, and variants
- A secure payment endpoint that accepts signed requests to prove who’s calling
- Real-time inventory checks so orders don’t fail on out‑of‑stock items
- Confirmation steps to lock in final prices with taxes and shipping
PayLayer solves this gap. It’s a WordPress plugin that exposes pricing and purchase APIs for AI assistants while leaving the storefront unchanged for human shoppers. Merchants keep their current theme and flow. Agents get programmatic access in the background.
Security sits at the center. PayLayer verifies each signed request before it creates a WooCommerce order. It confirms prices and stock, then settles payment through an authorized charge handled by the AI platform, not the merchant’s server. No card storage at the store level. Fraud risk drops because each transaction gets checked end to end between known parties.
PayLayer for WordPress enables programmatic pricing and payments
PayLayer sits next to WooCommerce and connects AI assistants to the store’s backend. It publishes product data in a machine-readable format – SKU numbers, prices, currency, tax classes, shipping options – through a signed API. AI agents get direct access to store data without changing the normal shopping flow.
When an AI assistant needs availability or pricing, it requests offers by product URL or SKU. The store returns clean JSON with everything required, including the final price with taxes and shipping for the destination. Agents receive exact totals upfront, no guesswork.
The payment flow runs in reverse compared to a standard checkout. The AI platform charges the user first, either from a wallet or a saved payment method, then sends PayLayer a signed remittance as proof of payment. PayLayer uses that confirmation to create a WooCommerce order marked paid immediately. No waiting for manual approval, no extra steps.
For shoppers on the website, nothing looks different. The usual theme, cart, and checkout stay in place, because PayLayer’s endpoints don’t respond to normal browser traffic. SEO stays stable, and Core Web Vitals stay steady, since these calls happen in the background.
Merchants set the rules for PayLayer:
- Set rate limits to prevent overload from high agent traffic
- Require minimum authorization scopes so only trusted agents can purchase
- Log every purchase with notes on which agent acted, the AI platform name, and the exact user-confirmed intent string
- Keep detailed records for audits or troubleshooting
Who can buy today with AI‑native payments: ChatGPT, Claude, Gemini, Grok, and DeepSeek
ChatGPT can shop on WooCommerce stores through PayLayer’s programmatic payments. It looks up products by SKU or URL, checks live price and stock, then asks for clear permission before anything happens. After approval, it completes the purchase in the background and returns a Woo order ID with a full confirmation. Payments stay inside ChatGPT’s secure flow, not in traditional checkout forms.
Claude works as an agent tool that calls PayLayer endpoints to pull product offers straight from WooCommerce. It asks for explicit approval before any charge, skips human checkout pages, then runs the payment and shares the order details. No form fields, no redirects.
Gemini by Google acts as a middle layer between shoppers and WooCommerce when PayLayer exposes machine-readable pricing and payment APIs. It shows a final price with taxes and shipping, asks for consent, then processes the charge in its own secure system. Users get an order summary without a browser-based checkout.
Grok finalizes orders on WooCommerce stores that use PayLayer plugins by calling pricing and purchase APIs. It finds items through product data endpoints, asks for direct authorization inside its interface, then completes the buy. It records merchant name, item, and total cost, and shares these details for easy review.
DeepSeek uses the same API endpoints to place orders once users approve each step inside its environment. Funds move from the AI platform’s wallet or saved payment methods to the merchant after PayLayer verifies the payment. Card data stays off merchant servers, and users get quick confirmation once the order goes through.
Example purchase flow and how to test it safely on your store
Picture a shopper telling an AI assistant, “Buy the Nike Air Zoom Pegasus 41, size 10, under $140, ship to my default address.” The assistant understands the request and calls the WooCommerce store’s PayLayer product endpoint. It pulls real-time details, including variant availability and the exact price with taxes and shipping for that address. No guesswork. With the full total in hand, the assistant asks for a quick confirmation: here’s the item and the final price.
Once approved inside the AI platform, payment runs securely there, not on the merchant’s site. The AI service charges the user’s account or wallet, then sends a signed purchase request to PayLayer. The signature works as a digital handshake that proves authenticity and intent.
PayLayer validates the signature, reserves inventory so those shoes don’t get taken, and creates an official WooCommerce order with line items, tax details, and the chosen shipping method. It returns an order ID and a receipt URL to the assistant.
The assistant shares the results right away: merchant name, order number, itemized total with all fees, and an estimated delivery time. Funds settle to the merchant as usual while fulfillment runs through normal WooCommerce workflows.
Merchants who want their stores ready for AI-driven purchases with programmatic payments through PayLayer should test in a staging environment. Verify product endpoints expose accurate SKU-level data with live stock counts and final prices that include taxes and shipping based on the address. Confirm the payment API accepts signed requests and logs every transaction detail for audits.
Keep thorough records of each test. Note any gaps between expected and returned data or any issues during authorization. Fix these before going live to reduce errors when customers order through assistants instead of browsers.
