E-commerce is entering a new era where customers discover and purchase products directly through conversational AI. With ChatGPT’s new Instant Checkout feature, millions of shoppers can now buy from your WooCommerce store without ever leaving their chat conversation. This comprehensive guide walks you through the complete merchant account registration process and how to integrate your website with ChatGPT’s shopping cart using the Agentic Commerce Protocol.
What Is ChatGPT Instant Checkout?
ChatGPT Instant Checkout is OpenAI’s revolutionary shopping feature that transforms ChatGPT from a search assistant into a complete commerce platform. Launched in late 2024, this feature allows U.S. customers using ChatGPT Free, Plus, and Pro plans to discover products, compare options, and complete purchases entirely within the chat interface.
When someone asks ChatGPT a shopping-related question like “best running shoes under $100” or “unique gifts for coffee lovers,” the AI displays relevant products from across the web. If your products support Instant Checkout, customers see a “Buy” button that enables them to complete their purchase without leaving ChatGPT—creating a frictionless shopping experience that dramatically shortens the path from discovery to conversion.
Key Benefits for WooCommerce Merchants
- Access to Millions of Shoppers: Tap into ChatGPT’s massive user base of over 100 million active users
- Reduced Cart Abandonment: Customers complete purchases in-chat without navigating to multiple websites
- Organic Product Discovery: No advertising costs—products appear based on relevance to user queries
- You Remain in Control: Keep full control over pricing, inventory, payments, fulfillment, and customer relationships
- Future-Ready Platform: Position your store at the forefront of AI-powered commerce before it becomes mainstream
Understanding the Agentic Commerce Protocol (ACP)
At the heart of ChatGPT’s Instant Checkout is the Agentic Commerce Protocol (ACP)—an open-source standard co-developed by OpenAI and Stripe that enables AI agents to facilitate purchases between buyers and merchants.
Think of ACP as a universal language that allows ChatGPT to communicate with your WooCommerce store. It handles everything from product discovery to checkout session creation, payment processing, and order confirmation—all while keeping you as the merchant of record.
Why ACP Matters for Your Business
- Open Standard: Not limited to one platform—works across multiple e-commerce systems
- Payment Processor Agnostic: Continue using your existing payment provider through Stripe’s Shared Payment Token API
- Minimal Integration: No need to rebuild your backend systems
- PCI Compliant: Secure tokenization ensures sensitive payment data is handled safely
- Scalable: Designed to evolve with agentic commerce as AI shopping becomes more sophisticated
Merchant Account Registration: Step-by-Step Process
Getting your WooCommerce store approved for ChatGPT Instant Checkout involves several key steps. Here’s the complete registration process:
Step 1: Apply for ACP Merchant Access
Your journey begins with the official OpenAI merchant application:
- Visit https://chatgpt.com/merchants
- Complete the merchant application form with your business details
- Provide information about your store, product categories, and country of operation
- Submit your application for review
Important Note: While Instant Checkout is currently live only for U.S. merchants and U.S. customers, OpenAI accepts applications from merchants worldwide. The platform plans to expand to additional regions in 2025, so applying now positions you for early access when your region becomes available.
Step 2: Get Approved and Receive Your OpenAI API Key
OpenAI reviews merchant applications on a rolling basis. Priority is given to:
- Merchants with established e-commerce operations
- Stores with quality product catalogs and clear inventory management
- Businesses that can demonstrate compliance with consumer protection standards
- Merchants using platforms like Shopify, WooCommerce, Magento, or other established e-commerce systems
Once approved, you’ll receive access to the OpenAI ACP dashboard where you can obtain your API credentials.
Step 3: Set Up Your Stripe Integration
Stripe powers the payment infrastructure for ChatGPT Instant Checkout. Here’s what you need:
- Create or log into your Stripe account at https://dashboard.stripe.com
- Navigate to Developers > API Keys
- Copy your Publishable Key and Secret Key
- Store these credentials securely—you’ll need them for your WordPress plugin configuration
Good News: If you’re already using a different payment processor, you don’t need to switch. ACP supports integration with other processors through Stripe’s Shared Payment Token API or the open Delegated Payments Specification.
Step 4: Install the WooCommerce ACP Plugin
For WooCommerce stores, the easiest way to implement the Agentic Commerce Protocol is through the Instant Checkout via ACP Agentic Commerce for WooCommerce plugin, developed by Web Vijayi.
Plugin Installation Methods:
Method 1: Direct WordPress Installation
- Log into your WordPress admin dashboard
- Navigate to Plugins > Add New
- Search for “Instant Checkout ACP”
- Click Install Now, then Activate
Method 2: Manual Installation
- Download the plugin from https://wordpress.org/plugins/instant-checkout-via-acp-agentic-commerce-for-woocommerce/
- Upload the plugin files to
/wp-content/plugins/instant-checkout-via-acp-agentic-commerce-for-woocommerce - Activate the plugin through the WordPress plugins screen
Step 5: Configure Plugin Settings
After activation, configure the plugin to connect your store with ChatGPT:
- Go to WooCommerce > AI Checkout in your WordPress admin menu
- Enter your OpenAI API Key from the ACP dashboard
- Enter your Stripe Publishable Key
- Enter your Stripe Secret Key
- Enable Test Mode for initial testing (orders will be marked clearly as test transactions)
- Save your settings
Step 6: Enable Products for ChatGPT Checkout
The plugin gives you granular control over which products appear in ChatGPT:
Per-Product Control:
- Edit any product in WooCommerce
- Look for the “ChatGPT Checkout” meta box
- Check the box to enable the product for Instant Checkout
- Update the product
Bulk Actions:
- Go to Products > All Products
- Select multiple products using checkboxes
- Choose “Enable ChatGPT Checkout” or “Disable ChatGPT Checkout” from bulk actions
- Click Apply
Step 7: Prepare Your Product Feed
The plugin automatically generates a machine-readable product feed at:
https://yourdomain.com/wp-json/icvaac/v1/product-feed
This feed contains all products you’ve enabled for ChatGPT checkout, formatted according to OpenAI’s specifications. The feed updates automatically when you add, modify, or remove products.
Step 8: Configure Your Robots.txt File
To ensure OpenAI’s crawlers can access your product feed, update your robots.txt file:
User-agent: GPTBot
Allow: /
User-agent: ChatGPT-User
Allow: /
User-agent: OAI-SearchBot
Allow: /
The plugin includes built-in instructions for this setup in the settings panel.
Step 9: Submit Your Product Feed to OpenAI
- Log into your OpenAI Merchant Portal
- Navigate to the Product Feed section
- Enter your product feed URL:
https://yourdomain.com/wp-json/icvaac/v1/product-feed - Submit the feed for indexing
OpenAI will crawl your feed regularly (up to every 15 minutes) to keep your product information current in ChatGPT.
Step 10: Test Your Integration
Before going live, thoroughly test your setup:
- Keep Test Mode enabled in plugin settings
- Search for your products in ChatGPT
- Complete a test purchase through the Instant Checkout flow
- Verify that test orders appear in your WooCommerce orders with clear test indicators
- Confirm payment processing works correctly
- Test order acceptance and fulfillment workflows
Once testing is complete and you’re satisfied with the integration, disable Test Mode to start accepting real customer orders.
Optimizing Your Products for ChatGPT Discovery
Getting approved is just the beginning. To maximize visibility and conversions in ChatGPT, optimize your product data:
Product Information Best Practices
- Clear, Descriptive Titles: Use natural language that answers what the product is and who it’s for
- Rich Descriptions: Include use cases, materials, dimensions, and benefits—not just features
- High-Quality Images: Upload clear, professional product photos with multiple angles
- Accurate Pricing: Keep prices current; ChatGPT surfaces competitive options
- Complete Specifications: Add GTINs, brand names, sizes, colors, and variants
- Stock Availability: Maintain accurate inventory levels to avoid showing out-of-stock items
Context Is King
ChatGPT Shopping is persona-driven. When someone asks “best yoga mat for beginners with knee pain,” ChatGPT needs contextual information to match your product to that specific need.
Enhance your product pages with:
- Who the product is designed for (beginners, professionals, specific demographics)
- What problems it solves
- How it compares to alternatives
- Use case scenarios
- Material details and care instructions
Leverage Third-Party Validation
Products featured in authoritative reviews, buying guides, and editorial content from trusted publications appear more frequently in ChatGPT suggestions. Consider:
- Seeking product reviews from industry publications
- Getting featured in “best of” roundups
- Encouraging customer reviews on your site
- Building relationships with content creators in your niche
How ChatGPT Ranks Merchants
Understanding ChatGPT’s ranking factors helps you compete effectively:
Product Results Ranking
Initial product recommendations are based purely on relevance to the user’s query. ChatGPT considers:
- Query match with product titles and descriptions
- User context (conversation history, preferences, location)
- Product availability
- Third-party validation signals
Merchant Ranking (When Multiple Sellers Offer the Same Product)
When multiple merchants sell an identical product, ChatGPT ranks merchants based on:
- Availability: In-stock products are prioritized
- Price: Competitive pricing improves position
- Quality: Review ratings and seller reputation
- Primary Seller Status: Manufacturers and authorized dealers get preference
- Instant Checkout Enabled: Having the buy button active provides a ranking advantage
Important: Enabling Instant Checkout doesn’t boost your product in initial search results, but it does improve your merchant ranking when users have already decided on a specific product.
Merchant Fees and Pricing Structure
ChatGPT Instant Checkout operates on a performance-based model:
- Product Discovery: Free—no cost to have your products appear in ChatGPT results
- Transaction Fee: Small percentage fee on completed purchases only
- No Subscription Costs: Pay only when you make sales
- Refund Policy: Fees are refunded if you issue a refund to the customer
- Customer Pricing: Instant Checkout is free for buyers and doesn’t affect product prices
Common Integration Challenges and Solutions
Challenge: Products Not Appearing in ChatGPT
Solutions:
- Verify your product feed URL is correctly submitted to OpenAI
- Check that products are enabled for ChatGPT checkout in WooCommerce
- Ensure your robots.txt allows OpenAI bots
- Wait 24-48 hours after initial feed submission for indexing
- Verify feed URL is accessible and returning valid data

Challenge: Order Not Syncing to WooCommerce
Solutions:
- Check plugin version is up to date
- Review WordPress error logs for API connection issues
- Verify webhook endpoints are configured correctly

Frequently Asked Questions
Do I need to be on Shopify or Etsy to use ChatGPT Instant Checkout?
No. While Shopify and Etsy were launch partners, the Agentic Commerce Protocol is an open standard that works with any e-commerce platform, including WooCommerce, Magento, and custom-built stores.
Can I use my existing payment processor?
Yes. Although Stripe co-developed ACP, the protocol supports integration with other payment processors through Stripe’s Shared Payment Token API or the Delegated Payments Specification without requiring you to switch processors.
How much does it cost to list products in ChatGPT?
Product discovery is free. You only pay a small transaction fee on completed purchases. There are no listing fees, subscription costs, or upfront charges.
Is ChatGPT Instant Checkout available outside the United States?
Currently, Instant Checkout is available only for U.S. merchants and U.S. customers. However, merchants worldwide can apply now to position themselves for early access when OpenAI expands to new regions in 2025.
Will ChatGPT favor products that pay more in fees?
No. Product recommendations are ranked based on relevance to user queries, not on fees paid. ChatGPT does not operate on a paid placement model—all results are organic.
What happens to my customer data?
You remain the merchant of record with full ownership of customer relationships. ChatGPT securely passes only the information necessary to complete the transaction. OpenAI asks merchants not to auto-subscribe customers from ChatGPT orders to marketing emails.
Can I control which products appear in ChatGPT?
Yes. The Instant Checkout ACP plugin allows per-product control. You can enable or disable ChatGPT checkout for individual products or use bulk actions to manage multiple products at once.
How quickly do product updates reflect in ChatGPT?
OpenAI crawls product feeds up to every 15 minutes, so changes to pricing, inventory, or product details should appear relatively quickly. However, some delay may occur during high-traffic periods.
