Agentic Commerce Protocol: The Complete 2025 Guide to Selling Inside ChatGPT & Claude

The Future of Shopping Just Arrived—And It Doesn't Require a Website

Imagine a customer opens ChatGPT, describes what they're looking for, and seconds later—without ever visiting your store—they've purchased from you. No browsing your website. No navigating to checkout. Just an instant transaction inside an AI assistant.

This isn't science fiction. This is the Agentic Commerce Protocol (ACP), and it's reshaping how merchants sell online.

If you're running an e-commerce store, a service business, or even a simple product catalog, ACP represents a fundamental shift in how customers discover and buy from you. But unlike past e-commerce revolutions, you don't need a fancy website or a dedicated app store to participate.

This guide explains what ACP is, why it matters for your business, and how to get started—without technical jargon or overwhelming complexity.

What Is the Agentic Commerce Protocol?

The Agentic Commerce Protocol is an open standard that allows AI agents (like ChatGPT, Claude, or custom business assistants) to complete purchases directly on behalf of customers—without human intervention in the transaction itself.

Think of it this way:

Traditional e-commerce: Customer visits your website → browses products → adds items to cart → enters payment details → completes checkout.

Agentic commerce: Customer tells an AI agent what they want → the agent finds your product → confirms the order with the customer → the purchase completes automatically.

ACP is the "language" that tells your online store, "Hey, an AI agent is trying to buy something. Here's the customer's intent, here's what they want, and here's permission to complete the transaction."

It's not a marketplace. It's not a new platform. It's a protocol—a set of rules and standards—that lets AI assistants talk to your store in a way that's secure, fast, and reliable.

Why Should You Care? Three Reasons ACP Matters Right Now

1. You Reach Customers Inside the Tools They Already Use Daily

Your customers are already spending hours in ChatGPT, Claude, or other AI assistants. With ACP, you don't need to fight for their attention on Google or social media. Your products become discoverable where they already are.

The numbers tell the story: ChatGPT alone has 700 million weekly active users as of 2025. Research shows that 2.1% of ChatGPT conversations involve purchasable products, translating to approximately 75.6 million weekly shopping conversations.

Imagine a potential customer in ChatGPT asking, "Find me a sustainable water bottle under $30." With ACP-enabled stores, that agent can search merchant networks, find your product, confirm the purchase with the customer, and complete the transaction—all within the chat.

Consumer adoption is accelerating: 60% of U.S. consumers expect to use AI shopping agents within the next year, and for specific categories like flights and hotels, adoption intent reaches 70%.

2. Checkout Friction Disappears

The biggest reason e-commerce carts are abandoned? Checkout is too complicated. Long forms. Payment details. Shipping options. Account creation.

The data is sobering: the average cart abandonment rate across e-commerce is 70.22%, with mobile abandonment reaching 85.65%. This represents approximately $4 trillion worth of products left in abandoned carts every year.

With ACP, the AI agent handles all of that. The customer simply confirms they want to buy, and the order goes through. Instant checkout inside a conversation.

Early data shows dramatic improvements. While traditional e-commerce conversion rates hover around 2-3%, conversational commerce powered by AI agents is seeing conversion improvements of 3x or more. Companies using AI-powered conversational commerce report up to 10x increases in conversion rates.

3. Your Existing Store Works—No Rebuild Needed

You don't need to rebuild your entire e-commerce stack or switch platforms. If you have a product catalog (on any platform—Shopify, WooCommerce, custom CMS, or even a spreadsheet), you can make it "agent-ready" by exposing that catalog through an ACP endpoint.

ACP is a layer on top of what you already have. The protocol works with any commerce backend and payments infrastructure. You maintain your customer relationships as the merchant of record, retaining control over which products can be sold, how they're presented, how transactions are processed, and how orders are fulfilled.

Major payment processors have already adopted the standard. In October 2025, PayPal announced its partnership with OpenAI to power Instant Checkout using ACP. Other industry leaders backing the protocol include Mastercard, American Express, Adobe, and Alibaba.

How Does ACP Actually Work? The Basic Flow

Here's what happens behind the scenes when an AI agent buys from your store:

Step 1: Discovery

A customer asks an AI assistant for a product. The assistant searches among ACP-enabled merchants to find matches.

Unlike traditional search results with pages of options, ChatGPT surfaces three to five highly curated product recommendations ranked by relevance. There's no pagination—just the AI's top picks.

Step 2: Catalog Query

The AI agent accesses your product feed through your ACP endpoint. It retrieves pricing, availability, descriptions, and variants—just like checking your website, but programmatically.

ChatGPT's ranking algorithm considers factors like availability, price, quality, whether a merchant is the primary seller, and critically, whether Instant Checkout is enabled.

Step 3: Intent Confirmation

The AI agent confirms with the customer: "I found [product] for [price]. Should I complete this purchase?"

Product recommendations on these platforms are organic and unsponsored, with visibility dependent purely on relevance to the user.

Step 4: Delegated Payment

Once confirmed, the AI agent uses a delegated payment method to complete the transaction. This is where payment providers (like Stripe, PayPal, or similar) step in to securely process the charge without exposing sensitive payment info to the AI system.

The protocol uses cryptographically signed mandates to ensure trust and provide verifiable, auditable processes.

Step 5: Order Placement

Your store receives the order in your normal fulfillment system. From your perspective, it looks like any other sale—you process it, ship it, and keep the margin.

Step 6: Confirmation

The customer receives an order confirmation, tracking info, and support channels—just like a normal online purchase.

Throughout the entire transaction, the merchant remains visible and identifiable.

Anyone Without a Website Yet

One of the most powerful aspects of ACP: you don't need a website to sell. You just need a product feed. ACP essentially becomes your storefront inside AI assistants.

The Three Key Benefits for Your Bottom Line

1. Lower Customer Acquisition Cost

Instead of paying for Google Ads, Facebook ads, or email campaigns to bring traffic to your site, your products are discoverable inside AI assistants where purchase intent is already high. The customer asks for what they want, and the agent finds you.

Data shows ChatGPT is already driving significant referral traffic to major retailers: 20% of Walmart's referral traffic, more than 20% of Etsy's referral clicks, 15% of Target's referral traffic, and 10% of eBay's incoming traffic.

2. Reduced Cart Abandonment

No checkout friction = fewer abandoned carts. While traditional e-commerce sees abandonment rates of 70-85%, conversational commerce dramatically reduces this friction.

Companies using AI-powered conversational tools report 15-20% reductions in cart abandonment rates. The elimination of form fills, account creation requirements, and multi-step checkout processes removes the primary causes of abandonment.

3. Access to New Customer Segments

Customers who might never find you through traditional channels—because they don't use search engines the same way, or they live in underserved markets—can now discover you through AI. Your addressable market expands.

The conversational commerce market is projected to surge from $8.8 billion in 2025 to over $32.6 billion by 2035. By 2025, AI is projected to power 95% of all customer interactions.

What Do You Need to Get Started?

The good news: the barrier to entry is low.

Minimum Requirements:

A product catalog or data (prices, descriptions, images, availability)
A business entity and payment processing (so you can receive orders and payments)
An ACP integration or endpoint (we'll cover this below)
A fulfillment process (how you'll actually deliver the product or service)

That's it. You don't need:

A fancy website
An app
A tech team
Custom development (in most cases)

Getting Connected to ACP:

There are a few paths:

Option 1: Use a Platform That Already Supports ACP

Some e-commerce platforms are integrating ACP support natively. Shopify and Etsy merchants can already enable Instant Checkout in ChatGPT. If you're on one of these platforms, ACP might be as simple as flipping a switch in your settings.

Option 2: Use an ACP Enabler Service

Companies like EasyACP make it simple for non-technical merchants to expose their catalog to agentic commerce without building API endpoints themselves.

Option 3: Build It Yourself (For Developers)

If your store is custom-built, you or your developer can create an ACP-compliant endpoint that exposes your product data. This typically takes a day or two of development work.

Common Questions Merchants Ask

Q: Is this secure? Can an AI agent really charge my customers?

A: Yes, it's secure. ACP uses delegated payment methods that require explicit customer confirmation at every step. The customer always approves the transaction before it completes. Payment processors (Stripe, PayPal, etc.) handle the sensitive payment data—the AI never sees credit card numbers.

Q: What if a customer wants to return something they bought through ACP?

A: You handle returns exactly as you would for any online purchase. ACP doesn't change your return policy or fulfillment process—it just changes how the order is placed.

Q: Will this hurt my profit margins?

A: No. You still set your prices. You still keep your margins. Payment processor fees are similar to Stripe or other standard processors. ACP doesn't take a cut—it's just a protocol, not a middleman.

Q: Do I have to use ChatGPT? What about other AI assistants?

A: ACP is open and protocol-based, so it works with any AI assistant that supports it. ChatGPT is the most visible early adopter, but Claude, custom business assistants, and other AI platforms can all support ACP.

Q: What about my SEO and brand control?

A: ACP doesn't replace your website or traditional SEO. It complements it. You'll still want an online presence. But ACP adds a new discovery channel where your products become visible inside AI conversations.

The Real Opportunity: Time Is Now

The businesses that adopt ACP early will have a significant advantage:

First-mover dominance in their categories within AI assistants. With only three to five products typically shown per query, early adopters occupy the limited recommendation slots.

Lower customer acquisition costs before competition increases. Current ACP adoption is still in early stages. Merchants implementing now benefit from high-intent traffic without bidding wars.

Data advantage from early access to how customers shop through AI. Merchants active on ACP platforms now are learning how customers phrase queries, what attributes matter most for recommendations, and which products convert best.

Direct relationship with customers without relying on marketplace algorithms. Unlike marketplace models where the platform owns the customer relationship, ACP merchants retain direct customer relationships as the merchant of record.

Unlike past e-commerce shifts, this one is open and accessible. You don't need venture funding or a massive engineering team. You just need a product and willingness to show up in a new place where customers are looking.

Your Next Step: Become ACP-Ready

The path forward is simple:

Audit your current setup: What e-commerce platform or catalog system do you use?
Check for native ACP support: Does your platform already support it?
Choose an integration path: Platform native, ACP enabler service, or custom build
Expose your catalog: Point your product feed to an ACP endpoint
Test and optimize: Monitor orders, conversion rates, and customer feedback

The merchants who get this right early won't just survive the next wave of commerce—they'll thrive in it.

Final Thought

For decades, e-commerce has been about driving traffic to your website and converting browsers into buyers. ACP inverts that model. Instead of you chasing customers on Google or social media, you're meeting them where they already spend time: inside AI assistants, asking for exactly what they want.

That's not just a new sales channel. That's the future of commerce.

The conversational commerce market is projected to grow from $8.8 billion in 2025 to over $32 billion by 2035. With 700 million people already using ChatGPT weekly and 60% of U.S. consumers expecting to use AI shopping agents within the next year, the shift is already underway.

The question isn't whether ACP will matter. The question is: when will you be ready?
