Agentic Commerce Protocol (ACP)
Definition
The Agentic Commerce Protocol (ACP) is a standard for how AI agents initiate and complete checkout sessions with merchants programmatically. It gives agent-led buying a structured handoff into merchant checkout systems.
The Agentic Commerce Protocol, or ACP, is a protocol for how AI agents initiate, manage, and complete merchant checkout sessions programmatically. It focuses on the transaction handoff between an agent and a merchant, including how offers, carts, checkout steps, and permissions are structured for agent-led buying.
Use Case
A shopper asks an assistant to buy a replacement air purifier filter from a preferred brand. After confirming the exact SKU and delivery preference, the assistant uses an ACP-style flow to create a checkout session, pass the cart and shipping details to the merchant, and complete the purchase with the user's approval settings.
Examples
Assistant-to-merchant checkout
A shopping agent creates a structured checkout session instead of sending the user through a generic product-page flow.
Brand-approved buying handoff
A merchant exposes a machine-friendly checkout path so external agents can transact without scraping the site.
Why It Matters
Agentic commerce only becomes real when buying can move from recommendation into transaction. ACP matters because it gives merchants and platforms a cleaner, more controllable way to support agent-led checkout.
Today's E-commerce Impact
ACP is still early, but it reflects a broader shift: payment companies, AI platforms, and commerce vendors are building structured checkout paths for agents instead of assuming all buying starts in a browser.
Future Evolution
If protocols like ACP mature, merchants may expose dedicated agent checkout surfaces with clearer controls around pricing, fulfillment, fraud, and user consent. That would make agent traffic easier to support and measure at scale.
