Agentic Commerce Protocol

Use the Agentic Commerce Protocol to enable AI agents to complete purchases on behalf of buyers.

The Agentic Commerce Protocol (ACP) is an open standard created by Stripe, OpenAI, and Meta that defines how AI agents interact with businesses to complete purchases on behalf of buyers. See agenticcommerce.dev for the full specification.

ACP defines composable building blocks for agent-driven commerce:

Agentic checkout : Create, update and complete checkout sessions with cart management, fulfilment options and payment processing.
Cart and feed : Browse product catalogues and manage shopping carts before checkout.
Delegate payment : Securely pass payment tokens between buyers, agents and businesses using payment handlers.
Delegate authentication : Delegate authorisation with OAuth 2.0 and allow agents to act on a buyer’s behalf with a business.
Orders and webhooks : Use webhooks to track lifecycle updates for order confirmation, shipping, delivery and refunds.
