Conceptual Architecture

What Buyer Consent Does

The Buyer Consent extension adds privacy-compliant consent collection to UCP checkout sessions. It enables merchants to collect and record buyer consent for data processing, marketing, and terms acceptance — satisfying GDPR, CCPA, and other privacy regulations.

Why It Exists

Agentic commerce introduces a new challenge: an AI agent acts on behalf of the buyer. Regulations require explicit, informed consent for data processing. This extension standardizes how consent is requested, granted, and recorded across the UCP protocol.
