Implementation guidance for UCP identity linking using OAuth2 authorization code flow to link buyer accounts between platforms and merchants for personalized ch
This skill documents how to implement UCP Identity Linking using the OAuth 2.0 authorization code flow. It explains the architecture and practical steps for platforms and merchants to securely link buyer accounts so agents can access loyalty data, saved addresses, and personalized pricing during checkout. The skill covers discovery, required endpoints, token exchange, and recommended metadata publishing.
Use this skill when building account linking or SSO integrations between a Platform and a Business under the UCP (Universal Commerce Platform) specification — for example when enabling agents to act on behalf of buyers, apply account-based discounts, or surface order history during checkout. It is relevant during integration design, API implementation, and security reviews.
Useful for developer assistants and integration engineers using tools that support web lookups and API integration guidance (claude-code, codex, cursor, general developer agents).
