UCP Identity Linking
LiveVerifiedUCP spec capability (March 2026) that preserves shopper loyalty and member benefits (pricing, free shipping) across UCP-integrated platforms when shoppers are logged in.
UCP Identity Linking is a capability that allows shoppers to carry their logged-in benefits (member pricing, loyalty points, free shipping thresholds) when using UCP-integrated AI shopping agents and platforms, just as they would when shopping directly on a retailer's own site.
Without Identity Linking, a shopper using an AI agent to purchase from a store might lose their loyalty status and associated perks. Identity Linking solves this by establishing a secure link between the shopper's identity on the retailer's platform and the UCP session, using established open standards.
Why This Matters for UCP
Identity Linking bridges the gap between direct merchant shopping and AI-mediated commerce, ensuring shoppers do not lose loyalty benefits when using UCP-integrated AI agents.

Good tool for UCP conformance testing. Runs fast and the output is easy to parse in CI. Would like a JSON output mode — currently only text.

This saved us days of work. Dropped it into our pipeline and had UCP endpoint validation running in about 20 minutes. Documentation is accurate.

The best developer tool in this category. TypeScript types are correct and complete. Error messages actually tell you what went wrong.

Solid tool. The test suite coverage is excellent. I found one edge case in the payment token validation that the maintainers fixed within 48 hours.
