Where checkout changed
Stripe Universal Commerce Protocol centers merchants, payment, authorization, and transaction responsibility in agent-assisted buying.
Before an agent enters checkout, the page should clarify merchant of record, payee, refund route, actions requiring buyer confirmation, and what data becomes part of the order.
Do not trust one conversion number
The useful question is no longer whether a purchase happened; it is which step created the hesitation, missing fact, or measurement gap.
Check the event model
- Before pricing or checkout, state merchant entity, authorized actions, payment recipient, refund route, and support path
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
One-click buying language without responsibility boundaries increases mistaken purchases, refunds, compliance issues, and support disputes. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
