Where checkout changed
Visa and OpenAI, AI commerce, payment authorization, and agent purchases show that AI shopping depends on permission design.
If an AI agent buys for a user, the user needs to see authorization scope, spending limit, merchant, refund, and dispute path.
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
- Add four fields to AI shopping flows: authorized party, spend limit, validity window, and revocation path
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Without authorization boundaries, faster conversion becomes trust risk. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
