Where checkout changed
Shopify Checkout documentation places checkout extensions, interaction, and merchant logic inside the buying flow, which makes confirmation boundaries important before agent-driven checkout.
Checkout should let the buyer confirm amount, shipping, tax, discounts, contact details, payment method, and exception handoff instead of letting an agent keep clicking.
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
- Require human confirmation for payment, address changes, quantity changes, discount use, order submission, and refund requests
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Checkout without confirmation points can turn a growth channel into payment disputes and support cost. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
