Know who is buying
Check the shopping agent.
See the agent’s identity and a recommendation to accept, review, or decline before your store proceeds.
For merchant checkouts
The agent can spend more than the customer asked for.
A shopping agent can carry a real customer request and still exceed the purchase it was meant to make. Your backend verifies the agent, then enforces the operator's signed trace — audience, scope, and spending limit — before the card is touched.
For your store team
An agent places the order. Your store stays in control.
When AI shops for a customer, your team needs to know who is buying, what they can spend, and why an order can proceed.
Check the order
Keep the purchase within permission.
Check the cart against the customer’s signed purchase permission, including the store, allowed action, and spending limit.
Help your team follow up
Keep a record with the order.
Save the verification and checkout decision with the order so your team can refer to them when questions come up.
A familiar order problem
The customer said $149. The cart says $188.
A customer asks an agent to buy a replacement filter. The agent adds a protection plan that takes the total over the customer’s limit.
An identity check alone won’t catch that difference. The checkout check compares the order with the signed purchase permission and declines the session if the total is too high.

Before you get started
A few questions from your team.
What changes for your store, your shoppers, and the people handling orders.
Will this change checkout for regular shoppers?
Your integration can apply KYA checks to shopping agents while keeping the checkout flow for human shoppers unchanged. KYA does not charge the customer’s card.
What if an agent has no identity or purchase permission?
Your store decides whether to continue or ask for review. KYA checks the identity and signed purchase permission supplied by your integration. It does not automatically identify every shopping agent.
Does KYA block orders on Shopify?
Shopify checkout checks are currently advisory. Blocking checkout requires a Shopify cart and checkout validation Function. For a custom integration, the KYA checkout API can decline a session that exceeds the signed purchase permission.
