When an AI agent buys for a user, what authorization and dispute evidence should be kept?

Authorization should be understandable before the agent acts. Depending on the product, it may define the permitted product or category, spending limit, valid period, merchant or market restrictions, whether recurring purchases are allowed, when price changes require renewed consent, and how the user can pause or revoke authority.

Avoid treating a broad acceptance of terms as proof of every later purchase. Keep the authorization version, time, user confirmation and order linkage so the scope that applied to a particular transaction can be reconstructed.

A successful payment only proves an outcome; it does not explain how the purchase was requested. A useful trail can link the user account, agent or service instance, authorization, execution time, product selection, quoted price, order, payment attempt and final result.

Record enough to establish sequence and identity without collecting unnecessary sensitive data. Field design, retention and access controls should follow the product architecture, applicable privacy rules, payment-channel requirements and contractual responsibilities.

The product page, agent confirmation, order, receipt or invoice, statement descriptor, renewal terms, cancellation path and refund policy should describe the same purchase. The user should be able to understand what was bought, the amount and currency, whether the charge repeats, and how to stop or dispute it.

For subscriptions or autonomous repeat purchasing, use explicit limits and renewed confirmation where the price, scope or cadence changes materially. Clear disclosure reduces ambiguity but does not by itself prevent fraud, refunds or chargebacks.

Depending on the dispute and payment method, relevant material may include the authorization text and timestamp, agent execution events, product and price shown, order confirmation, customer acknowledgement, access or delivery records, cancellation timing, refund-policy display and support communications.

Evidence should be indexed to the order and retrievable within the applicable response window. Keeping evidence does not guarantee that a dispute will be won, and requirements vary by market, payment method, reason code and transaction type.

The product team controls the product, pricing, fulfilment and customer experience. An agent platform may provide identity, permission and execution context. A payment provider connects and processes payment capabilities. For approved transactions, a Merchant of Record may act as the disclosed seller and operate agreed checkout, billing, transaction records, customer transaction support, refunds and disputes.

Using a MoR does not make the product team disappear from the evidence chain. Product rights, accurate claims, fulfilment, user support evidence and responsibilities outside the agreed MoR scope remain with the product partner. Exact roles depend on the approved business, markets, capabilities and final agreement.
