Receipt, authorization data, card-present details, AVS/CVV results, and gateway logs.
Fulfillment evidence
Delivery confirmation, pickup records, signed agreements, service logs, or usage records.
Policy evidence
Refund, cancellation, return, subscription, and disclosure language.
Customer communication
Emails, messages, invoices, confirmations, and support notes.
