  title: Toss Payments Core Billing Virtual Accounts API
  description: 'The Toss Payments Core API is a REST interface for accepting and managing online payments in South Korea across cards, easy-pay wallets (Toss Pay, KakaoPay, Naver Pay), virtual accounts, bank transfer, and mobile-phone billing. This document models a representative, grounded subset of the Core API: payment confirmation and cancellation, recurring billing keys, virtual account issuance, cash receipts, transaction and settlement queries, and marketplace payouts. All requests authenticate with HTTP Basic auth - the secret API key is used as the username with an empty password, Base64 encoded (`Authorization: Basic base64(secretKey:)`). Asynchronous results (virtual account deposits, foreign payment cancellations, Brandpay and payout status changes) are delivered by webhooks, which are out of scope for this REST document. Field names follow the Korean documentation, translated where helpful. This is a modeled subset authored by API Evangelist from the public documentation, not an official Toss Payments OpenAPI artifact.'
