Toss Payments is a South Korean payment gateway (PG) operated by Viva Republica, the company behind the Toss super-app. Its REST API lets merchants accept and manage online payments across cards, Korean easy-pay wallets (Toss Pay, KakaoPay, Naver Pay), virtual accounts, bank transfer, and mobile-phone billing. The Core API (base https://api.tosspayments.com) covers payment confirmation and cancellation, recurring billing keys, virtual account issuance, cash receipts, transaction and settlement queries, and seller payouts, with asynchronous results delivered by webhooks. Authentication is HTTP Basic using a secret API key.
