Danal (다날) on a Mac
Danal payments (cards, mobile billing) · E-Commerce
Danal is a major Korean PG and the largest mobile-carrier billing (휴대폰결제) provider. Its newer developer center documents a unified REST API on one-api.danalpay.com that uses Basic auth with the merchant Secret Key; keys look like 'SK_TEST_...' for test. The docs say the Secret Key is issued only after the contract is fully completed, and test-stage keys come through the sales/contract contact. The documented server APIs are approve, cancel, virtual account, NotiUrl and billing; no read-only lookup endpoint was found. Why no verify request: No read-only endpoint is documented. POST https://one-api.danalpay.com/payments/confirm validates the body before authenticating: a fake key with a short transactionId returned HTTP 400 INVALID_REQUEST, so it cannot be used as a cheap key check without a real-looking transaction ID.
