Every request/response body is a JWT (JWS) signed with the merchant Secret Key using HMAC SHA-256; there is no Authorization header and the merchant is identified by merchantID inside the signed payload.

Base URL: https://pgw.2c2p.com/payment/4.3 (production) or https://sandbox-pgw.2c2p.com/payment/4.3 (sandbox). Endpoint paths are confirmed from developer.2c2p.com; payload fields are modeled.",
