PortOne REST API - V2
API 결제, 결제 정보 조회, 결제 취소 등의 기능을 제공하는 REST API입니다.
V2 API hostname: api.portone.io
요청 및 응답 형식
요청과 응답의 본문은 JSON 형식입니다.
API 응답에 포함된 필드는 별도 안내 없이 추가될 수 있으니, 알지 못하는 필드가 있는 경우에는 무시하도록 개발해 주세요.
API 매개 변수 중 URL 경로에 들어가는 문자열 값이 있는 경우, URL 경로에 들어갈 수 없는 문자열은 이스케이프하여야 합니다. 자바스크립트의 encodeURIComponent 함수 등을 사용할 수 있습니다.
인증 방식
V2 API를 사용하기 위해서는 V2 API Secret이 필요하며, 포트원 콘솔 내 결제연동 탭에서 발급받을 수 있습니다.
인증 관련 API를 제외한 모든 API는 HTTP Authorization 헤더로 인증 정보를 전달해 주셔야 합니다. Authorization 헤더에 전달하는 형식은 두 가지 중 하나입니다.
- API Secret 직접 사용 (간편)
Authorization: PortOne MY_API_SECRET - 액세스 토큰 사용
Authorization: Bearer MY_ACCESS_TOKEN
