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 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 관리자콘솔 내 결제연동 탭에서 발급받으실 수 있습니다.

인증 관련 API를 제외한 모든 API는 HTTP Authorization 헤더로 아래 형식의 인증 정보를 전달해주셔야 합니다.

  • Authorization: PortOne MY_API_SECRET

GET 요청 시 Body 대신 Query 사용하기

GET 요청 시에 Body를 전달해야 하는 경우, Body 대신 Query를 사용할 수 있습니다.

이 경우, Body 객체를 requestBody Query 필드에 넣어주시면 됩니다.

하위호환성

포트원이 제공하는 모든 Stable API에 대해 아래와 같은 하위호환성이 보장됩니다.

  1. 현재 사용 가능한 입력 형식은 앞으로도 사용할 수 있습니다.

    • 입력 형식 내 필드 정의가 삭제되지 않습니다.
    • 필수 입력 정보가 추가되거나, 선택 입력 정보가 필수로 변경되지 않습니다.

      • 오로지 선택 입력 정보만 추가될 수 있습니다.
    • 하위 필드의 형식(타입) 또한 위 규칙을 지키며 변경됩니다.
    • enum 타입의 값이 삭제되지 않습니다.
  2. 출력 형식이 확장될 수 있지만, 축소되지 않습니다.

    • 출력 형식 내 필드 정의가 삭제되지 않습니다.
    • 사용 중인 필수 출력 정보가 선택사항으로 변경되거나 출력 시 누락되지 않습니다.

      • 이미 존재하는 용례 내에서는 필수 출력 정보가 언제나 유지됩니다.
      • 단, 기능이 추가 및 확장되는 등 새로운 용례로 사용될 때의 출력 정보에 한하여 선택사항으로 변경될 수 있습니다.
    • 하위 필드의 형식(타입) 또한 위 규칙을 지키며 변경됩니다.
    • 단, 새로운 필드 또는 enum 값, oneOf 케이스가 추가될 수 있습니다.

      • 알지 못하는 필드 및 값이 주어지더라도 crash가 발생하지 않도록 유의하여 개발해주세요.

UNSTABLE이 표기된 일부 API의 경우, 위 하위호환성 정책과 무관하게 변경 및 지원 종료될 수 있으니 이용에 유의하세요.
