결제 준비

엑심베이는 요청된 결제의 위변조 방지를 위해 파라미터 유효성을 검증하고 있습니다. 결제 과정에서 fgkey 는 아래처럼 두 번 필요합니다.

  1. 1. SDK 호출 전: 결제 준비 API로 fgkey를 생성해 결제창을 띄울 때 사용합니다.
  2. 2. status_url로 응답받은 후: 결제 검증 API에 응답받은 파라미터를 그대로 보내 유효성을 검증을 진행합니다.

SDK 호출 전 준비

SDK를 사용해 결제창을 띄우기 전 결제 준비 API를 호출해 요청된 결제의 위변조 방지를 위한 fgkey를 생성하세요.

응답

아래와 같이 응답에서 생성된 fgkey를 확인할 수 있습니다. 생성된 fgkey를 그대로 결제창을 호출할 때 넣어서 보내야 합니다.

응답 
                  
{
  	"rescode": "0000",
  	"resmsg": "Success",
  	"fgkey": "0E9BE04BA239A519E68171F26B68604ADA0A85C8350DBF5C8C0FCCF98461DB09"
  }

SDK 응답받은 후 준비

SDK로 결제창을 호출한 뒤 엑심베이 서버에서 status_url로 응답한 파라미터에도 fgkey의 유효성 검증도 필요합니다.
위변조 방지를 위해 가맹점은 응답 파라미터를 그대로 결제 검증 API로 보내 엑심베이 서버에서 응답으로 보낸 fgkey와 일치하는지 확인할 수 있습니다.

엑심베이 서버에서 status_url로 응답한 파라미터는 아래와 같이 쿼리스트링 형식으로 보내집니다.

statusurl을 정상적으로 수신되면 주문완료 처리 후 반드시 해당 페이지의 마지막에 rescode와 resmsg를 출력해야 합니다.
• 처리성공: rescode=0000&resmsg=Success • 처리실패: recode=실패코드&resmsg=실패메시지

status_url은 중복 호출될 수 있습니다. 주문이 중복 처리되지 않도록 주의가 필요하며, transaction_id로 중복승인과 호출에 대해서 확인할 수 있습니다.

쿼리스트링으로 응답받은 파라미터를 빠짐없이 결제 검증 API 요청 파라미터로 전송해주세요. 결제 검증 API로유효성 검증이 마무리되면 결제가 마무리됩니다.
