최소 버전을 확인하세요

SDK : 1.2.1 이상
토스앱 (본인확인) : 5.233.0 이상
토스앱 (원터치 인증) : 5.236.0 이상

getTossAppVersion 함수를 사용하여 토스앱 버전을 체크해보세요.

1. AccessToken 받기

토스 본인확인을 위한 Access Token을 발급받아요.
발급된 토큰은 이후 모든 API 호출의 Authorization 헤더에 사용돼요.

토큰에는 만료 시간(expires_in) 이 있어요. 만료 시 새 토큰을 발급해야 하고, 유효한 토큰이 있으면 재발급을 피해서 불필요한 호출을 줄여 주세요.

Base URL: https://oauth2.cert.toss.im
Endpoint: /token
Method: POST
Content-Type: application/x-www-form-urlencoded

요청 헤더

이름	타입	필수값 여부	설명
Content-Type	string	Y	`application/x-www-form-urlencoded`

요청 파라미터

이름	타입	필수값 여부	설명
grant_type	string	Y	고정 값: `client_credentials`
scope	string	Y	인증 요청 범위 (예: `ca`)
client_id	string	Y	고객사에 발급된 클라이언트 아이디
client_secret	string	Y	고객사에 발급된 클라이언트 시크릿

2. 인증 요청하기

토스 인증 서버에서 txId를 발급받아 본인확인 절차를 시작해요.

BaseURL : https://cert.toss.im
Endpoint : /api/v2/sign/user/auth/id/request
Method : POST
Content-type : application/json

2-1. 개인정보 기반 인증

고객의 이름·생년월일·전화번호 를 암호화 후 전송하는 방식이에요.
보안을 위해 세션키(sessionKey)는 매 요청마다 새로 생성하세요.

요청 헤더

이름	타입	필수값 여부	설명
Authorization	string	Y	`Bearer {Access Token}`
Content-Type	string	Y	`application/json`

요청 파라미터

이름	타입	필수값 여부	설명
requestUrl	string	Y	토스 본인확인 사용 시 돌아갈 고객사 앱스킴
requestType	string	Y	`USER_PERSONAL`
triggerType	string	Y	`APP_SCHEME`
userName	string	Y	암호화 필수
userPhone	string	Y	숫자만, 암호화 필수
userBirthday	string	Y	`YYYYMMDD`, 암호화 필수

}

응답의 txId를 사용해 appsInTossSignTossCert 함수를 호출하면 토스앱 인증 화면이 실행됩니다.
인증 화면 호출하기 를 참고해주세요

3. 인증 화면 호출하기

SDK를 통해 연동해주세요.

응답에서 받은 txId를 사용해 appsInTossSignTossCert 함수를 호출하면, 토스앱 인증 화면이 실행돼요. appsInTossSignTossCert를 확인해 주세요.

토스앱 최소 버전을 확인하세요

토스 인증(requestType: USER_PERSONAL): 토스앱 5.233.0 이상
토스 원터치 인증(requestType: USER_NONE): 토스앱 5.236.0 이상

getTossAppVersion 함수를 사용하여 토스앱 버전을 체크해보세요.

4. 본인확인 상태 조회하기

사용자의 현재 인증 진행 상태를 조회해요.
txId를 사용해 현재의 인증 단계 (REQUESTED, IN_PROGRESS, COMPLETED, EXPIRED)를 확인할 수 있어요.

주의하세요

상태조회 API는 진행 상태 확인용이에요.
최종 인증 성공 여부는 결과조회 API로 판별해야 해요.

status 값

값	설명
REQUESTED	토스 인증서버에서 사용자의 토스 앱으로 인증이 요청된 상태
IN_PROGRESS	사용자가 인증을 진행 중인 상태
COMPLETED	고객이 인증을 완료한 상태 (최종 확정은 결과조회 API로 판단 해야해요)
EXPIRED	유효시간 만료로 인증 진행이 불가한 상태

5. 본인확인 결과 조회하기

인증이 완료된 사용자의 결과 정보를 조회해요.
조회는 반드시 서버-서버 통신으로 진행해 주세요.
본인확인 결과로 수집한 정보는 서버에 안전하게 저장하고, 이후 전자서명/간편인증 시 해당 정보와 비교·검증 해 주세요.

주의하세요

결과조회 API는 성공 기준으로 최대 2회까지만 조회가 가능해요.
사용자 인증을 끝마친 후 60분(1시간) 이내 결과 조회를 끝내야 해요.
60분을 초과하면 결과 조회가 제한되며 인증 요청 API부터 다시 시작해야 해요.
