JSON 웹 토큰은 정보를 JSON 객체로 안전하게 전송하기 위해 일반적으로 사용되는 업계 표준입니다. Google Wallet API를 사용할 때는 JWT('jot'라고 발음됨) 형식으로 패스 인스턴스를 만드는 데 사용할 패스 객체의 세부정보를 인코딩한 다음 Google Wallet API에 대한 요청으로 JWT를 전송합니다.
JWT는 Google Wallet API로 전송되기 전에 공유 비밀번호로 서명함으로써 안전하게 보호됩니다. Google Wallet REST API를 사용하는 경우 서명 비밀번호는 Google Cloud 서비스 계정 키입니다. Google 월렛 Android SDK를 사용하는 경우 서명 비밀번호는 Android 앱의 SHA-1 지문입니다.
JWT에서 패스 인코딩
EventObject가 생성되면 다음 스니펫과 같이 payload.EventObjects 속성이 있는 서명되지 않은 JWT로 래핑합니다.

JWT 서명
JWT는 Google Wallet API로 전송되기 전에 공유 비밀번호로 서명함으로써 안전하게 보호됩니다. Google Wallet REST API를 사용하는 경우 서명 비밀번호는 Google Cloud 서비스 계정 키입니다. Google 월렛 Android SDK를 사용하는 경우 서명 비밀번호는 Android 앱의 SHA-1 지문입니다.
웹, 이메일 및 SMS
JWT는 Google 월렛 비즈니스 콘솔에서 승인한 Google Cloud 서비스 계정과 연결된 서비스 계정 키를 사용하여 서명되어야 합니다. Google Wallet API는 JWT 서명을 확인하여 이러한 클레임을 검증합니다.
JWT에 서명하면 'Google 월렛에 추가'를 만드는 데 사용할 수 있는 토큰이 생성됩니다. 사용자에게 패스를 발급하는 데 사용할 수 있는 링크입니다.
