Google Wallet API에 대한 요청 인증

Google Wallet API에 대한 요청은 월렛 API가 애플리케이션에서 요청을 작성했음을 식별할 수 있도록 인증되어야 합니다.

시작하기 전에 Google Wallet REST API 및 Google Wallet Android SDK에 대한 사용자 인증 정보를 제대로 생성하고 등록했는지 확인하세요.

Google Wallet REST API 요청

Google Wallet REST API에 대한 요청은 액세스 토큰을 얻기 위해 Google Wallet REST API Google Cloud 서비스 계정 키를 사용하여 인증됩니다.

Google API 클라이언트 라이브러리는 인증과 API 요청을 처리합니다. 다음 예에서 사용하는 원하는 프로그래밍 언어의 라이브러리를 설치해야 합니다.

먼저 필요한 라이브러리 가져오기를 수행하고 서비스 계정 JSON의 일부 변수와 저장할 발급기관, 클래스, 순 사용자, 객체의 ID를 정의합니다.

Google 월렛 Android SDK 요청

Google 월렛 Android SDK를 사용하는 요청은 앱 서명 인증서를 사용하여 자동으로 인증됩니다. Android SDK는 서명 인증서의 SHA-1 지문을 자동으로 생성하고 이를 Google Wallet API 요청에 포함합니다.

앱 서명 인증서의 SHA-1 디지털 지문을 생성하고 등록하는 방법에 대한 자세한 내용은 Google 월렛 Android SDK에 대해 앱 승인을 참조하세요.
