Google Street View Publish API는 HTTP 및 JSON에 기반하므로 모든 표준 HTTP 클라이언트가 API에 요청을 전송하고 응답을 파싱할 수 있습니다.
그러나 Google API 클라이언트 라이브러리는 우수한 언어 통합, 향상된 보안, 사용자 승인이 필요한 호출에 대한 지원을 제공합니다. 이 클라이언트 라이브러리는 다양한 프로그래밍 언어로 제공되므로 HTTP 요청을 직접 설정하고 응답을 파싱하지 않아도 됩니다.
시작하려면 개발에 사용할 프로그래밍 언어를 선택합니다. 아직 더 많은 언어를 추가하고 있습니다.
