Клиентские библиотеки GAPI

Мы рекомендуем использовать наши клиентские библиотеки GAPI для конкретных языков, чтобы обеспечить лучший опыт, чем разработка с использованием необработанного REST или gRPC для связи между серверами.

Если библиотеки на языке вашего приложения не существуют, мы рекомендуем использовать конечные точки gRPC или REST Fleet Engine .

Для аутентификации с помощью Fleet Engine у ​​вас должен быть подписанный веб-токен JSON. Подробнее см. в разделе Аутентификация и авторизация .
