Прежде чем приступить к работе с веб-API, убедитесь, что вы выполнили все необходимые условия. Чтобы продолжить работу с веб-API, у вас должны быть учетная запись службы и ключ учетной записи службы , а также необходимо предоставить доступ к своей учетной записи службы для вызова API Google Кошелька .
Загрузите пример кода на GitHub , чтобы запустить фрагменты кода, указанные в шагах ниже.
Аутентификация и авторизация
Запросы к API Google Кошелька должны быть аутентифицированы, чтобы API мог определить, что запрос выполняется вашим приложением. Это достигается за счет использования ключа учетной записи службы для получения токена доступа.
Сначала выполните необходимый импорт библиотеки и определите некоторые переменные для JSON учетной записи службы, а также идентификаторы для издателя, класса, уникального пользователя и объекта, которые будут сохранены.

Создание объекта Passes
Объект Passes является экземпляром класса Passes. Чтобы создать Passes Object, вы должны предоставить следующие атрибуты:
-
classId:idкласса Passes. -
id: уникальный идентификатор для представления подарочной карты клиента.
Обратитесь к руководству по шаблону для получения дополнительной информации о том, как эти атрибуты представлены в проходе.
Пример кода для создания объекта Passes:

После завершения объект Passes вашего клиента будет создан на сервере. Однако на данном этапе объект Passes не был связан с пользователем Google или его устройством. Чтобы пропуск был связан с пользователем Google Кошелька, пользователь должен сначала добавить пропуск в Google Кошелек .
Добавление в Google Кошелек
Добавление пропуска в Google Wallet связывает объект Passes с пользователем Google и может быть инициировано только в контексте входа в учетную запись Google. Этого можно добиться, перенаправив пользователя по URL-адресу «Добавить в Google Кошелек».
URL-адрес добавления в Google Wallet — это динамически сгенерированный URL-адрес, который содержит следующую информацию об идентификаторе объекта Passes, созданном на предыдущем шаге. Эта информация закодирована как JSON Web Token (JWT) .
Веб-токен JSON (JWT)
JWT содержит утверждения, которые вы (эмитент) делаете об объекте Passes, который будет сохранен пользователем. JWT должен быть подписан с помощью private_key из ключа учетной записи службы, полученного на этапе создания учетной записи службы , и Google проверит эти утверждения, проверив подпись JWT.
Утверждения JWT должны иметь следующую структуру:
{
"aud": "google",
"origins": ["https://example.com"],
"iss": "my-service-account@my-project-id.iam.gserviceaccount.com",
"typ": "savetowallet",
"payload": {
"giftCardObjects": [
{
"id": "PASSES_OBJECT_ID_1234567890"
}
]
}
}
Создайте claims JWT (шаг 1) и получите token , подписав утверждения с помощью private_key ключа учетной записи службы (шаг 2):

Получив подписанный JWT, вы можете использовать эту информацию для создания ссылки «Добавить в Google Кошелек» .
Добавить ссылку в Google Кошелек
Ссылка «Добавить в Google Кошелек» имеет следующий формат:
https://pay.google.com/gp/v/save/{token}
Эта ссылка может быть встроена в вашу веб-страницу или отправлена по электронной почте в виде гиперссылки. Его также можно отправить клиенту, используя другие каналы, такие как чат и SMS.
Безопасная длина закодированного JWT составляет 1800 символов. Если ваш JWT ниже этого предела, весь объект может быть включен в подписанный JWT. Ваши JWT должны оставаться ниже этого предела. Если длина превышает 1800 символов, сохранение может не работать из-за усечения веб-браузерами.
Кнопка «Добавить в Google Кошелек»
Для достижения наилучших результатов используйте кнопки Google Кошелька на своей веб-странице, в электронной почте или в приложении для Android.
Кнопка Google Wallet может отображаться двумя способами:
- Кнопку JavaScript Web можно использовать для веб-сайтов.
- Ссылку JWT с кнопкой можно использовать для электронной почты, SMS, приложений и веб-сайтов.
[ТОЛЬКО ТЕСТ] проходит успешно
Когда вы все еще находитесь в демонстрационном режиме, все созданные вами пропуска будут иметь дополнительный текст «[ТОЛЬКО ТЕСТ]» в названии вашего пропуска. Это делается для того, чтобы отличить демонстрационные проходы от живых пропусков. После того, как вы получите разрешение от нашей команды, эти проходы в демонстрационном режиме больше не будут содержать дополнительный текст, когда пользователь повторно открывает приложение кошелька на подключенном устройстве.
