Google Reseller API получает GoogleJsonResponseException: 403 Forbidden

try {
        try {

        Reseller service = GoogleResellerApiUtil.getResellerService();

        Customer customerRecord = service.customers().get("acme.com").execute(); //crashes here
    // "acme.com" is also used in the example from Google
        System.out.println(customerRecord.toString());


    } catch (GoogleJsonResponseException e) {
        e.printStackTrace();
    }

И это класс, который я использую для подключения к API. Я предоставил файл p12, и он использует учетную запись службы, при вызове API он выдает себя за одного из суперадминистраторов, поэтому ему должно быть разрешено совершать все вызовы.

На данный момент я использую только область чтения.

    private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

        GoogleCredential credentials = null;

        try {
            credentials = new GoogleCredential.Builder()
                .setTransport(HTTP_TRANSPORT)
                .setJsonFactory(JSON_FACTORY)

                .setServiceAccountPrivateKeyFromP12File(new File(PRIVATE_KEY_FILE))
                .build();
        } catch (GeneralSecurityException e) {
            e.printStackTrace();
        }

        System.out.println("credential has been build, returning credential "); //this gets printed, so I think the credentials are valid?
    return credentials;
}

    /**
     * Build and return an authorized Reseller client service.

    public static Reseller getResellerService() throws Exception {
        Credential credential = getCredentials();
        return new Reseller.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, credential)
            .setApplicationName(APPLICATION_NAME)
            .build();
    }
}

Но при звонке получаю следующее сообщение об ошибке:

  "code" : 403,
