发卡机构账号配置

前提条件

请务必先完成以下步骤，然后再继续：

• 前提条件

确定要启用智能触碰功能的账号

在继续操作之前，您需要确定哪个账号将指定为 兑换发卡机构账号。确定这一点的方法有两种：

创建新的发卡机构账号

新账号的账号联系信息中必须包含商家的 信息。有关如何在 Google Pay 和钱包 请参阅此 支持文章 以下代码示例演示了如何使用 Google Wallet API：

Java

/**
 * Create a new Google Wallet Issuer account.
 *
 * @param issuerName The Issuer's name.
 * @param issuerEmail The Issuer's email address.
 * @throws IOException
 */
public void CreateIssuerAccount(String issuerName, String issuerEmail) throws IOException {
  // New Issuer information
  Issuer issuer =
      new Issuer()
          .setName(issuerName)
          .setContactInfo(new IssuerContactInfo().setEmail(issuerEmail));

  Issuer response = service.issuer().insert(issuer).execute();

  System.out.println("Issuer insert response");
  System.out.println(response.toPrettyString());
}

PHP

  $response = $this->service->issuer->insert($issuer);

  print "Issuer insert response\n";
  print_r($response);
}

    print('Issuer insert response')
    print(response.text)

}

最初，只有创建发卡机构的主账号（服务账号或用户） 账号拥有访问权限。您需要更新发卡机构的权限 添加应该能够 管理卡券。以下代码示例演示了如何更新发卡机构 账号权限。

使用现有账号

应使用以下条件来确定您是否可以使用 Issuer 包含现有卡券类的账号。

• 如果用于开发卡券的发卡机构账号包含 您必须代表 商家。
• 如果用于开发卡券的发卡机构账号仅包含类 可以使用该标识符

如果账号满足这些条件，您必须更新联系信息 包含商家信息 name 标识商家。只有您才拥有此账号的 API 访问权限。 其他卡券开发者应创建自己的发卡机构账号。

兑换发卡机构账号配置

使用 Google Pay 和钱包控制台

在兑换发卡机构账号中，您需要按照以下步骤操作：

1. 前往 Google Wallet API 部分
2. 选择其他功能
3. 选择添加身份验证密钥。
4. 上传公钥（.pem 文件）并指定密钥版本
5. 选择创建身份验证密钥。

身份验证密钥获取后，系统就会向您提供收款方 ID 已成功上传。

注意 ：如果您的终端提供商在您提供 收集器 ID，可以使用下面的演示密钥生成一个。请务必 从终端获取真实的公钥后，移除此演示密钥 提供商。

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEchyXj869zfmKhRi9xP7f2AK07kEo
4lE7ZlWTN14jh4YBTny+hRGRXcUzevV9zSSPJlPHpqqu5pEwlv1xyFvE1w==
-----END PUBLIC KEY-----

使用 Google Wallet API

上传公钥

要使用 Google Wallet API 分配公钥和密钥版本，您需要： 需要向 Issuers 端点发出 PATCH 请求。

PATCH https://walletobjects.googleapis.com/walletobjects/v1/issuer/{issuerId}

重要提示： smartTapMerchantData.authenticationKeys[].id 属性必须为 一个介于 1 到 2,147,483,647（含）之间的整数。每个公钥都必须 具有唯一的密钥版本。

PATCH 请求正文类似于以下内容：

{
    "smartTapMerchantData": {
        "authenticationKeys": [
            {
                "id": 1,
                "publicKeyPem": "-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"
            },
            {
                "id": 2,
                "publicKeyPem": "-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"
            }
        ]
    }
}

以下代码示例演示了如何更新发卡机构账号以包含 演示公钥：

Java

获取核销方 ID

添加任何密钥和密钥版本后，您可以使用 Google Wallet API 获取 向 Issuers 端点发出 GET 请求，以输入您的收款方 ID。

GET https://walletobjects.googleapis.com/walletobjects/v1/issuer/{issuerId}

发卡机构账号管理

卡券组织

管理卡券类和对象的两种常用方法 多个商家：

• 所有商家使用一个集中的发卡机构账号
• 每个商家有一个新的发卡机构账号

例如，Foo-Loyalty 为两个商家分别管理不同的会员回馈活动： ILuvCoffee 和 TeaLuv。其卡券类可在以下任一位置进行管理： 方法：

做法	说明
单一发行方账号	在一个发卡机构下包含所有会员卡类 账号“Foo-Loyalty”建议使用此选项 如果您打算跟踪您的卡券在哪里 都是在类级别兑换的。它也是 如果您从不向商家授予 对该发卡机构账号的 API 访问权限。
单独的发卡机构账号	创建两个单独的发卡机构账号：“iLuvCoffee” 通过 Foo-Loyalty”以及“teaLuv via Foo-Loyalty”。 如果您希望 特定发卡机构账号下的所有类 可在商家级别兑换，或者 您计划向 merchants API 授予 发卡机构账号。

兑换发卡机构账号

确定正确的兑换时，需要考虑以下两种情况 要使用的发卡机构账号。

场景 1：商家已在使用智能触碰

如果商家确认他们已经使用自己的 终端（商家已设置为兑换发卡机构），请按照 具体步骤如下：

1. 申请商家的兑换发卡机构 ID
2. 将商家的兑换发卡机构 ID 添加到 redemptionIssuers 属性 （与卡券类相关联）

场景 2：商家初次使用智能触碰功能

在这种情况下，商家拥有支持智能触碰但还不支持的终端 是否使用了该功能商家、终端提供商或卡券开发者 需要执行一次性设置，才能在商家的终端上启用智能触碰功能。

如需了解详情，请参阅 商家配置。
