4.1.3 Google Ads 账号创建或现有账号选择

价值和业务影响

---

除了 Merchant Center 账号外，您的商家还需要拥有 Google Ads 账号。如果您已选择直接结算选项，建议您 还可以使用现有账号（他们可能已经在使用该账号） 投放其他类型的广告）。

您可以使用 Google Ads API 以编程方式创建 Google Ads 账号。 您也可以按照 设置 Google Ads 账号中介绍的步骤是一种可扩展的方法， 使用程序化的方式

注意：

• 您为账号选择的币种一经确定便无法更改 。用于满足商家账号的任何特定结算需求。
• 用户名是商家在其客户账号中看到的名称。
• 商家创建账号后，Google 会向您发送确认电子邮件 代表其账号。

合并结算

如果您选择使用合并结算，则可以完成结算设置 完全在后端进行，但接受服务条款除外。

在直接结算的情况下，Google 服务条款会显示给 在 Google Ads 或 Merchant Center 中进行结算设置时与商家联系， 您不需要在界面中向用户公开这些示例。在综合 结算场景，您必须展示购物广告政策，并且 Google Ads 政策，并记录其接受情况（包括 日期和版本）。

直接结算

本部分介绍的用户体验指南适用于直接结算场景， ，以便向商家呈现整个新手入门流程。

• 如果商家尚未完成 OAuth 步骤，请提示他们执行此操作 是这样。我们建议在流程开始时完成一次 OAuth 以获取 Google Merchant Center 范围和 Google Ads 范围。 检测商家的所有现有 Google Ads 账号。如果一个或多个 则提供关联其中任何一个账号的选项。

• 如果商家选择创建新账号，请尝试预先填充 字段包含国家/地区、时区和币种，其中包含有关商家 可用的业务理想情况下，商家不应该 您手动提供此信息，创建新的 Google Ads 账号 提供一键式体验

• 创建账号后，您可以通过编程方式将 Google Ads 账号与 与商家的 Merchant Center 客户账号相关联。

下面简要概述了 Google Ads 账号关联步骤的变体。 如果您参与了奖励优惠券计划，并且商家可能 有资格使用优惠券，请在 Google Ads 账号中提供优惠券信息 连接步骤（详见下一部分）。

技术指南

要使用 API 管理 Google Ads 账号，您必须已通过身份验证 作为现有 Google Ads 经理账号的用户。会创建新账号 。

以下示例展示了如何获取广告系列的账号层次结构： 方法是构建一个 GAQL 语句来查询所有子级 CustomerClient 中通过 client_customer 字段指定的账号， 并在子级经理账号中以递归方式执行该操作。您必须提供 login-customer-id 并将其设置为您的经理账号 ID，以运行任何 因为他们通过经理账号访问子账号。

=head1 NAME

get_account_hierarchy

=head1 DESCRIPTION

Gets the account hierarchy of the specified manager customer ID and login customer
ID. If you don't specify them, the example will instead print the hierarchies
of all accessible customer accounts for your authenticated Google account.

Note that if the list of accessible customers for your authenticated Google
account includes accounts within the same hierarchy, this example will retrieve
and print the overlapping portions of the hierarchy for each accessible customer.

=head1 SYNOPSIS

    -help                       Show the help message.
    -manager_customer_id        [optional] The Google Ads manager customer ID.
    -login_customer_id          [optional] The login customer ID.

如果商家想要使用现有 Google Ads 账号，请检查现有账号 使用 CustomerService 的 ListAccessibleCustomers 方法创建账号。

选好要使用的账号后，请在这两个账号之间 Google Ads 客户账号和经理账号。关联两个账号必须始终 然后从经理账号发起关联请求，然后必须在账号一级接受该关联请求 客户账号。关联状态会存储在 CustomerClientLink 或 CustomerManagerLink。请参阅 有效状态列表。使用 PENDING 发起关联，使用 ACTIVE 来发起关联。 接受该链接。

在两个既有的 Google Ads 账号之间建立关联，可以分三步完成。

1. 在以经理账号身份进行身份验证时，请向 创建状态为 PENDING 的 CustomerClientLink。

2. 在以经理账号身份进行身份验证时，查询 GoogleAdsService 查找您创建的 CustomerClientLink 的 manager_link_id。

3. 在以客户账号身份进行身份验证时，接受来自 方法是将 CustomerManagerLink 更改为具有状态 ACTIVE。

。

提示： 您可以通过以下方法检查您是否成功创建了商家账号 使用您的经理账号凭据登录 Google Ads，然后转到 “账号”部分商家还可以了解哪些经理账号 对 Google Ads 账号的访问权限。客户列表 管理员会显示在设置 >账号设置 >账号访问权限。
