服务账号是一种 Google 账号，可供应用通过 OAuth 2.0 以编程方式访问 Google API。此操作不需要人工授权，但需要使用只有您的应用可以访问的密钥文件。
在详细了解服务账号之前，建议您考虑采用我们强烈推荐的替代方法（它比实施 OAuth 2.0 已安装应用流程更简单）。采用这种方法时，用户必须对应用进行手动授权，才能生成刷新令牌，但由于这些令牌永远不会过期，因此用户只需进行一次授权即可。
仍在阅读？好的，您可以通过以下任一方式实现服务账号：
- 如果您的用户位于不同网域，请将服务账号作为 Campaign Manager 360 用户进行实施。这样，您就可以通过在每个账号上分别创建新的用户个人资料并将其全部与一个服务账号关联，从而连接到归不同代理机构拥有的多个账号。这是通过 Campaign Manager 360 使用服务账号的首选方式。
- 如果您的用户位于您拥有的单个网域，请实施全网域委托。在这种情况下，您必须拥有一个使用 G Suite 注册的网域的管理员权限。如需 G Suite 和 / 或网域配置方面的帮助，请参阅 G Suite 支持页面。
前提条件
要将服务账号作为 Campaign Manager 360 用户进行实施，请选择 Campaign Manager 360 用户标签页。要实施全网域委派，请选择下面的委派标签。
<ph type="x-smartling-placeholder">您必须有权访问某个已启用 API 访问权限的 Campaign Manager 360 账号。
- 您必须有权访问某个已启用 API 访问权限的 Campaign Manager 360 账号。
- 您必须拥有对某个使用 G Suite 注册的网域的管理员权限。
- 您必须将 Campaign Manager 360 用户个人资料关联到使用 G Suite 注册的网域中的一个或多个账号。无法使用与其他网域（例如 gmail.com）中的账号关联的用户个人资料。
配置和使用服务账号
若要以 Campaign Manager 360 用户的身份使用服务账号，请选择 Campaign Manager 360 用户标签页。要实施全网域委派，请选择下面的委派标签。
<ph type="x-smartling-placeholder">- 在 Google API 控制台中生成服务账号密钥。
注意：请务必妥善保护相关的密钥文件（该文件会授权服务账号访问其已获得授权的 Google 服务）。由于 G Suite 的网域级控制机制会授予服务账号模拟网域中任何用户的权限，因此这一点对于全网域授权流程尤为重要。另外，最好让每个服务账号仅能访问一个 Google API（使用下一步骤中介绍的“范围”字段）。这是一种预防性措施，可在服务账号的密钥文件被盗时减少攻击者可以访问的数据量。 - 将全网域权限委托给该服务账号，以使其可模拟您网域内的用户。当系统提示时，请提供以下 API 范围：
范围 含义 https://www.googleapis.com/auth/dfatrafficking对 Campaign Manager 360 广告投放管理的读/写权限。 https://www.googleapis.com/auth/dfareporting对 Campaign Manager 360 报告的读/写权限。 https://www.googleapis.com/auth/ddmconversions对 Campaign Manager 360 线下转化的读/写权限。 - 使用您新创建的服务账号在您的应用中实现服务器到服务器 OAuth 2.0 流程。如需了解详情，请参阅示例部分。请记住，您需要提供一个账号以供模拟，并且该账号必须属于在上一步中您的服务账号被授予全网域权限的网域。
如需 G Suite 和 / 或网域配置方面的帮助，请参阅 G Suite 支持页面。
