{
"description": "The integration mimics the back office e-commerce order processing. The request is expected to contain order with one or more line items as json object with sku, quantity, price, vendor etc. If the total price of the order goes beyond $100 then there will be an email sent to approve the order else the order will be processed successfully. For all the items which have vendor as external, there will be an external order created by making a rest call to the external server. The response of the integration will be total order value, filtered list of external items and list of http response status received for each rest call made per external line_item.",

集成流程示例
下图显示了此集成代码示例的集成编辑器布局示例。
上传并运行示例集成
如需上传并运行示例集成，请按以下步骤操作：
- 将集成示例保存为系统上的 .json 文件。
- 在 Google Cloud 控制台中，前往 Application Integration 页面。
- 在导航菜单中，点击集成。随即会出现集成页面。
- 选择现有集成，或通过点击创建集成来创建新的集成。
要创建新的集成，请执行以下操作：
- 在创建 Integrations对话框中输入名称和说明。
- 为集成选择一个区域。
- 为集成选择服务账号。您随时可以在集成工具栏的 info 集成摘要窗格中更改或更新集成的服务账号详细信息。
- 点击创建。
这将在集成编辑器中打开集成。
- 在集成编辑器中，点击 publish“上传/下载”菜单，然后选择上传集成。
- 在文件浏览器对话框中，选择您在第 1 步中保存的文件，然后点击 Open。
系统会使用上传的文件创建新版本的集成。
- 在集成编辑器中，点击测试。
- 点击测试集成。此时系统会运行集成，并在测试集成窗格中显示执行结果。
