为什么 WhatsApp Flow 模板下拉列表显示静态值，尽管动态数据集成？

Question

我使用模板创建了 WhatsApp Flows，它只包含一个下拉列表，这里用户需要在下拉列表中选择人员，如果我使用 Flow Builder 中的 JSON，它就可以工作，但如果我将其更改为动态值，则不会发生任何变化它正在预览静态值（创建模板时附带的数据）

代码出了什么问题？如何修改 JSON 并应用自定义数据？

Answer 1

但是如果我将其更改为动态值，则它不会发生任何变化 预览静态值

您在这里具体改变了什么？

• 您是否在预览部分选择了“交互式预览”，这将开始与您提供的 URL 进行数据交换。
• 如果是，您的服务器上是否收到 API 调用，您是否看到任何错误？
