Facebook 是否可以从广告对象获取leadgen表单（与广告相关）？

在Business Manager上，每个Facebook Lead广告都与leadgen表单相关联（每当我创建广告时，我也会为其创建一个新表单）。因此，应该可以检索附加到广告的leadgen表单

我知道我可以通过图形链接和页面标记获得所有leadgen表单，但这还不够，因为无法确定哪个表单连接到哪个广告

也就是说，以下是我通过查询广告账户中的广告得到的回复：

这是我的广告目标，从中我可以得到很多东西，广告创意，广告账户，广告活动，广告等等。。。如果我能从其中的某个地方获得leadgen表单链接或ID，那就太好了

最让我困惑的是，我认为上面响应中的leadgen数组就是我需要的表单ID，但对于我查询的每个广告对象，它似乎都是相同的ID，我甚至不知道它是什么ID（不是表单ID）

非常感谢您的帮助

更新：

在翻阅Facebook寻找无关内容时，我发现：

$ad = new Ad(<AD_ID>);
$leads = $ad->getLeads();

---

然而，我得到了上面的每个广告字段，但是我没有从lead对象中得到任何字段

似乎除了上面提到的

getLeads（）

方法之外，从广告中获得leadgen表单是没有办法的；这很好，除非它只会返回一些东西，如果有线索的形式。如果没有任何线索（如果活动尚未启动，通常不会有线索，等等）。。。目前还没有办法确定哪种表单通过API连接到广告
