Facebook Marketing API some field are not shown

Question

I have a development level access to Marketing API and it looks like I cannot read some fields of specific objects.

For example I try the following call:

You can see that promoted_object, link_url and object_url are not displayed in the result. And I should have one of those three value as the Ads was ad to promote "web site click".

Is it a bug or a limitation of the development acces or I am doing something wrong?

确实并非所有应用都能读取所有字段，但在上述情况下，很可能这些字段在该对象上为空，因此不会在响应中返回。

例如，广告集级别上需要提升对象，但是您尝试阅读的广告集可能是非常旧的，因此没有指定。

对于广告素材字段，并非所有广告素材都具有这些字段，如果它们为空，则不会在响应中返回。您应该检查promote_story_id，看看它是否包含您要查找的内容。
