Does the Facebook graph API, video_insights gives data for crossposted video?

Question

I have linked two pages to have crosspost access. Published a video post(Post11) in Account1 and gave permission for Account2 to crosspost the video. Account2 created a post(Post21) with the same video used in Post11. Got engagements on both the posts. Cannot see any data for Post21(i.e Crossposted video) in graph api, however can see data for Post11(i.e Original video). Is it expected that graph API wont return anything when queried video_insights endpoint for crossposted video ?

Currently, it just returns me this

{
  "data": [
  ]
}

when the query is, https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=910714455761671%2Fvideo_insights&version=v2.8

Yes. Graph API won't return insights for a video unless you have valid permission to read its insights. You can check the permissions required by the Graph API here.

However, you need to know the difference between insights returned from {video_id}/video_insights and {post_id}/insights.

As stated in the documentation, the first one will give you insights for the video as overall (original and crossposted posts) while the second will return data related to the post you are retrieving only.

This means the data you see for Post11 is the data from Post11 and Post21 combined.

In your case, you can use {post_id}/insights to get insights of Post11 alone and then compare the results with the one you got from {video_id}/video_insights to see how Post21 performed. This, of course, if you can't get permission to Account2 which would be so much easier.

Answer 2

Yes. Graph API now returns video_insights results for crossposted videos: https://developers.facebook.com/docs/video-api/guides/crossposting#insights

I can't find any evidence of when this was changed.

I skimmed the changelogs and out-of-cycle logs and didn't find anything.

I've confirmed that video_insights do return for page owned crossposted video ids in the graph explorer.
