Question

Facebook

Hello. Tell me how you can count the number of likes under a post using the Facebook API. Interested in information on "Like" and "Super"

Answer 1

This is done through insights and is only available for posts on pages.
Plus, you'll need to get approval from Facebook to use read_insights.
Insights are available only for pages/posts owned by the user, for example, he must have some kind of role on the page.
