The Pages API allows apps to access and update a Facebook Page's settings and content, create and get Posts, get Comments on Page owned content, get Page insights, update actions that Users are able to perform on a Page, and much more.
Beginning October 2, 2020, we will begin migrating select Facebook Pages to the New Page Experience. The New Page Experience API allows your app to manage the New Page Experience for Pages to drive public content, engagement, and discourse on your Facebook Page.
Visit the New Page Experience Page Category Reference to see if your Page will be migrated.
Visit the New Page Experience Endpoints Reference for accessible endpoints.
