Set the Facebook account language
Automatically set the Facebook account language on facebook.com. Change the interface language of the signed-in Facebook account, picking it by its native name exactly as Facebook lists it (for example English (US) or Français (France)). Returns the language that was selected before and the one selected now, and fails with the list of available names when the requested one does not exist. The change applies to the whole account, including emails and notifications, until it is changed again.

Get Facebook profile info
Get header and intro info for a Facebook profile or page (pass a URL or a bare id/username). Returns the type (profile or page), the name, friends, likes and follower counts as displayed, mutual friends, and the intro lines — bio plus city, work and education for people, or the description for pages. Counts come back as the strings Facebook shows (e.g. "11 K") and intro lines are returned as they appear, not sorted into city, work or school fields. Works in either the French or the English interface. An id or username Facebook will not serve returns a clear error rather than an empty record.
Find Facebook groups by keyword
Find Facebook groups by keyword with member counts and posting activity, as structured data. Search Facebook groups by keyword. Returns groupId, name, url, privacy, members, postsPerDay. Results are infinite-scroll, capped by limit.
Join Facebook groups automatically
Join Facebook groups automatically from an agent, one group per call, including private groups with entry questions. Join a Facebook group by id/slug. Returns status (joined / pending / already_member) and name. Pending means a private-group request was sent, not membership.
