# WhatsApp — List communities

Automatically list communities on web.whatsapp.com. List the WhatsApp communities this account belongs to, each with the groups the Communities tab previews for it. Returns every community's name plus its group names, flagging the announcement group and whether WhatsApp is hiding further groups behind its "View all" link — the tab shows only the first few per community, so the group list is a preview rather than full membership. Returns an empty list when the account has no communities, which is a real answer rather than a failure.
