# WhatsApp — Get contact info

Automatically get contact info on web.whatsapp.com. Open a chat by exact name and read its Contact-info panel: phone number, About text, shared media/links/docs count, and number of groups in common. For a 1:1 contact (for groups, use get_group_members). If the browser isn't linked to WhatsApp, it says so straight away instead of waiting for a chat list that will never load.
