A short guide: how to join a WhatsApp group using an invite link, and what to check before you join.
What is an invite link
A WhatsApp group invite link starts with chat.whatsapp.com and lets you join in one tap, without an admin adding you manually.
Joining steps
Tap the link on the phone where WhatsApp is installed, confirm on the screen that opens, and you are in. If the link opens on a computer, use WhatsApp Web.
What to check first
Make sure the group is relevant, glance at its description and rules, and never share sensitive personal information with unfamiliar groups.
