To join a WhatsApp group, you generally need an invite link shared by the group admin or a member. Here is how you can join a WhatsApp group using a link:

• Receive the group invite link, which usually looks like chat.whatsapp.com/XYZ where XYZ is a unique code.
• Tap or click on the link. WhatsApp will open and show you the group's name and members.
• Tap the "Join Group" button to become a member and start participating in the group chat.

This method is fast and convenient for joining social, educational, or professional groups

. If you want to find WhatsApp group links to join, there are websites and apps that collect and share active group invite links across many categories like entertainment, sports, jobs, travel, and more. Examples include whtsgrouplink.org and joinnchat.com, which update links regularly to ensure they are active and safe

. To create and share your own WhatsApp group invite link (only group admins can do this):

• Open the WhatsApp group.
• Tap the group name to open group info.
• Select "Invite via link."
• Copy and share the link with people you want to invite.
• You can also reset the link anytime to invalidate the old one and generate a new invite link

When joining groups via links, be cautious about privacy and security, especially if the link is from unknown sources, as all group members can see your phone number

. Additionally, WhatsApp Communities allow users to join groups within a community by browsing groups and tapping "Join group" or "Request to join" if the group is full

. In summary, to join a WhatsApp group:

• Get an invite link from an admin or trusted source.
• Tap the link and confirm joining.
• Use websites or apps to find group links by interest.
• Create your own invite link if you are an admin to add members easily.

This covers how to join WhatsApp groups and find or create invite links effectively.
