This wikiHow teaches you how to accept an invitation link to join a WhatsApp group chat on Android.
Step 1. Open the invitation link you received
You can receive an invitation link in a text message, email, or in a personal instant message. Group admins can copy and paste the invite link anywhere to add new members.
Step 2. Click on the invite link
WhatsApp Messenger will open automatically and a pop-up window will appear on your screen.
Step #3. Note the group name
The name of the group conversation appears at the top of the invitation pop-up. If a group photo has been set up by the group admins, you will also see it next to the group name in the top left corner of the popup.
Step #4. Note the creator of the group
If you're not sure who invited you to this group chat, check out the group creator's name below the group name. The invite will indicate the name of the group creator followed by "Group created by" at the top of the pop-up window.
Step 5. Check the list of group members
In the invitation pop-up, all current members of the group will be listed under Attendees. Here you may find people you know. In addition, the list can give you an idea of why you received an invite to the group.
Step 6. Tap JOIN
It's the green button in the bottom right corner of your screen. You will be automatically added to the group conversation as a new member. You can immediately start sending messages, images and documents to the group chat.
