Add WhatsApp Group Participants Via Invite Link Using Python

In this tutorial, you can learn how to get a WhatsApp Group invitation link and send it to users allowing them to join your Group using the Wassenger API and Python

Expanding your audience by sending WhatsApp group invite links is highly effective, thanks to WhatsApp’s impressive 98% open rates. Imagine being able to send personalized recommendations, answer common questions, and analyze market trends automatically and instantly.

However, enhanced WhatsApp privacy features now make it difficult to automatically add users to groups if they haven’t saved your number, as their privacy settings may prevent it.

The good news is there’s a solution covered in this tutorial: you can send a private message to specific users with the group invite link, enabling them to join the group.

To achieve this, you’ll perform two tasks using the API:

1. Obtain the WhatsApp group invitation link: You must be a participant with invite permissions in the target group. 2. Send the group invite link via private WhatsApp message to the user.
