Who's it for

This template is perfect for community managers, business owners, and WhatsApp group administrators who want to create a welcoming experience for new members. Whether you're running a support group, managing a business community, or moderating a hobby group, this automation ensures every new member feels valued from the moment they join.

How it works

The workflow automatically detects when someone joins your WhatsApp group and sends them a personalized welcome message directly to their private chat. It uses Evolution API to interface with WhatsApp Business and includes a natural delay to make the interaction feel more human. The entire process is hands-off once configured, ensuring consistent engagement with new members 24/7.

What it does

  1. Monitors group activity - Receives real-time notifications when members join or leave
  2. Filters for your specific group - Ensures messages are only sent for your designated group
  3. Validates new joins - Confirms the event is a member joining (not leaving)
  4. Adds natural timing - Waits a customizable period before sending the message
  5. Sends private welcome - Delivers your welcome message directly to the new member's chat

Requirements

  • Evolution API instance (self-hosted or cloud service)
  • WhatsApp Business account connected to Evolution API
  • Group admin permissions for the WhatsApp group
  • n8n instance (self-hosted or cloud)

How to set up

  1. Import the workflow into your n8n instance

  2. Configure the Set Variables node with:

    • Your WhatsApp group ID (format: [email protected])
    • Evolution API key
    • Instance name from Evolution API
    • Evolution API URL
    • Custom welcome message
    • Delay time in minutes

  3. Copy the webhook URL from the Webhook node

  4. Configure Evolution API to send group notifications to your webhook URL

  5. Test the workflow by having someone join your group

  6. Activate the workflow for continuous operation

How to customize the workflow

  • Welcome message: Edit the message in the Set Variables node to match your group's tone
  • Timing: Adjust the wait time to send messages immediately or after several minutes
  • Multiple groups: Duplicate the workflow and change the group ID for each group
  • Rich media: Extend the HTTP Request node to send images or documents with the welcome
  • Conditional messages: Add IF nodes to send different messages based on time of day or member count
  • Follow-up sequence: Chain additional HTTP Request nodes to create a welcome series
