Who’s it for
This workflow is ideal for community managers, event organizers, and businesses that regularly manage multiple WhatsApp groups. If you have a growing list of invitation codes stored in Google Sheets, this automation helps you automatically join groups, update statuses, and track results without manual work.
How it works / What it does
The workflow connects Google Sheets with WhatsApp through an automation sequence:
- Reads the list of invitation codes from a Google Sheet.
- Processes the first 50 unused codes per run.
- Validates group links via a Fetch groups node.
- Attempts to join each group using the Join group node.
- Updates the sheet with the join status (success or failure).
- Logs successful joins in a tracking list for easy follow-up.
This ensures a fully automated way to manage WhatsApp group invitations while keeping your data organized in Google Sheets.
How to set up
- Prepare a Google Sheet with invitation codes and a status column.
- Configure the Google Sheets node with read and write access.
- Set up your fetch-groups and join-group credentials.
- Adjust the Schedule Trigger to define how often the workflow should run.
- Test with a few sample codes before scaling.
Requirements
- n8n (self-hosted or cloud).
- Google Sheets API credentials.
- WhatsApp integration (via [Evolution API] or another community node — self-hosted only).
How to customize the workflow
- Change the batch size (default: 50 codes per run).
- Add error handling or retry logic for invalid links.
- Send real-time notifications (Slack, email, or Telegram) after each join.
- Extend your Google Sheet schema with extra details (e.g., group category, campaign, date joined).
