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).
