Step 2: Create the Workflow

1. Click "Add Workflow"
2. Add a "Google Sheets" trigger node
3. Configure it to watch your specific spreadsheet
4. Add a "Slack" node
5. Connect the nodes and configure the message

Best Practices

1. Error Handling

   • Always add error handling nodes
   • Set up notifications for failed workflows
   • Use the "Split" node to handle different scenarios

2. Security

   • Keep your credentials secure
   • Use environment variables for sensitive data
   • Regularly update n8n to the latest version

3. Performance

   • Use the "Wait" node for rate-limited APIs
   • Implement pagination for large datasets
   • Cache frequently used data
