Customer Support Email Ticket Handling with Slack Alerts and Google Sheets Logging

This workflow automates customer support ticket creation, triage, and notifications, integrating with Slack, email, and Google Sheets. Key nodes include Webhook for ticket submission, Schedule Trigger for daily reports, Condition for security and input validation, Set for data sanitization, Switch for severity routing, Slack for critical alerts, Email Send for notifications, Google Sheets for logging, and Webhook Response for output. It ensures GDPR-compliant ticket management. To set up, download n8n from n8n.io for self-hosting or sign up at cloud.n8n.io. Obtain a Slack API token from api.slack.com/apps under Your Apps > Create New App > OAuth & Permissions (Bot User OAuth Token). Configure SMTP credentials for email (e.g., Gmail SMTP: smtp.gmail.com, port 587) via your email provider’s settings. Get Google Sheets API credentials from console.cloud.google.com under APIs & Services > Credentials (OAuth 2.0 Client ID). In n8n, add these under Credentials > Add Credential > Slack API, SMTP, and Google Sheets OAuth2 API. Import the workflow JSON via Workflows > Import. Configure the Webhook node (path: /customer-support-ticket-automation, method: POST) with CORS headers (Access-Control-Allow-Origin: *). Use ngrok for local webhook testing (e.g., ngrok http 5678). Set the Schedule Trigger to a cron expression (e.g., 0 9 * * * for 9 AM UTC). Ensure HTTPS in the Condition node for secure transmission. Test by sending a POST request to the webhook with JSON (e.g., {ticketTitle: 'Login Issue', ticketDescription: 'Cannot access account', customerEmail: 'user@example.com', severity: 'high'}). Include headers (x-api-key, x-support-authorization). Validate output in the Set node for devHubConnectSupportResponse (e.g., success: true, ticketInformation.ticketId). Handle errors like invalid API keys (401 response with 'SUPPORT_SECURITY_VALIDATION_FAILED') or missing ticket fields (400 response with 'INVALID_SUPPORT_INPUT'). For issues, verify HTTPS, credential accuracy, and the Google Sheets document ID. Deploy by saving and enabling the workflow. Test with a sample ticket to confirm Slack/email notifications and Google Sheets logging. Check Webhook Response for supportOperationResults (e.g., ticketStatus: 'open'). If integrations fail, verify node connections and credentials in n8n’s editor.
