Slack Channel ID

Right-click your Slack channel → View Channel Details Copy the Channel ID Update it in:

“Send Slack Notification” node “Error – PDF Failed” node “Error – Upload Failed” node

4. Configure Webhook in Support Tool

Activate the workflow in n8n Copy the Webhook URL from the “Webhook – Receive Ticket” node In Zendesk/Freshdesk:

Trigger: “Ticket Status = Resolved” Method: POST Paste the n8n webhook URL Send ticket data as JSON

5. Test the Workflow

Click “Execute Workflow” manually Send a test webhook Verify each step completes successfully Check:

Generated PDF in Google Drive Row entry in Google Sheets Slack notification delivery

How It Works

Webhook Trigger → Receives resolved ticket Data Extraction → Normalizes ticket fields AI Summarization (OpenAI) → Generates structured summary HTML Formatting → Styles and adds branding PDF Conversion (PDFMunk) → Converts HTML → PDF Google Drive Upload → Saves and returns shareable link Sheets Logging → Appends ticket info + PDF link Slack Notification → Notifies team with summary Error Handling → Detects and reports failures Result → Clean, documented ticket case study in minutes

Customization

Branding

Update company name, logo URL, and color scheme in the “Format HTML” node. Default color: #4CAF50 → Replace with your brand color.

AI Prompt Customization

Modify “AI Summarization (OpenAI)” node to add:

Industry-specific terms Additional sections or insights Different summary tone or length

Notification Customization

Add @mentions or emojis in Slack messages for better visibility.

Data Flow

Webhook → Extract Data → AI Summary → Format HTML → Convert to PDF
↓
Download PDF → Upload to Drive → Log in Sheets → Notify Team
↓
Error Handling (if any)

Expected Output

PDF Document Includes:

Branded header with company name/logo Resolution time badge Ticket metadata (ID, priority, customer, agent, etc.) Full AI-generated case study Professional footer with timestamp

Google Sheets Entry:

All ticket info Resolution metrics Direct PDF link Status = “Generated”

Slack Notification:

Summary of ticket Clickable PDF link Timestamp

Performance

Processing Time:** 10–20 seconds/ticket Capacity:** 100+ tickets/day PDF Size:** 50–300 KB

Troubleshooting

Webhook not triggering → Check webhook URL, trigger conditions, and public access. PDF generation fails → Verify HTML syntax and PDFMunk API key. Google Drive upload fails → Re-authenticate credentials or check folder permissions. Slack notification missing → Ensure bot token, scopes, and channel ID are valid. Data extraction errors → Adjust field mappings or inspect payload format.

Best Practices

Test before production rollout Monitor first-week error logs Organize Drive by date/priority Validate Sheets columns Use a dedicated Slack channel Archive old PDFs regularly Review AI summaries weekly Document configuration changes

Security Notes

All credentials stored securely in n8n PDF links are restricted by Drive sharing settings Webhooks use HTTPS for secure data transfer No sensitive info logged in error messages

Future Enhancements

Multi-language summaries Integration with Confluence or Notion Customer satisfaction feedback link ML-based issue categorization Analytics dashboard Weekly email digests Public knowledge base generation
