Building a Customer Support Ticket System with n8n

In today's customer-centric world, providing timely and effective support is crucial for business success. With n8n, you can build a custom support ticket system that aggregates requests from multiple channels, automates responses, and ensures every customer query is handled efficiently. This guide will walk you through creating a comprehensive support system without expensive software.

Why Build a Custom Support System with n8n?

• Unified Inbox: Aggregate support requests from email, web forms, and social media
• Automated Triage: Automatically categorize and prioritize incoming tickets
• Consistent Responses: Ensure every customer receives timely and accurate information
• No Vendor Lock-in: Own your customer data and workflow
• Customizable: Tailor the system to your specific business needs
• Cost-Effective: Avoid expensive helpdesk software subscriptions

Prerequisites

Before we begin, ensure you have:

1. An n8n instance (cloud or self-hosted)
2. Access to your support channels (email, web form, etc.)
3. A database or spreadsheet to store tickets (we'll use Airtable)
4. (Optional) Communication tools like Slack for notifications

Step 1: Setting Up Your Ticket Database

Using Airtable (Recommended)

1. Create a new Airtable base with these fields:

   • Ticket ID (Auto-number)
   • Customer Name (Single line text)
   • Email (Email)
   • Subject (Single line text)
   • Description (Long text)
   • Status (Single select: New, In Progress, Waiting on Customer, Resolved)
   • Priority (Single select: Low, Medium, High, Urgent)
   • Category (Single select: Billing, Technical, Account, General)
   • Source (Single select: Email, Web Form, Social Media, Phone)
   • Assigned To (Single select: Team members)
   • Created At (Date with time)
   • Updated At (Date with time)
   • First Response Time (Date with time)
   • Resolution Time (Date with time)
   • Tags (Multiple select)

2. Create views:

   • All Tickets
   • Unassigned Tickets
   • My Open Tickets
   • High Priority
   • Overdue

Step 2: Creating the n8n Workflow

1. Webhook Endpoint for Ticket Creation

1. Add a "Webhook" node
2. Set the HTTP method to POST
3. Copy the webhook URL (you'll need this later)
4. Set up basic authentication if needed

2. Parse Incoming Requests

Add a "Function" node to standardize the incoming data:

// Parse the webhook payload
const payload = items[0].json;

// Extract common fields (adjust based on your form/API)
const ticket = {
    customerName: payload.name || payload.customerName || 'Unknown',
    email: payload.email || '',
    subject: payload.subject || 'No Subject',
    description: payload.message || payload.description || '',
    source: payload.source || 'Web Form',
    category: payload.category || 'General',
    priority: determinePriority(payload),
    status: 'New',
    tags: [],
    createdAt: new Date().toISOString(),
    metadata: JSON.stringify(payload) // Store original payload
};

// Helper function to determine priority
function determinePriority(payload) {
    if (payload.priority) return payload.priority;
    if (payload.subject?.toLowerCase().includes('urgent')) return 'High';
    return 'Medium';
}

// Add tags based on content
if (ticket.description.toLowerCase().includes('refund') || 
    ticket.subject.toLowerCase().includes('refund')) {
    ticket.tags.push('billing', 'refund');
}

return {
    json: ticket
};

3. Check for Duplicate Tickets

1. Add an "Airtable" node
2. Configure to search for similar tickets
3. Set up a query to find open tickets from the same email

4. Create or Update Ticket in Airtable

1. Add an "Airtable" node
2. Set to "Create a Record"
3. Map the fields from the function node
4. Configure the node to handle both new and existing tickets

5. Send Acknowledgment Email

1. Add a "Gmail" or "SendGrid" node
2. Create a template with placeholders:

   Hi {{customerName}},
   
   Thank you for contacting support. We've received your request (#{{ticketId}}) and will get back to you shortly.
   
   Subject: {{subject}}
   Description: {{description}}
   
   Best regards,
   Support Team
   

3. Map the fields from previous nodes

6. Notify Support Team

1. Add a "Slack" node
2. Configure to post to your support channel
3. Format the message with ticket details and a link to Airtable

7. Set Up Escalation Rules

Add a "Function" node to handle escalations:

const ticket = items[0].json;
const now = new Date();
const createdAt = new Date(ticket.createdAt);
const hoursSinceCreation = (now - createdAt) / (1000 * 60 * 60);

// Escalation rules
if (ticket.status === 'New' && hoursSinceCreation > 4) {
    return [{
        json: {
            ...ticket,
            priority: 'High',
            tags: [...(ticket.tags || []), 'escalated']
        }
    }];
}

// No escalation needed
return [];

Step 3: Adding More Channels

Email Support

1. Add an "IMAP Email" node
2. Configure with your email server settings
3. Set up a filter to process only unread messages
4. Parse email content and create tickets

Social Media Monitoring

1. Add a "Twitter" or "Facebook" node
2. Set up to monitor mentions/DMs
3. Extract relevant information and create tickets

Web Form Integration

1. Create a web form (e.g., using Typeform or Google Forms)
2. Send form submissions to your webhook URL
3. Process as shown in the main workflow

Step 4: Automating Common Responses

1. Create a Knowledge Base

1. Store common questions and answers in Airtable
2. Add a search function to match incoming tickets with solutions

2. Auto-Respond to Common Queries

Add a "Function" node to detect and respond to common questions:

const ticket = items[0].json;
const commonQuestions = [
    {
        keywords: ['password', 'reset', 'forgot'],
        response: 'You can reset your password by visiting: https://example.com/reset-password'
    },
    {
        keywords: ['billing', 'invoice', 'payment'],
        response: 'For billing inquiries, please visit our billing portal: https://example.com/billing'
    }
    // Add more as needed
];

// Check if the ticket matches any common questions
for (const q of commonQuestions) {
    const hasKeyword = q.keywords.some(keyword => 
        ticket.description.toLowerCase().includes(keyword) ||
        ticket.subject.toLowerCase().includes(keyword)
    );
    
    if (hasKeyword) {
        return [{
            json: {
                ...ticket,
                autoResponse: q.response,
                status: 'Waiting on Customer',
                tags: [...(ticket.tags || []), 'auto-responded']
            }
        }];
    }
}

return [{
    json: ticket
}];

3. Send Automated Responses

1. Add an "Email" node after the function
2. Configure to send the auto-response if available
3. Update ticket status in Airtable

Step 5: Analytics and Reporting

1. Daily Summary Report

1. Add a "Schedule Trigger" node (daily at 8 AM)

2. Add an "Airtable" node to fetch yesterday's tickets

3. Add a "Function" node to calculate metrics:

   const tickets = items[0].json;
   
   const stats = {
       date: new Date().toISOString().split('T')[0],
       totalTickets: tickets.length,
       newTickets: tickets.filter(t => t.status === 'New').length,
       resolvedTickets: tickets.filter(t => t.status === 'Resolved').length,
       averageResponseTime: calculateAverageResponseTime(tickets),
       byCategory: groupByCategory(tickets),
       byPriority: groupByPriority(tickets)
   };
   
   function calculateAverageResponseTime(tickets) {
       const resolvedTickets = tickets.filter(t => t.firstResponseTime && t.createdAt);
       if (resolvedTickets.length === 0) return 0;
       
       const totalTime = resolvedTickets.reduce((sum, ticket) => {
           const responseTime = new Date(ticket.firstResponseTime) - new Date(ticket.createdAt);
           return sum + responseTime;
       }, 0);
       
       return Math.round(totalTime / (resolvedTickets.length * 60000)); // in minutes
   }
   
   function groupByCategory(tickets) {
       return tickets.reduce((acc, ticket) => {
           const category = ticket.category || 'Uncategorized';
           acc[category] = (acc[category] || 0) + 1;
           return acc;
       }, {});
   }
   
   function groupByPriority(tickets) {
       return tickets.reduce((acc, ticket) => {
           const priority = ticket.priority || 'Medium';
           acc[priority] = (acc[priority] || 0) + 1;
           return acc;
       }, {});
   }
   
   return [{
       json: stats
   }];
   

4. Add an "Email" node to send the report
