## Introduction
Customer support teams often face the challenge of efficiently sorting and assigning incoming tickets based on various criteria such as topic, tags, or language. Zendesk’s ticket routing feature simplifies this by automatically directing tickets to the appropriate agents or teams. However, Zendesk can be expensive, especially for startups or growing businesses.
This guide demonstrates how to replace Zendesk’s ticket routing automation using **n8n**, an open-source workflow automation tool. Automating ticket routing using n8n reduces dependency on costly SaaS solutions and offers full customization tailored to your organization’s needs.
Target users benefiting from this automation include customer support managers, automation engineers, and operations specialists in startups or SMBs.
## Tools and Services Integrated
– **n8n**: To build the automation workflow.
– **Email or Ticketing System**: Incoming tickets via email, webhook, or API (e.g., Gmail, or custom ticket systems).
– **Google Sheets (optional)**: To maintain routing rules or lookup tables.
– **Slack (optional)**: For notifications of assigned tickets.
– **Database or CRM (optional)**: For enriched context if available.
In this tutorial, we assume tickets come in via email or API webhook and that routing rules depend on ticket subject, tags, and language.

## Step-by-Step Tutorial
### Step 1: Set Up n8n Environment
– Deploy n8n on your server, cloud VM, or use n8n.cloud.
– Ensure n8n can receive webhook requests or connect to your mailbox.
### Step 2: Define Routing Logic and Criteria
Typically, routing depends on:
– **Topic**: Keywords in the subject or body (e.g., “Billing”, “Technical Issue”).
– **Tags**: Labels or metadata attached to tickets.
– **Language**: Detect customer language from messages.
Maintain these rules either hard-coded in the workflow or in a Google Sheet for dynamic updates.
### Step 3: Create the n8n Workflow
#### 3.1 Trigger Node
– Use **Webhook** node if tickets arrive via an API.
– Use **IMAP Email** node if tickets come in as emails.
This node captures incoming ticket data (subject, body, tags, language).
#### 3.2 Extract Ticket Data
– Use **Function** or **Set** nodes to extract necessary fields:
– Ticket subject
– Ticket body
– Tags (if available)
– Language (detect using Google Translate API or a built-in function)
#### 3.3 Topic and Tag Matching Logic
Implement conditional branching:
– Use **IF** nodes to check if ticket subject/body contains specific keywords.
– Use **Set** nodes or external lookup to identify team or agent aliases.
Example conditional checks:
– If subject contains “Billing” then assign to Billing Team
– Else if tag includes “Urgent” then assign to Senior Agent
#### 3.4 Language Detection (Optional but Recommended)
– Use a **HTTP Request** node to call Google Translate API or another language detector to identify ticket language.
– Route tickets to language-specific teams accordingly.
#### 3.5 Assign Ticket
Depending on your ticketing system:
– Use API nodes or **HTTP Request** nodes to update ticket assignment in your system.
– Alternatively, send an email or Slack notification to the responsible agent/team.
#### 3.6 Notification (Optional)
– Add **Slack** node to notify the assigned team/channel instantly.
– Include ticket details and assignment info.
### Step 4: Error Handling and Robustness
– Use **Error Trigger** node in n8n to catch workflow errors.
– Implement retries on API calls.
– Set up alert notifications (email or Slack) on failure.
– Log all ticket routing decisions in a Google Sheet or database for audit and debugging.
### Step 5: Testing and Validation
– Simulate incoming tickets with various topics/tags/languages.
– Confirm correct assignment.
– Monitor workflow execution in n8n’s editor.
### Step 6: Scaling and Adaptation
– Store routing rules externally (Google Sheets, Airtable) to allow non-technical staff to update rules without editing the workflow.
– Add more sophisticated NLP processing if desired (e.g., integrate OpenAI or other ML models for topic classification).
– Integrate with additional communication channels (e.g., Microsoft Teams, SMS) for notifications.

## Workflow Breakdown – Sample Nodes
1. **Webhook Trigger**: Receives ticket JSON payload.
2. **Function**: Parses subject, body, tags.
3. **HTTP Request (Language Detection)**: Calls language detection API.
4. **IF nodes**: Evaluates routing conditions:
– Matches keywords in subject/body.
– Checks tags.
– Checks language.
5. **Set node**: Sets assignee variables.
6. **HTTP Request (Assign Ticket)**: Calls ticket system API to assign ticket.
7. **Slack Node**: Sends notification to support channel.

## Common Errors and Tips
– **Webhook Authentication**: Secure webhook endpoints with API keys or Basic Auth.
– **API Rate Limits**: Implement throttling in HTTP Request nodes.
– **Language Detection Latency**: Cache language results if tickets from same users.
– **Parsing Issues**: Normalize ticket text (lowercase, trim) before matching.
– **Error Notifications**: Use n8n’s error workflows to get immediately notified of failed runs.

## Summary
Replacing Zendesk’s ticket routing with n8n enables cost-effective, highly customizable ticket assignments based on dynamically defined topics, tags, and languages. Using n8n’s flexible workflow engine, teams can automate routing workflows integrated with multiple communication and ticketing platforms.
This approach grants full control over routing logic, better transparency, and ease of adaptation as business requirements evolve, all while significantly reducing software subscription costs.

## Bonus Tip: Automate Rule Updates
Integrate a **Google Sheets Trigger** node to watch for updates in routing criteria spreadsheets. Whenever rules change, n8n can automatically reload or restart workflows, ensuring that your ticket routing logic stays up to date without manual intervention.
