Proxy Integration with n8n: Automate Web Workflows Without Code

n8n is an open-source workflow automation platform that lets you connect APIs, scrape websites, and process data — all without writing code. By integrating ZentisLabs proxies with n8n, you can build automated data collection workflows that rotate IPs, handle geo-targeting, and scale without getting blocked.

What Is n8n?

n8n (pronounced "nodemation") is a workflow automation tool similar to Zapier or Make, but self-hosted and open-source. It has 400+ integrations and supports custom HTTP requests, JavaScript code nodes, and webhook triggers. You can deploy it on a ZentisLabs VPS for full control.

Setting Up n8n with Docker

# docker-compose.yml
version: "3.8"
services:
  n8n:
    image: n8nio/n8n:latest
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_USER=admin
      - N8N_BASIC_AUTH_PASSWORD=your-secure-password
      - GENERIC_TIMEZONE=UTC
    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  n8n_data:

docker compose up -d
# Access n8n at http://your-server:5678

Proxied HTTP Requests in n8n

The simplest integration is using the HTTP Request node with ZentisLabs as a proxy. In the node settings:

• Set URL to your target (e.g., https://api.example.com/data)
• Under Options → Proxy, set: http://USER:PASS@gate.zentislabs.com:7777
• Each execution gets a different IP automatically

Example: Price Monitoring Workflow

Here's a complete n8n workflow that monitors competitor prices daily:

• Trigger: Cron node → runs daily at 9 AM
• Fetch: HTTP Request node → hits competitor pricing page through ZentisLabs proxy
• Extract: HTML Extract node → pulls price values from the page
• Compare: Code node → compares with yesterday's prices from a Google Sheet
• Alert: Slack node → sends a message if prices changed by more than 5%
• Store: Google Sheets node → appends today's prices to the tracking sheet

Using the Code Node for Advanced Proxy Logic

For geo-targeted requests or custom retry logic, use n8n's Code node:

// n8n Code Node - Fetch with geo-targeting
const countries = ['us', 'gb', 'de', 'jp'];
const results = [];

for (const country of countries) {
  const proxy = `http://USER:PASS_country-${country}@gate.zentislabs.com:7777`;
  
  const response = await this.helpers.httpRequest({
    url: 'https://target-site.com/pricing',
    proxy: proxy,
    timeout: 15000,
  });
  
  results.push({
    json: {
      country,
      html: response,
      timestamp: new Date().toISOString(),
    }
  });
}

return results;

More Workflow Ideas

• SEO rank tracking: Daily Google SERP checks across multiple locations
• Review monitoring: Scrape product reviews from Amazon, G2, or Trustpilot through proxies
• Stock monitoring: Check product availability across e-commerce sites
• Content change detection: Monitor competitor blogs, pricing pages, or job postings
• Ad verification: Check that your ads appear correctly in different markets
