Here’s how you can integrate them with Node.js using Axios.

​
Step 1: Install Axios

Ensure you have Node.js installed on your system. Navigate to your project directory and install Axios using the following command: 
npm install axios

​
Step 2: Get Your Proxy Credentials

Log in to the Massive dashboard and navigate to the Profile section to find your username, password, and proxy domain. Your proxy URL should follow this format: 
https://<YOUR_USERNAME>:<YOUR_PASSWORD>@network.joinmassive.com:65535
Replace <YOUR_USERNAME> and <YOUR_PASSWORD> with your Massive credentials.

​
Step 3: Make Requests with Massive Residential Proxies

Here’s an example of using Axios with Massive proxies to send a request to httpbin.io/ip, which returns the IP address used for the request. 
const axios = require('axios');

// Proxy credentials
const proxy = {
    protocol: 'https',
    host: 'network.joinmassive.com',
    port: '65535',
    auth: {
        username: '<YOUR_PROXY_USERNAME>',
        password: '<YOUR_PROXY_PASSWORD>'
    }
};

// Target URL
const targetURL = 'https://httpbin.io/ip';

// Axios instance with SSL verification disabled
const axiosInstance = axios.create({
    proxy: proxy,
    httpsAgent: new (require('https').Agent)({
        rejectUnauthorized: false // Disable SSL verification
    })
});

// Make the request
axiosInstance.get(targetURL)
    .then(response => {
        console.log('Your IP Address:', response.data);
    })
    .catch(error => {
        console.error('Error:', error.message);
    });

Troubleshooting Common Errors

Here are some common issues and their solutions:

​
1. Invalid Proxy Credentials

  • If you see a 407 Proxy Authentication Required or 401 Unauthorized error, ensure your username and password in the auth section match the credentials in the Massive dashboard.

​
2. Outdated Axios Version

  • Older Axios versions might not support all proxy configurations. Update Axios to the latest version using: npm install axios@latest

​
3. Connection Refused or Blocked

  • Verify that you’re using the correct protocol (http or https) and port (65534 or 65535).
  • Check if the target website is blocking proxies. Some websites implement advanced anti-bot mechanisms.

​
4. Invalid Proxy URL Format

  • The proxy URL must be correctly formatted: <http://username:password@proxy-host>:port
  • Ensure no component is missing or incorrectly configured.

​
5. IP Rotation Issues

If IPs are not rotating as expected, check the Sticky TTL settings on Massive. Lower the TTL value to rotate IPs more frequently.
