Here’s a sample JavaScript code for integrating with the FraudGuard.io API using Node.js and associated explanation.

This JavaScript code using Node.js performs the following steps:

  1. Sets the FraudGuard.io API credentials (username and password).
  2. Defines the IP address to query.
  3. Constructs the API endpoint URL.
  4. Encodes the credentials using Base64 for basic authentication.
  5. Sets options for the HTTP request, including the Authorization header.
  6. Makes an HTTPS request to the API endpoint using https.request.
  7. Handles the response by concatenating data chunks and logging the response content.
  8. Handles errors that may occur during the request.
const https = require('https');

// FraudGuard.io API credentials
const username = 'username';
const password = 'password';

// IP address to query
const ipAddress = '8.8.8.8';

// API endpoint
const apiUrl = `https://api.fraudguard.io/ip/${ipAddress}`;

// Basic authentication header
const authString = `${username}:${password}`;
const base64AuthString = Buffer.from(authString).toString('base64');
const authHeaderValue = `Basic ${base64AuthString}`;

// Set options for HTTP request
const options = {
  method: 'GET',
  headers: {
    'Authorization': authHeaderValue
  }
};

// Make HTTP request
const req = https.request(apiUrl, options, (res) => {
  let data = '';

  // A chunk of data has been received
  res.on('data', (chunk) => {
    data += chunk;
  });

  // The whole response has been received
  res.on('end', () => {
    console.log(data);
  });
});

// Handle errors
req.on('error', (error) => {
  console.error(error);
});

// End the request
req.end();

Make sure to replace ‘username’ and ‘password’ with your actual API credentials.
