Successful Projects: Payment Gateway Integration & WordPress Security Case Studies

Last updated: 03/Jul/2025

As a WordPress developer and security expert, I’ve helped individuals and businesses worldwide securely collect payments online — even in countries where platforms like Stripe or PayPal aren’t available. Here’s a closer look at real-world projects and demos that show exactly how I can help you, too.

Project #1: Stripe Checkout Integration for WordPress (Test Mode Demo)

Client Location: Bangladesh (Test Project)
Platform: WordPress + WooCommerce
Service Provided: Stripe Payment Gateway Integration

Problem:

The client needed to integrate Stripe checkout on their WordPress site to accept card payments. Stripe isn’t officially supported in Bangladesh, so a test mode demo was essential for client confidence and future investor pitching.

Solution:

  • Installed WooCommerce + Stripe Gateway Plugin
  • Enabled Stripe Test Mode
  • Created a $1 dummy product to simulate real transactions
  • Used Stripe test cards to demonstrate a working checkout
  • Added a custom “Stripe Demo” page for client testing

Result:

The client now has a fully working demo payment button, which builds trust with their own clients and investors. Stripe Test Mode ensures no real transactions happen but shows the full flow — securely and professionally.

Project #2: PayPal Smart Button Integration for Services Site

Client Location: USA
Platform: WordPress (Elementor-based)
Service Provided: PayPal REST API & Smart Button Setup

Problem:

The client wanted a PayPal Smart Button on their site to accept one-time and recurring payments without redirecting users to external pages.

Solution:

  • Set up PayPal developer sandbox
  • Integrated the Smart Button using client ID + secret
  • Configured it for both desktop and mobile views
  • Connected with Elementor’s HTML widget for a seamless design
  • Created a guide for switching to live mode after testing

Result:

The client now receives payments directly from their service page with full PayPal integration. The button supports both subscriptions and one-time payments — globally.

Project #3: NOWPayments Integration for Crypto Payments

Client Location: Nigeria
Platform: WordPress
Service Provided: Crypto Payment Gateway (BTC, ETH, USDT, TRX)

Problem:

Client wanted to accept crypto payments securely without using traditional banks or PayPal. They needed a lightweight solution that doesn’t require KYC or complex setup.

Solution:

  • Registered and configured NOWPayments.io
  • Integrated wallet addresses for BTC, ETH, USDT (TRC-20)
  • Embedded payment widgets and QR codes using their API
  • Added payment success/fail callback functions
  • Ensured privacy-focused, non-custodial transaction handling

Result:

The client can now accept crypto payments globally with no middlemen. Works with MetaMask, Trust Wallet, Binance, and even TronLink — ideal for freelancers and agencies in restricted countries.

Project #4: WordPress Malware Cleanup & Security Hardening

Client Location: UK
Platform: WooCommerce Site
Issue: Redirecting to spam / “Japanese keyword hack”

Problem:

The client’s WooCommerce store was redirecting visitors to a Japanese spam site. Their sales dropped to zero, Google blacklisted the domain, and they couldn’t access wp-admin.

Solution:

  • Cleaned infected PHP files (like functions.php, index.php, etc.)
  • Removed obfuscated JavaScript and base64 malware injections
  • Restored core files and reinstalled WordPress safely
  • Scanned and cleaned the database
  • Installed a firewall and login protection
  • Submitted the site to Google Search Console for review

Result:

Site was removed from Google’s blacklist within 72 hours. The client regained full control, improved SEO rankings, and added DDoS protection via Cloudflare.
