Case Study: Junk A Clunker

Industry: Automotive Services
Services Delivered: Custom WordPress plugin, API integrations (Peddle, NHTSA), user experience improvements

Turning Manual Processes Into Seamless Automation

Junk A Clunker connects users looking to sell junk cars with offers from Peddle — a service that buys vehicles and arranges pickups. But while the front end looked functional, the backend was another story. Every enquiry had to be processed manually by the client, slowing things down and leaving too much room for error.

They needed a faster, smoother way to handle requests — and that meant getting the website talking directly to Peddle’s systems.

What They Needed

  • A fully automated way to connect with Peddle and handle incoming car sale requests
  • Clean data handling for multiple response types and user inputs
  • A smoother, more user-friendly form experience
  • A way to decode VIN numbers automatically to prefill vehicle details

How I Helped

I developed a bespoke WordPress plugin that completely automated the Peddle integration — turning a tedious, manual workflow into a streamlined, API-driven process.

Deep Integration With the Peddle API

The core of the project was building a plugin that could handle multi-stage interactions with the Peddle API — from initial data submission to various follow-up responses. Each stage had to be parsed and processed correctly, accounting for different response types and possible user flows.

Smart Data Structures

I used custom post types within WordPress to log and manage each step in the process, ensuring everything was stored in a structured, traceable way. This made it easier for the client to track submissions and debug if needed.

Built-In Flexibility

Users often need to leave and come back — so I made sure the form could handle that. Progress is saved between stages, and users can return to finish submitting at their convenience.

VIN Decoding Integration

To make things even easier, I added integration with the NHTSA API to decode VINs. Users just pop in their VIN, and the form auto-fills vehicle details — reducing errors and saving time.

Results

The new plugin transformed how Junk A Clunker operates:

  • Manual processing eliminated — saving hours of admin time
  • Users get a clean, fast, and flexible experience
  • Data flows securely and reliably between the site and Peddle
  • Built to be maintainable, with structured data storage and future extensibility

Why It Worked

This project combined practical automation with thoughtful UX. By connecting directly to the right APIs and handling the messy bits behind the scenes, the site now delivers a smooth experience for both users and the business. It’s a great example of how small dev changes can have a big operational impact.
