Job Title: Software Developer Required – Parking System API Integration for Pay-on-Foot Machine Project Description: We are looking for an experienced software developer to support integration between an existing Pay-on-Foot parking payment machine and a “Find My Car” system. The Pay-on-Foot machine is currently operating on a Windows 10 PC, connected to the parking network and linked with an SQL database. The machine has a touchscreen interface. Required Scope of Work: The developer will be required to create or modify the software interface so that the Pay-on-Foot machine can: 1. Send an API request to the “Find My Car” system. 2. Retrieve the car parking location details. 3. Retrieve and display the vehicle image on the touchscreen. 4. Retrieve or calculate the parking fee amount. 5. Display the parking charge clearly on the screen. 6. Allow the customer to press a “Pay” button. 7. Once the customer presses “Pay,” the existing payment system will continue the remaining payment process. Developer Requirements: The freelancer should have experience with: * Windows desktop application development * API integration * SQL database connection and queries * Touchscreen user interface design * Parking management systems or payment systems preferred * C#, .NET, Python, or similar suitable technologies * Ability to work with existing software and hardware environment Expected Deliverables: * Working software/module integrated with the Pay-on-Foot machine * API request and response handling * Display of car location, image, and parking charge * Touchscreen-friendly interface * Testing on site or remotely with our technical team * Basic documentation for installation and operation Important Note: The payment processing itself is not part of this scope. The developer only needs to prepare the screen and logic up to the point where the customer presses the “Pay” button. The existing parking/payment system will handle the remaining payment steps. Please include in your offer: * Similar experience * Proposed technology * Estimated delivery time * Total cost * Support period after delivery * Any requirements needed from our side, such as API documentation, SQL access, or remote access to the machine.

Hello, I understand you need a Windows desktop module that connects the Pay-on-Foot machine with your Find My Car system. I will build a compact, reliable interface that sends API requests, retrieves location details and vehicle image, computes or fetches the parking fee, and displays it clearly on the touchscreen. The solution will expose a “Pay” action that hands off to your existing payment flow, while handling API calls, SQL data access, and a touch-friendly UI tailored for your machine. My approach is to implement a lightweight .NET/C# component that integrates with your SQL database and the Find My Car API, with robust error handling, logging, and secure data transfer. I’ll deliver a tested module that can be deployed on the Windows 10 PC, with on-site or remote validation alongside your technical team and concise installation/operation docs. I’ll ensure the UI stays clean on a touchscreen and works with your current hardware and network setup. Do you have API documentation and access credentials ready for integration? Best regards,

Hi, This is Elias from Miami. I have checked your project description and understand that you're looking to integrate an API for a pay-on-foot parking machine system. This will likely involve managing transactions and user interactions efficiently. I have experience in API development and backend integration, having worked on similar projects where I built secure and robust solutions for payment systems. To approach this project, I would start by analyzing the existing system requirements and how the API will interact with the pay-on-foot machines. I will ensure that the integration is seamless and adheres to best practices for security and performance. I have a few questions for clarification: Q1 – What specific functionalities do you want the API to support (e.g., payment processing, user management)? Q2 – Are there any existing systems or databases that the API will need to integrate with? Q3 – What is the expected volume of transactions, and do you have scalability requirements in mind? I’d be happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hey, I will build the integration module — API calls to the "Find My Car" system, retrieval of car location and image, fee calculation, and a touchscreen-friendly UI displaying all details with a "Pay" button that hands off to your existing payment flow. I will structure the C#/.NET WPF app to handle API timeouts and image caching locally, so the touchscreen stays responsive even if the network lags briefly. Questions: 1) Do you have the "Find My Car" API documentation ready? 2) Is the current Pay-on-Foot interface a standalone app or browser-based? Looking forward to discussing further.

Hi there To integrate the Pay-on-Foot machine with the “Find My Car” system, the most critical part is inserting the new lookup flow without interfering with the existing payment process. I’ll approach this by building or modifying a Windows-compatible module that sends the plate/ticket query, retrieves location details, vehicle image, and fee amount, then presents everything clearly on the touchscreen before handing control back to the existing Pay button flow. This means I understand how the customer scans or enters details, the system calls the API, displays the car location and charge, and only then continues into the current payment system. My process is simple: first review API docs, SQL access, and machine environment. Then build the integration and touchscreen UI. Finally, test response handling, errors, and handoff to payment. If this aligns with you, let’s discuss in detail via private chat.

Hi I can help build or modify the Pay-on-Foot machine interface so it connects with the “Find My Car” system and displays the required vehicle details before payment. The key technical challenge is integrating the API, SQL data, touchscreen UI, and existing payment handoff without disrupting the current parking payment process. I would recommend C#/.NET for the Windows 10 touchscreen environment, unless the current software stack requires Python or another compatible technology. The module can send the API request, retrieve car location details, fetch and display the vehicle image, query or calculate the parking fee, and show a clear “Pay” action on the screen. Once the customer presses “Pay,” the system can pass control back to the existing payment workflow exactly as required. I can also support SQL queries, API response handling, error messages, timeout handling, image loading, touchscreen-friendly layouts, and remote/on-site testing with your technical team. I have experience with Windows desktop applications, API integrations, database-backed systems, hardware-connected environments, and payment-adjacent workflows. Thanks, Hercules

I’ve integrated Windows-based payment kiosks with external APIs before, including live data display and touchscreen interaction. For your Pay-on-Foot machine, I’ll set up the interface to send requests to the “Find My Car” system and display location, vehicle image, and fees clearly on the screen. Since the machine uses an SQL database, I’ll handle data queries to fetch or calculate parking fees accurately. The interface will have a responsive Pay button that triggers your existing payment flow without disruption. I suggest using C# with .NET for smooth Windows integration and touchscreen support, but I’m open if you prefer Python or another tool. To move forward, could you share the API documentation and details about the current payment software’s integration points? Also, is remote access to the machine available for direct testing? I estimate delivery within 2-3 weeks, including remote testing with your team. I’ll provide clear usage docs and a support period post-deployment to handle any early fixes. Ready to start building this interface to get your system talking seamlessly.
