Kaufland API Integration Module
Budget: €250 – €750 EUR
The goal of this project is to develop a self-contained Kaufland API Integration Module for middleware, which will include the following components:
KauflandConnector: A C# class for seamless interaction with the Kaufland Seller API.
Graphical User Interface (GUI): A configuration interface to allow users to manage their Kaufland marketplace account settings.
Key Features & Deliverables:
1. Backend Class: KauflandConnector
Responsibilities:
Establish a connection with the Kaufland Seller API using HTTP headers for secure authentication (apiKey and apiSecret).
Provide methods for:
SyncProducts: Retrieve and synchronize product data between the middleware system and Kaufland.
SyncOrders: Fetch and synchronize order details.
SyncShippingStatus: Submit shipping updates to Kaufland.
TestConnection: Verify the connectivity and authentication to the Kaufland API.
Architecture:
Inherits from an abstract base class MarketplaceConnector to ensure flexibility and maintainability across various marketplace integrations.
No direct database access; all data must be processed by the Windows Service layer.
Employs standardized DTOs (Data Transfer Objects) such as ProductDto, OrderDto, and ShippingUpdateDto for consistent data handling.
Technology Stack:
Target Framework: .NET 9 (net9.0)
Programming Language: C# 13
API Communication: Utilizes HttpClient for RESTful API interactions and data retrieval.
JSON Parsing: Preferably System.Text.Json, with support for Newtonsoft.Json if needed.
Logging: Error handling and logging should be communicated back to the caller, without the use of file or database logging.
2. GUI Component: Kaufland Configuration Panel
The GUI will be developed in WPF or modern WinForms (for .NET 9) and integrated into the middleware settings panel. It will allow users to configure their Kaufland marketplace account settings.
Required Configuration Fields:
API Key and API Secret for Kaufland API access.
Sync Interval: Set the frequency (in minutes) for synchronizing data.
Account Status: Enable or disable the account integration.
Price Markup: Specify the percentage markup for products.
Delivery Time: Define default delivery time (in days).
Default Shipping Provider: Choose the preferred shipping provider (e.g., DHL, UPS).
Stock Management: Optional minimum and maximum stock thresholds.
Connection Test: A button to test API connection.
Save Settings: Option to save configuration preferences.
3. Optional Stock Management Logic
In the SyncProducts method, the following stock filtering logic should be implemented:
MinStock Filter: Exclude products whose stock falls below the specified minimum threshold.
MaxStock Filter: Adjust products whose stock exceeds the maximum allowed stock to the configured maximum value.
Project Deliverables
KauflandConnector.cs: A C# class that implements the Kaufland API integration.
Models/: Optional internal DTOs for standardizing data (e.g., ProductDto, OrderDto, ShippingUpdateDto).
Api/KauflandApiClient.cs: Optional API handler class to manage API communication and data processing.
Config/KauflandConfig.cs: A serializable configuration class that stores the user's Kaufland API credentials and sync settings.
GUI Component: A WPF UserControl or Form for the configuration UI to manage Kaufland accountsettings.
README.md: A concise implementation guide to help developers set up and configure the module.
Architectural Guidelines & Development Standards
Architecture: The module should adhere to Clean Code principles and SOLID design patterns to ensure scalability, readability, and maintainability. It must not use legacy technologies and should be built using modern, robust development standards.
Unit Testing : Testing should be conducted using frameworks like xUnit or MSTest to ensure that the module functions as expected under various scenarios.
No Direct Database Access: All data interaction must pass through the middleware service layer, and the module should avoid accessing databases directly.
Summary
The Kaufland Integration Module is designed to facilitate smooth synchronization of product and order data between a Windows-based middleware system and the Kaufland marketplace. It consists of:
A C# API connector class for seamless interaction with the Kaufland Seller API.
A user-friendly WPF-based configuration interface for managing Kaufland account settings.
Standardized DTOs for reliable and consistent data exchange.
A flexible configuration system that allows for easy adjustments of sync intervals, stock thresholds, and pricing rules.
The module is built to integrate cleanly with existing middleware systems, using .NET 9 and modern software architecture principles. It is ready for implementation, and detailed documentation is included to ensure smooth setup and deployment.
