VAT Validation Microservice

The VAT Validation Microservice is a web application consisting of two parts: a backend service and a frontend validation UI. The microservice allows users to validate VAT-IDs (Value Added Tax Identification Numbers) against the official EU VAT Information Exchange System (VIES) database.

Features

• Validate VAT-IDs against the VIES database
• Display validation results including company information
• User-friendly web interface for easy interaction

Architecture

The application follows a client-server architecture, with the following components:

• Backend Service: A RESTful API service built using Java and Spring Boot. It interacts with the VIES database to perform VAT-ID validations and provides endpoints for the frontend UI.
• Frontend Validation UI: A React-based user interface that allows users to enter VAT-IDs, initiate validation requests, and display the validation results.

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Node.js and npm (Node Package Manager) installed on your system
