Project description:
"Project Overview

We are looking to build a robust, modular, and scalable URL shortener service for our application. This is not a standalone project; the service must be designed as a self-contained module that can be seamlessly integrated into our existing infrastructure.

The core purpose of this service is to provide powerful link tracking, detailed analytics, and compliant data handling for all short URLs generated within our platform. You will be responsible for building the backend logic, the database schema, and a simple frontend dashboard for analytics.

Project Scope & Key Features

You will be tasked with implementing the following features:

1. Core Functionality & Tracking:
Per-Recipient Click Tracking: The system must store `recipient_id`, `campaign_id`, `click_time`, and the associated `url_hash` for each click to enable personalized analytics.
Redirection & Error Logging: Implement the core redirection logic. Crucially, if a link fails to redirect (e.g., target URL is 404, blocked by a bot), this error must be logged to help users debug their campaigns.
Double-Click Prevention: Introduce a 30-second cooldown window for identical clicks from the same source to prevent spam and ensure cleaner, more realistic analytics.

2. Analytics & Privacy (Compliance-focused):
Device & Location Metadata: Capture essential metadata from the user agent, such as OS, browser, and IP address.
IP & Geo-Privacy Compliance: Ensure user privacy by anonymizing IP addresses (e.g., masking the last octet `123.45.67.*`) and storing only city/region-level location data, not exact coordinates. This is a mandatory requirement.
Consent Logging: Each click event must include a `clicked_at` timestamp and a `source` field (e.g., 'sms', 'email', 'app') .
Data Auto-Expiration (TTL): Automatically purge click metadata after 90 days.

3. Technical & Security Requirements:
HTTPS-Only:All short links and internal redirects must be served exclusively over HTTPS (SSL).
Modular API Design: The primary deliverable is a well-documented REST API that our main application can call to create, manage, and retrieve analytics for short URLs.

4. Features Must Have
Branded Short URLs (Custom Domain): The service must support the use of a custom domain (e.g., [login to view URL]) for generating all short links.

Dynamic URL Path Prefix: Implement the ability to add a dynamic prefixto the short URL path for compliance.(https://[YourBrandDomain]/{SenderID}/{UniqueID})

Built-in UTM Parameter Builder: A user interface to easily add and manage UTM tags (utm_source, utm_medium, utm_campaign) for destination URLs to track performance across channels like WhatsApp, SMS, and email.

Real-time Click Event Webhooks: The system must be able to trigger a webhook to an external endpoint whenever a link is clicked, sending the click data in real-time.

Analytics Data Export: A feature to export raw click data andanalytics in CSV/xls/xlsx format.
