<h3>Core Functionality</h3>
<p>This project is the backend for a multi-vendor e-commerce marketplace, similar to a mini-Amazon. It handles all the business logic, including user authentication, product management, order processing, and payment integration. The system supports distinct roles for buyers, sellers, and administrators, with role-based access control enforced at the API level.</p>
<h3>Key Features</h3>
<ul>
<li><strong>Role-Based Access Control:</strong> Implements custom DRF permission classes (IsBuyer, IsSeller, IsAdminUser) to ensure appropriate access for different user roles.</li>
<li><strong>Secure Payment Processing:</strong> Integrates with Razorpay for secure payment handling. Orders are created server-side, and payment signatures are cryptographically verified using HMAC-SHA256 to prevent fraud.</li>
<li><strong>Atomic Stock Management:</strong> Stock deductions are performed within database transactions to ensure data integrity. If any part of the process fails, the entire transaction is rolled back.</li>
<li><strong>Asynchronous Email Notifications:</strong> Utilizes Celery and Redis for background tasks, enabling instant API responses for order confirmations, low stock alerts, and daily sales reports.</li>
<li><strong>Inventory Alerts:</strong> Automatically notifies sellers via email when product stock falls below a configurable threshold.</li>
<li><strong>Scheduled Daily Reports:</strong> Generates and sends daily sales summaries to sellers via email using Celery Beat.</li>
</ul>
<h3>Technical Stack</h3>
<ul>
<li><strong>Framework:</strong> Django 5.1 with Django REST Framework 3.15</li>
<li><strong>Authentication:</strong> Token-based authentication</li>
<li><strong>Asynchronous Tasks:</strong> Celery 5.4 with Redis</li>
<li><strong>Database:</strong> PostgreSQL (production), SQLite (local development)</li>
<li><strong>Payment Gateway:</strong> Razorpay</li>
<li><strong>Production Server:</strong> Gunicorn</li>
<li><strong>Static Files:</strong> WhiteNoise</li>
<li><strong>Hosting:</strong> Render</li>
<li><strong>Programming Language:</strong> Python</li>
</ul>
<h3>API Overview</h3>
<p>The backend exposes REST endpoints for managing users (registration, login, profile), products (CRUD, search, filtering), and orders (cart, checkout, payment verification, status updates). Internal notification tasks are also handled.</p>
<h3>Setup and Deployment</h3>
<p>The project includes detailed instructions for local setup using Python, Redis, and Django, as well as deployment guidelines for Render, including configuration of environment variables and necessary build scripts.</p>
