Overview & Background

SeatSnap is a production-ready event ticketing and management platform featuring a complete user booking flow, secure payment integration with PhonePe, QR-code based ticket validation, and a comprehensive admin dashboard. Built with Next.js App Router and Firebase, it handles events, movies, and plays with real-time data management and email confirmations.

The Problem

Event organizers need an all-in-one platform for ticketing, payments, and access control.

The Solution

Full-stack platform with payment gateway, QR tickets, and role-based admin panel.

The Outcome

Secure booking system with automated confirmations and seamless ticket validation.

The Challenge & Bottlenecks

Traditional event ticketing systems face several architectural and operational challenges:

Complex payment gateway integration with secure webhook handling and signature verification.

Secure ticket generation and validation to prevent counterfeiting and fraud.

Managing multiple event categories (events, movies, plays) in a unified database schema.

Enforcing role-based access control (RBAC) securely on serverless endpoints.

Engineering Focus:This project delivers a complete solution covering the entire ticketing lifecycle from booking to entry validation.

Project Goals & Requirements

Clear functional criteria and architectural targets established for this build.

Core Deliverables

Integrate PhonePe payment gateway with secure webhook processing.

Build admin CRUD interfaces for events, movies, and plays.

Implement Firebase-based authentication with custom role claims.

Generate unique downloadable QR-code tickets for verified bookings.

Technical Constraints

Secure payment processing with SHA-256 payload verification

Server-side role validation using Firebase Admin SDK

Responsive design optimized for mobile and desktop booking flows

Sub-second query performance on event catalog listings

Key Features & Technical Breakdown

Core modules engineered to deliver speed, reliability, and security.

PhonePe Payment Gateway Integration

Complete payment flow with API initiation, redirect handling, and webhook verification. Supports secure transaction processing with SHA-256 signatures and handles payment success/failure callbacks gracefully.

Role-Based Admin Dashboard

Protected admin routes using Firebase custom claims. Organizers can create, edit, and manage events, movies, and plays. Includes booking management and real-time message viewing interfaces.

Multi-Category Event Management

Supports three event categories (events, movies, plays) with dedicated detail pages, custom booking flows, and admin tables with dynamic pricing structures.

System Architecture

The application uses Next.js App Router for file-based routing with server and client components. Firebase handles authentication, database, and admin operations, while serverless API routes manage payment processing and webhooks.

Dynamic code splitting to minimize initial bundle size

Key Architectural Takeaways

Insights and lessons gained from building and testing this system in production environments.

Payment gateway integration requires strict webhook verification and idempotency handling to prevent double-charging.

Firebase custom claims are powerful for role-based access but need proper token refresh flows on auth state change.

QR code generation and scanning can be efficiently handled client-side with proper server validation.

TypeScript strict mode catches critical edge cases in payment and booking state machines.
