🎟️ Telegram Event Ticketing & Onboarding Automation

🇷🇺 Перейти к русскому описанию

A microservice-based automation system for event registration, payment processing, and rich-media onboarding. Designed with high availability in mind, featuring a dual-pipeline payment architecture to prevent lead drop-off during third-party gateway outages.

🏗 System Architecture & DevOps Approach

Built on n8n as the primary orchestrator, this project implements a fault-tolerant payment verification system:

• Pipeline A (Automated): Utilizes Telegram Native Payments API for seamless in-app transactions (sendInvoice & answerPreCheckoutQuery).
• Pipeline B (Failover/Manual): A "Human-in-the-Loop" architecture. If the primary gateway faces SLA issues, traffic is gracefully routed to a manual verification flow via interactive Admin Inline Keyboards.

📁 Repository Structure

• docker/: Infrastructure as Code (Docker Compose).
• workflows/: Production n8n JSON blueprints.
• .env.example: Standardized environment configuration.
