The Payment Service is a crucial component of our system that handles all payment-related operations. It processes payments, manages transactions, and communicates with other services through events. Using an event-driven architecture, it ensures that all actions are asynchronous, decoupled, and scalable.

Key Components

• Payment API: Exposes endpoints for initiating payments and querying payment status.
• Payment Processor: Handles the core payment processing logic.
• Event Bus: Manages the communication between services using events.
• Payment Gateway: Interfaces with external payment providers.
• Transaction Service: Manages transaction records and states.
• Notification Service: Sends notifications related to payment status changes.
• Database: Stores transaction data and payment status.
