## Instant Cash Micro-service

1. **Overview**

    - This micro-service is designed to integrate with the Instant Cash Exchange House API, providing functionalities

      for managing transactions, including fetching outstanding transactions, checking transaction status, and

      confirming transaction statuses.

    - The service is built using Java and Spring Boot, and it utilizes the Spring Scheduler for periodic task execution.

    - It includes a properties file for configuration, a controller for handling API requests, and a service for

      processing the business logic.

    - The service is designed to be modular and easily extendable, allowing for future enhancements and additional

      features as needed.

    - The service is also designed to be robust and handle various error scenarios, ensuring that the system remains

      stable and reliable even in the face of unexpected issues.

    - The service includes comprehensive logging and monitoring capabilities, allowing for easy tracking of system

      performance and identifying potential issues.

    - The service is designed to be secure, with appropriate authentication and authorization mechanisms in place to

      protect sensitive data and ensure that only authorized users can access the system.

    - The service is designed to be scalable, allowing for easy expansion and growth as the needs of the business change

      over time.

    - Microservices are built using Spring Boot, which provides a lightweight framework for creating standalone

      applications.

    - Each microservice is designed to be independent and self-contained, with its own database and business logic.

    - Microservices communicate with each other using RESTful APIs or messaging queues (e.g., Kafka).

    - The microservices architecture allows for easy scaling and deployment of individual services, enabling faster

      development and deployment cycles.
