Functional Requirements

Build an integration framework that enables seamless interfacing between our application and various external systems through REST API for synchronous interactions and Kafka-based messaging for synch processes.

A centralized Validation Framework will be implemented to enforce consistent business rules and data integrity across all incoming requests.

Additional Non-functional requirements when building the frameworks

Ensure frameworks and interactions built are scalable and reliable

Implement robust retry, timeout, and circuit breaker patterns to handle failures or slow responses from external systems.

Ensure processing logic can safely handle duplicate or repeated messages/responses.

Handle delays or outages gracefully.

Track external API/Kafka response times, error rates, and availability to quickly detect and respond to issues.

Patterns for External API changes-monitor deprecation notices and support multiple versions if needed.

Handle if external dependency is unavailable (e.g., queue requests, return partial results, or fail gracefully).

Validate all incoming data from external sources to protect against malformed or unexpected payloads.

Ensure that all external interactions are correctly Authenticated, authorized, and handle sensitive data securely (encryption and secure transmission of confidential data).
