The API Gateway must audit exceptions and errors that occur during the processing.

The API gateway must audit exceptions and errors that occur during processing to ensure robust security, reliable performance, and effective troubleshooting. As the central entry point for all incoming API requests, the gateway is responsible for managing traffic and routing requests to the appropriate backend services. Auditing errors and exceptions allows the gateway to capture critical issues such as request processing failures, system outages, or unexpected behaviors, providing insights into the health and stability of the entire API ecosystem. By logging these events, the gateway can help identify recurring issues, misconfigurations, or security vulnerabilities that might otherwise go unnoticed. This is essential for detecting potential attacks, such as denial-of-service (DoS) attempts or malicious behavior that exploits system flaws.
