Structured API logging is implemented by initializing a full-context log at the start of each API route, then logging success or error with captured request IDs, user identifiers, endpoints, and timing for incident resolution.

Tracing API requests fails without request correlation because traditional distributed logs lack shared context. Implementing automatic context propagation links request IDs and user identifiers across services to enable end-to-end tracing.

To sanitize sensitive data in production API logs, configure automatic redaction within your logger API handlers to ensure privacy and compliance before writing logs during request processing.

Yes, you need a logger API with start, success, and error handlers to enable end-to-end request tracing. This structure allows automatic context propagation and ensures safe sanitization of sensitive data.

The best way to capture API metrics for incident response is using structured logging to automatically record duration and resource IDs. This replaces ad hoc logging and provides full context for each API call.
