Trace requests across services
Adding correlation IDs means generating or propagating a request ID at the edge, passing it through headers, logging it everywhere, and surfacing it in errors to connect traces, logs, and metrics across services.

Generate/Propagate
Set an ID at ingress; keep it in headers across calls.
Log and Trace
Include the ID in logs, traces, and metrics tags.
Expose Safely
Return the ID in errors/support contexts; avoid leaking sensitive info.
