How do you implement correlation IDs for request tracing?

Expert ASP.NET Web API

Answer

Correlation IDs enable tracking a request across microservices:

  • Generate or read a CorrelationId header in middleware.
  • Pass it to downstream services and logs.
  • Use logging scopes so all log entries share the same ID.
  • Send correlationId in the API response for client troubleshooting.
  • Critical for debugging distributed API flows.
