How to Enable HTTP Wire Logging for HTTP Connector or Other Connectors Using HTTP Service for Mule Applications

Publish Date: Mar 5, 2026

Task

In Mule applications, enable DEBUG logging for inbound/outbound HTTP traffic handled by connectors utilizing the HTTP Service:

Important:

Enable DEBUG logging only for troubleshooting. Avoid leaving it enabled indefinitely or unsupervised, as it can negatively impact API performance.
The debug logs will display HTTP headers and payload in plain text.

Steps

HTTP Listener: Assuming your HTTP Listener configuration is named “CUSTOM_NAME”, set DEBUG logging level for the following package:
- org.mule.service.http.impl.service.HttpMessageLogger.CUSTOM_NAME

HTTP Request: Assuming your HTTP Request configuration is named “CUSTOM_NAME2”, set DEBUG logging level for the following package:
- org.mule.service.http.impl.service.HttpMessageLogger.http.requester.CUSTOM_NAME2

The custom names used in these examples are the “name” attributes of the “http:listener-config” or “http:request-config” XML items.

If you need to troubleshoot more details about the HTTP service (not just the payload/headers), please refer to How to enable all HTTP Service debug modes? - Enhanced HTTP Wire Logging for Mule 4 APIs.
