+#### `ignoreOutgoingRequestHook`
+
+The `ignoreOutgoingRequestHook` option allows you to provide a function to determine whether a specific outgoing HTTP/HTTPS request should be ignored (not traced). The function is called with the outgoing request options and should return `true` to skip tracing for that request, or `false` to allow tracing. If the function throws an error, the error will be caught and logged, and the request will be traced by default.

 ## Semantic Conventions
 
 Prior to version `0.54.0`, this instrumentation created spans targeting an experimental semantic convention [Version 1.7.0](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.7.0/semantic_conventions/README.md).
