You can register a filter that will be executed after the Sleuth's TraceFilter and there you will retrieve the value of a parameter and set it as a baggage field using the BaggageField api. Remember to ensure that the remote field is set in the properties. You can read more about this in the documentation https://docs.spring.io/spring-cloud-sleuth/docs/current-SNAPSHOT/reference/html/#baggage
