If you are asking about a problem you are experiencing, please use the following template, as it will help us help you. If you have a different problem, please delete all of this text 🙂 **Kibana version** : 7.6 **Elasticsearch version** : 7.6 **APM Server version** : 7.6 **APM Agent language and version** : apm-go-agent 1.8 apmhttprouter 1.8 **Browser version** : **Original install method (e.g. download page, yum, deb, from source, etc.) and version**: debain repository **Fresh install or upgraded from other version?** no **Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc. no **Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**: I have two microservices with opentracing implmented already. I am trying to update them to support apm-server and elastic stack. Documentation says apm-agent-go supports opentracing api. After switching to apm-server, opentracing Inject and Extract (tracing out going http request) doesn't seem to work, they are recorded as separately traces. If I change to use `apmhttp.WrapClient` in client service, it works. Could it be possible use opentracing api implementation only? ---

Hi @oscar_wu, welcome to the forum! > [@](#): > > I have two microservices with opentracing implmented already. I am trying to update them to support apm-server and elastic stack. Documentation says apm-agent-go supports opentracing api. After switching to apm-server, opentracing Inject and Extract (tracing out going http request) doesn't seem to work, they are recorded as separately traces. If I change to use `apmhttp.WrapClient` in client service, it works. Could it be possible use opentracing api implementation only? Yes, the Go agent does support inject/extract with OpenTracing, but only HTTP/text; the binary carrier is not supported. Do your microservices communicate using HTTP? You can find the implementation details of these methods here: [https://github.com/elastic/apm-agent-go/blob/95e54b2e24ea813e0d059e56dfe6c740681564cb/module/apmot/tracer.go#L99-L184](https://github.com/elastic/apm-agent-go/blob/95e54b2e24ea813e0d059e56dfe6c740681564cb/module/apmot/tracer.go#L99-L184) If you can provide a small program to demonstrate the problem you're having, we might be able to provide more help. ---

@axw, Thanks for you answer. Those microservices communicate using restful http. I will give a try again. ---
