my current apm configuration is as follows:

config.apm = {  
serviceName: 'MyService',  
secretToken: '',  
serverUrl: 'localhost:5601',  
captureBody: 'all',  
instrument: 'true',  
errorOnAbortedRequests: 'true'  
};

var apm = require('elastic-apm-node').start({  
serviceName: config.apm.serviceName,  
secretToken: config.apm.secretToken,  
serverUrl: config.apm.serverUrl,  
captureBody: config.apm.captureBody,  
});

the http request body is captured correctly. I would like to know if there is an existing way to capture the response too.

Not automatically, but if you have the body in a variable, you can attach it to the transaction manually by calling [`apm.setCustomContext()`](https://www.elastic.co/guide/en/apm/agent/nodejs/current/agent-api.html#apm-set-custom-context), eg:

```
apm.setCustomContext({
  responseBody: body
})

```

Just remember to call this function before the request have ended.
