title: How to read the output from a http filter plugin in logstash and store it in elasticsearch index
body: <p>I have a use case where I have to make an external HTTP call to an API endpoint in the <strong>logstash</strong> by passing the input coming from kafka as the body and read the output from the API call and store it in elasticsearch index. Can we achieve this through HTTP filter plugin? If so, my main question is how do we read the output from the API call and index it into elasticsearch.</p>
  <p>I also see something called as http poller plugin, is this something that will be of use to me? Help would be appreciated. Thank you.</p>
