Hello All, I am actually taking beats as an input and I need to pre-process the data in the filter section of logstash before sending to elastic search.The data should be pre-processed by calling a rest service in the filter [section.Is](http://section.Is) there any filter plugin to do so..? The response from the web service is then to be added to the Elasticsearch. Thanks in advance ! Regards, Preehana ---

The [logstash-filter-rest](https://github.com/lucashenning/logstash-filter-rest) plugin should help. You can get more context about this plugin in the [original issue](https://github.com/elastic/logstash/issues/3489). ---
