Hi all

We are currently using filebeat and grok filter to extract a document number from a text file. now we would like to receive additional information about the document that is not in the same file.

is there a way after we received the document number to request additional information from a web service?

We already found http poller as input plugin but is there a way to combine this?

many thanks for your help in advance!

Use an [http](https://www.elastic.co/guide/en/logstash/current/plugins-filters-http.html) filter?

Isn't the http filter only for REST APIs?

"The HTTP filter provides integration with external web services/REST APIs."

You said you wanted to get additional information from a web service. I don't think the http filter actually requires that the service satisfy all of the REST constraints.

hi badger and sorry for my late reply.

i tried the http filter but unfortunately without success. http filter always sends content-type: text/plain, we need text/xml 🙄

see also [https://github.com/logstash-plugins/logstash-filter-http/issues/15](https://github.com/logstash-plugins/logstash-filter-http/issues/15)
