Hello !
I am currently looking to considerably improve our data-enhancement and ingesting pipeline by trying to give more responsabilities to ELK.
Currently before inserting time of a document, I call few APIs (gRPC but can be migrating to REST pretty easily) to enhance it, add some fields and once the response received I transform the data and insert it.
I know that LogStash is pretty efficient to tansform the data, I would like to know if there is any mechanism inside LogStash to call some APIs to add some fields to a given document at Ingest Time inside LogStash ? If yes, is that a good pattern ?
Best !

Yes you can use [http filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-http.html) for that.
