Does the HTTP Event Collector API support events with arbitrary metadata? (2019 edition)

[olivercole]

3 years ago, someone asked my exact question:

"Does the HTTP Event Collector API support events with arbitrary metadata?" (can't add a link, no karma)

In short, POSTing {"event": "hello world", "foo": "bar"} results in {"text":"No data","code":5}.

Has the answer changed significantly in the intervening time? If so, in which version, and is there any documentation?

I'm using logstash 5.6 as a client.

What is it you are trying to solve? Because it depends what you mean by metadata and if you can control the HEC payload.
