We would like to use filebeat to accept data from Apache Nifi in the form of a POST request, run it through some processors and send it to Elasticsearch. The [documentation on the http\_endpoint](https://www.elastic.co/guide/en/beats/filebeat/7.13/filebeat-input-http_endpoint.html#_content_type) seems to suggest that the http\_endpoint usually expects data to be JSON-formatted - however this can be overruled by setting the content\_type setting to something else:
_By default the input expects the incoming POST to include a Content-Type of application/json to try to enforce the incoming data to be valid JSON. In certain scenarios when the source of the request is not able to do that, it can be overwritten with another value or set to null._
This is required for us because we receive large volumes of CSV data. However, it seems like the http\_endpoint expects data to always be JSON-formatted, no matter what the content\_type is configured to be.
Example filebeat.yml:
```auto
filebeat.inputs:
- type: http_endpoint
enabled: true
listen_address: 0.0.0.0
listen_port: 8889
content_type: ""
output.console:
```
Example curl command once you start filebeat:
```auto
$ curl -d 'this,is,a,test' localhost:8889/ -XPOST
{"message": "Only JSON objects are accepted"}
```
Am I simply misunderstanding the documentation and this is intended functionality, or could this be a bug?

Hi!
`content_type` is meant only for content checks, you can leave it blank if the sender does not add the appropriate header but the content still needs to be a valid json.

Thanks for the clarification. IMO it would be helpful if the documentation on this input explicitly explained that only JSON is accepted - as it is written, it can confuse noobs such as myself 🙂
