Hello,
I'm on Logstash v7.17, using 'http output' plugin to send logs to third party API.
> **[Http output plugin | Logstash Reference \[7.17\] | Elastic](https://www.elastic.co/guide/en/logstash/7.17/plugins-outputs-http.html#plugins-outputs-http-mapping)**
Per third party API spec and hard requirement, "zip" POST property must be a number, otherwise API rejects it.
When I use "mapping" setting (example below), every property, including "zip", which is hardcoded as an int, still gets sent as a string.
Is there any way to send it as a number (int or float)?
```auto
output {
http {
url => "url.com"
http_method => "post"
format => "json_batch"
codec => "json"
mapping => {
"name" => "Test User"
"address" => "1234 Some Street"
"zip" => 50001
}
}
}
```

I don't think so. There is an [open issue](https://github.com/logstash-plugins/logstash-output-http/issues/136) about this and [another](https://github.com/logstash-plugins/logstash-output-http/issues/134) that I think says the same for booleans.
I suspect the problem will be something like [this](https://github.com/guyboertje/jrjackson/blob/8379708e06579d9b76cd3567aed0493e6a60b89b/lib/jrjackson/jrjackson.rb#L67). logstash uses JrJackson but I haven't followed through the dependencies to be certain that that is the exact code in play.
You may be able to work around it using something like
```
codec => plain
content_type => "application/json"
message => '{ "name": "%{name}", "address": "%{address}", "zip": %{zip} }'
```

Thank you for the suggestion and sending me in the right direction. Only needed to set `format` to `message` and now able to dictate the type using `message` option instead of `mapping` (as shown above). 🙏

```auto
If message, then the body will be the result of formatting the event according to message
```
