Hello,  
I am using HTTP input plugin in logstash config. I have been always sending data to logstash over HTTP POST method by using logstash API like this;

`curl -XPOST http://<logstashIP>:9605 -d '{"my": "data"}'`

also my config like this;

```
input {
  http {
    port => 9605
    codec => "json"
  }
}
filter {
  json {
     source => "messages"
  }
}
output {
  stdout { codec => rubydebug }
}

```

But is there a way to send data to logstash with basic authentication like this;  
`curl -XPOST -u 'user:password' http://<logstashIP>:9605 -d '{"my": "data"}'`

The purpose is to send data to logstash securely.

Many thanks

Yes. The [documentation](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-http.html#_security) covers that.

Thanks @Badger now i can send data with basic auth. But logstash returns error when i use keystore for password.  
I have added the LS\_PWD for password;

```auto

es_pwd
es_usr
ls_pwd

```

Then i passed in input section;

```
input {
  http {
    user => "alican"
    password => "${LS_PWD}"
    port => 9605
    type => "north"
    codec => "json"
  }
}

```

ERROR;

```auto

I think the input section does not support **secret store** but its works with environment variable `export LS_PWD="mypassword"`
