Elastic.co account and billing summary dashboard

I got your point and referring Billing API documentation,

Now I am testing billing API for "Get costs to overview for the organization"

Config file and Output attached. Getting error of Invalid URL or root unauthenticated.
Although I search for HTTP poller authentication, got this link, but didn't get much idea how to process it in URL.

https://discuss.elastic.co/t/http-poller-authentication-encode-token/143532

This config setting is just for testing purpose-

input{
http_poller {
        type => "billing"
        urls => {
          url => "https://api.elastic-cloud.com/api/v1/billing/costs/<orgid>-HAuthorization:ApiKey<my api key>"
        }
        request_timeout => 60
        schedule => { every => "5s"}
        codec => "json"
    }

}
output {
    stdout {
        codec => rubydebug
    }
    #elasticsearch {
        #host ip to be changed to new test system
        # hosts => ["<hostaname>"]
       #index => "<Billing>"
   # user => "<username>"
      # password => "<password>"
   #}

}

Output

-bash-4.2$ sudo bin/logstash -f /etc/logstash/conf.d/billing1.conf
