Hi,  
I'm parsing some json data from a website using rest api with start\_timestamp of 4 hours before current time period. Is there a way within logstash to write such code to get data from last 4 hours on every runtime or is python script the way to go?

Logstash config will run every 5 minutes or so and the input url needs to have its timestamp value changes accordingly.  
`urlname => "https://targetIP/api/v1/alerts?start_timestamp=2022-09-09T00:00:00.000Z+01:00" `

logstash config:

```auto
input{
	http_poller{
		urls =>{
		    urlname => "https://targetIP/api/v1/alerts?start_timestamp=2022-09-09T00:00:00.000Z+01:00"
        }
		user => "user1"
        password => "pwd123"
		request_timeout => 60
		schedule => {every => "30s"}
		codec => "json"
		ssl_verification_mode => "none"
	}
	
}
# Working version: pls do not edit without approval
output{
	elasticsearch{
		hosts => ["https://IP:9200"]
		index => "forescout-alerts"
		ssl => true
		ssl_certificate_verification => false
		user => "uname"
    	password => pwdpwd"
	}

	stdout {codec => rubydebug}
}

```

You could use a heartbeat input to control the schedule, then use an http filter to make the request.

I'm using python script to calculate the latest timestamp and script is changing the url value. [https://targetIP/api/v1/alerts?start\_timestamp=2022-09-09T00:00:00.000Z+01:00](https://targetIP/api/v1/alerts?start_timestamp=2022-09-09T00:00:00.000Z+01:00)". Is there a way http\_poller can use the py output as url name?
