Http_poller plugin and parsing second level of json

[111435 (Ергали Еркалин)]

Hello, I am using Http_poller plugin for get api call.
My conf.file:

input {
  http_poller {
    urls => {
      test2 => {
        method => get
        url => "https://somethin.somethin.kz/uapi/tickets?api_token=fdfhg22fg5&fstatus=3"
        headers => {
          Accept => "application/json"
        }
      }
    }
    request_timeout => 60
    # Supports "cron", "every", "at" and "in" schedules by rufus scheduler
    schedule => { cron => "/2 * * * *"}
    # A hash of request metadata info (timing, response headers, etc.) will be sent here
    metadata_target => "http_poller_metadata"
  }
}

filter {
}...

In Elasticsearch I get this results:

But I need text in TAGS field be separated as a single fields (to be parsed too). What I have to use to separate them?
