Sending data to cloud Logstash pipeline

Elastic Stack Logstash
1

I have setup a Logstash pipeline in Elastic Cloud but I can't find any information on how to send data to it e.g. URL, port etc. Please can someone point me at any docs or let me know?

What does your input section look like?

It's just a simple TCP input at the moment

 input {

  tcp {
    port => "28777"
    codec => json
  }
}

This is part of what I need to find out about, what inputs can I use, and how to reference them externally from our applications.
