Setting up a Post Request

In Java

A tutorial on sending a post request via Java to a service can be found here. The first example using the HttpURLConnection is recommended as it does not rely on the Apache framework

In JavaScript

There is a solid tutorial here on use of a generic AJAX method for sending a get/post request using vanilla JS.

Postman

In Chrome browser, you can use the Postman chrome extension
As desktop application: download Postman here

Make sure request is a POST request
Set the URL to be https://data.oceannetworks.ca/sos
