400/404 error on POST request

Hey, I'm trying to do my very first POST API call and currently getting stuck. I know there are other solutions for what I'm trying to do, but I'm also trying to learn something rather than straight...

    It also took me a bit of back and forth to get it working. Reasons are due to Khoros Classic using an older version of jQuery and some specific JSON requirements:

    1. Since Classic's jQuery version is older you need to use type: "POST" instead of method: "POST"
    2. The contentType "application/json" needs to be specified
    3. data parameter needs to be stringified (you already were on the right tracke with your v2)

    Here's the resulting evolution of your v1 code that works on my end:

    <#assign boardID = coreNode.id />

<button id="subscribe">AJAX test</button>

<@liaAddScript>
  (function($){
    $(document).ready(function(){
      $("#subscribe").on( "click", function() {
        $.ajax({
	  url: "/api/2.0/subscriptions",
	  contentType: "application/json",
	  dataType: 'json',
	  data: JSON.stringify({
	      type:"subscription",
	      target:{
	        type:"board",
                id:"blueprints"
	    }
	  }),
	  type: 'POST'
	}).done(function(response) {
	  console.log('Success');
	}).fail(function() {
	  console.log('Fail');
	})
      });
    });
  })(LITHIUM.jQuery);
</@liaAddScript>

    Bonus tip:
    Looking at the details in your browser's network tab will reveal that quite often the HTTP error code is hiding a different more detailed "developer message" debug info in the return data. E.g. here's a HTTP 500 error that is hiding a message about non-stringified content:

I've made a few revisions - mostly stabs in the dark, but got rid of the 404 response. Now I'm getting 400 (Bad Request) in response from the API. Would really appreciate if anybody who's been through similar growing pains is able to share some wisdom. I don't understand why it's unhappy with the request.

<#assign boardID = coreNode.id />

<button id="subscribe">Subscribe</button>

<@liaAddScript>
  (function($){
    $(document).ready(function(){
      $("#subscribe").on( "click", function() {
        $.ajax({
          type: 'post',
          url: "/api/2.0/subscriptions",
          dataType: 'json',
          data: JSON.stringify({
            "type":"subscription",
          "target":{
            "type":"board",
            "id":"${boardID}"
            }
          })
        }).done(function(response) {
          console.log('Success');
        }).fail(function(response) {
          console.log('Fail');
        })
      });
    });
	})(LITHIUM.jQuery);
</@liaAddScript>

    Check the network request tab when this is sent; I suspect the payload is incorrect. 

    The docs say the JSON body should look like

    {
  "data": {
    "type": "subscription",
    "target": {
      "type": "board",
      "id": "some-board"
    }
  }
}

    but I suspect your payload will look like

    {
  "type": "subscription",
  "target": {
    "type": "board",
    "id": "some-board"
  }
}

    and you're being mislead that the parameter for passing data is "data", but you also need to include "data" as part of the JSON itself.
