Contact Deletion using SSJS [Delete all contacts in a DE using API]

<script runat="server">
 Platform.Load("core ","1.1.5 ");
  
  try{
  /* var eid = Platform.Function.AuthenticatedEnterpriseID(); use this if running from parent BU else hardcode as below*/
  var eid = '51000xxxx';

  payload += ' "scope ": "list_and_subscribers_write ",';
  payload += ' "account_id ": " ' + eid + ' " ';
  payload += '}';
  
  var result = HTTP.Post(authUrl, contentType, payload);
  var response = result["Response "][0];
  var accessToken = Platform.Function.ParseJSON(response).access_token;

JSON parsing using SSJS

Example: JSON
[
  {
    "Prod_ID ": 1,
    "Prod_Name ": "Nike",
    "Prod_Desc ": "Shoe"
  },
  {
    "Prod_ID ": 5,
    "Prod_Name ": "Puma",
    "Prod_Desc ": "Slipper"
  },
  {
    "Prod_ID ": 10,
    "Prod_Name ": "Adidas",
    "Prod_Desc ": "Jacket"
  }
]

<script runat="server">
    Platform.Load("Core","1.1.1");
    var json = Platform.Request.GetPostData();
    var products = Platform.Function.ParseJSON(json);
    
    if (products.length > 0) {
        for (var i = 0; i < products.length; i++ ) {
            var item = products[i];
            Platform.Variable.SetValue("@Prod_ID",item['Prod_ID']);
            Platform.Variable.SetValue("@Prod_Name",item['Prod_Name']);
            Platform.Variable.SetValue("@Prod_Desc",item['Prod_Desc']);
    </script>
            <br>Prod_ID = %%=v(@Prod_ID)=%%  || Prod_Name = %%=v(@Prod_Name)=%% || Prod_Desc = %%=v(@Prod_Desc)=%%
    <script runat="server">
        }
    } 
    else 
    {
        Write("no products found");
    }
</script>

Run automation in Child BU from Parent BU [via Script activity]

<script runat="server">
Platform.Load('core', '1');
   MyFunc = {
    Init: function(ObjectID,MID) {
    var obj = {};
    
    obj.Perform = function() {
    try {
        var program = Platform.Function.CreateObject("Program ");
        var clientID = Platform.Function.CreateObject("ClientID ");
        Platform.Function.SetObjectProperty(clientID, "ID ", MID);
        Platform.Function.SetObjectProperty(clientID, "IDSpecified ", "true ");
        Platform.Function.SetObjectProperty(program, "Client ", clientID);
        Platform.Function.SetObjectProperty(program, "ObjectID ", ObjectID);
        Platform.Function.InvokePerform(program, "Start ", status);
        return status[0];
        }  
      
    catch (err) { return err.message; }
    };
    return obj;
    }
   };

   var myClientID = [MID]; // Your Business UNIT MID
   var myAutomation = "[automationExternalKey] "; // NOT the name! use ExternalKey
   var childAutomation = MyFunc.Init(myAutomation,myClientID);
   childAutomation.Perform();
</script>

SSJS to make an HTTP POST request

<script runat=server>
Platform.Load("core", "1.1.1");

/* Parameters sent in POST */
var First_Name = Request.GetQueryStringParameter("First_Name");
var Last_Name = Request.GetQueryStringParameter("Last_Name");
var Email_Address = Request.GetQueryStringParameter("Email_Address");

/* Comment below once you complete debugging */
Write('First_Name = '+  First_Name);
Write('Last_Name = '+  Last_Name);
Write('Email_Address = '+  Email_Address);

var url = 'https://enhymz81cmxk5.x.pipedream.net';

/* Make sure NO spaces in below JSON */
var payload = '{"First_Name":"'+First_Name+'","Last_Name":"'+Last_Name+'","Email_Address":"'+Email_Address+'"}';

var req = new Script.Util.HttpRequest(url);
req.emptyContentHandling = 0;
req.retries = 2;
req.continueOnError = true;
req.contentType = "application/json"
req.setHeader("API-TOKEN", "xxxxx");
req.method = "POST"; 
req.postData = payload;

var resp = req.send();
</script>

Get n SET variables in JS vs SSJS variables

  <html>
    <head>
    <title>SFMC Ninja</title>
            <script runat="client">
                var JS_variable = "Welcome to ";    //Setting Javascript Variable
                console.log(JS_variable);           //Output to console from Javascript
            </script>
    </head>
    <body>
            <h1 id='header'></h1>                   <!-- Placeholder for HTML output -->
    
            <script runat='server' language='javascript'>
            Platform.Load('Core','1.1'); 
            var SSJS_variable = "SFMC ";            //Setting SSJS Variable
            </script>
     
            %%[SET @AMPscript_variable = "Ninja"]%%  <!-- Setting AMPscript Variable -->
    
            <script runat=server>
                var message = SSJS_variable + Variable.GetValue("@AMPscript_variable"); //Concat SSJS + AMPscript variables
                Write('<script>console.log("' + message + '")</script>');   //Output to console from SSJS
            </script>
    
    <script runat="client">
    document.getElementById("header").innerHTML = JS_variable + "SFMC " + "%%=v(@AMPscript_variable)=%%"; //HTML output using JS + AMPscript 
    </script>
    
    </body>
    </html>
