Sending form dat in req.body and testing via POSTMAN - having issues

[Lucky Jindal]

Since I use node.js, I thought it could be node and configuration issue so I am posting my problem here.

1. Front end submits post request

this.http.post('utl', { formData: formData}).subscribe())

So my form data is wrapped in formData.

2. At backend, I catch the POST request via router 

myRouter.post("utl",(req,res)){

   var formData = req.body.formData; // I see formData fine here

}

3. But when I want to test same with POSTMAN or REST Client, I am completely unable to send formData.

I tried -

Postman -> raw body -> "x-www-form-urlencoded "-> different things /ways to set formData and formData contains JSON object. 

Tried application/json too. 

Please help in finding right way to test this, so we do not have to use front end.
