POST call returns "An Entity Name Must Be Provided" response

Hey All,

I am trying to create a user and organization via TW API calls, (not through the Composer).

and everytime I do it, I get "An Entity Name Must Be Provided" response.

Interesting thing is, call works on POSTman but it doesnt work on my node script. I made sure I put headers and everything same with the postman, but still I get "An Entity Name Must Be Provided"

Here is my post call on Node script

app.get('/hey/:name', function (req, res) {

  var payload = {

  method:'POST',
  url: 'https://XXXX.net/Thingworx/Resources/EntityServices/Services/CreateUser?appKey=XXXXXXXXXXXXXXX,
  headers: {

       'ACCEPT':'application/json',
       'Content-Type':'application/json',
       'Access-Control-Allow-Origin': '*',
  },
  data: {

       'name':req.params.name,
       'password':req.params.name,
       'description':req.params.name
  }

  }

  request(payload, function (err,response,body) {

  //var data = JSON.parse(body);
  //console.log(data);
  res.send('Hello '+body)

  })

any idea how I can get this working?

Thanks,

Mustafa
