I believe postman shows the http code you would send. Its a button on the right looks like <>.
You can also use notepad and putty to port 80 to send the same text.?
If you're building the string in Simpl or Simpl+ then \n is \r\n. If using C#, then you would need \r\n.
Your content looks like json so I'm not sure if the header Content-Type should be application/json
