Format of JSON payload in Azure Logic App HTTP Request trigger

Question

I have been trying to create a very simple Logic App in Azure but I keep failing because it does not seem to be accepting my JSON.

Using my payload

{
  "userPrincipalName": "notmy@ddress.com",
  "computerName": "MyComputername"
}

I created the trigger

I then use the values of my payload in my response:

Save it and then I POST using Hurl.it to the HTTP POST URL in the request.

So why the heck is the value not used? I'm not able to use any of the values I'm sending.
