Okta - Primary Authentication with Public Application using VB.Net - okta

Question

Using the API documentation, we are trying to use this for authenticating:
Primary Authentication with Public Application:
http://developer.okta.com/docs/api/resources/authn.html#primary-authentication-with-public-application:
Authenticates a user with username/password credentials via a public application
Request Example
curl -v -X POST \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-d '{
"username": "dade.murphy#example.com",
"password": "correcthorsebatterystaple",
"relayState": "/myapp/some/deep/link/i/want/to/return/to",
"options": {
"multiOptionalFactorEnroll": false,
"warnBeforePasswordExpired": false
}
}'
Trying this in VB.Net, we get:
Dim request As WebRequest = WebRequest.Create("https://dev-XXX.oktapreview.com/api/v1/authn")
request.Credentials = New NetworkCredential(.UserName, .Password)
request.ContentType = "application/json"
request.Method = "POST"
Dim response As WebResponse = request.GetResponse()
When we get to the response, it gives an error of "The remote server returned an error: (400) Bad Request." and no more helpful info.
Obviously what we want to do is to do a WebRequest with the properly formatted parameters and return a WebResponse that we can interrogate for the Success Response:
{
"expiresAt": "2015-11-03T10:15:57.000Z",
"status": "SUCCESS",
"relayState": "/myapp/some/deep/link/i/want/to/return/to",
"sessionToken": "00Fpzf4en68pCXTsMjcX8JPMctzN2Wiw4LDOBL_9pe",
"_embedded": {
"user": {
"id": "00ub0oNGTSWTBKOLGLNR",
"passwordChanged": "2015-09-08T20:14:45.000Z",
"profile": {
"login": "dade.murphy#example.com",
"firstName": "Dade",
"lastName": "Murphy",
"locale": "en_US",
"timeZone": "America/Los_Angeles"
}
}
}
}
Thanks in advance!

You are setting credentials on the request instead of sending the JSON payload.
