' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http

http.BasicAuth = True
http.Login = "API_USERNAME"
http.Password = "API_PASSWORD"

Dim json As New Chilkat.JsonObject
Dim success As Boolean = json.UpdateString("merchid","MERCHANT_ID")

Dim url As String = "https://<site>.cardconnect.com:<port>/cardconnect/rest/"
Dim responseStr As String = http.PutText(url,json.Emit(),"utf-8","application/json",False,False)

If (http.LastMethodSuccess = False) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' If we get a 200 response status and an HTML response saying "CardConnect REST Servlet", then our credentials are correct.
Debug.WriteLine("response status code = " & http.LastStatus)

Debug.WriteLine("response string:")
Debug.WriteLine(responseStr)

' Sample output:

' response status code = 200
' response string:
' <html lang="en"><body><h1>CardConnect REST Servlet</h1></body></html
