VB.NET Example

Dim rest As New Chilkat.Rest
Dim success As Boolean

'  URL: https://api.stripe.com/v1/coupons/25OFF
Dim bTls As Boolean = True
Dim port As Integer = 443
Dim bAutoReconnect As Boolean = True
success = rest.Connect("api.stripe.com",port,bTls,bAutoReconnect)
If (success <> True) Then
    Debug.WriteLine("ConnectFailReason: " & rest.ConnectFailReason)
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


rest.SetAuthBasic("STRIPE_SECRET_KEY","")

rest.AddQueryParam("metadata[order_id]","6735")


Dim strResponseBody As String = rest.FullRequestFormUrlEncoded("POST","/v1/coupons/25OFF")
If (rest.LastMethodSuccess <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If
