Review the “Shell” class. You can then call the curl command natively and deal with the response(s) in turn. Something like this:
Dim theShell As New Shell
theShell.Mode = 1
theShell.Timeout = -1
theShell.Execute "curl ""some command for curl"""
Do
theShell.Poll
Loop Until Not theShell.IsRunning
Dim theResult As String = theShell.ReadAll
Then continue as needed processing theResult and then executing the next command.
