HTTPS POST in VBA for Excel

Using VBA in Excel, I need to be able to make an HTTPS POST request to a server. Please note: I can already make a HTTP POST request using this code: Set web = New WinHttpRequest Const WinHttpRequestOption_EnableRedirects = 6 [login to view URL](WinHttpRequestOption_EnableRedirects) = True [login to view URL] "POST", url, True [login to view URL] "Content-Type", "application/x-www-form-urlencoded" [login to view URL] "mydata=" & data What I need is to be able to make an HTTPS request, i.e. with encryption. I tried using "[login to view URL]" to specify a certificate for HTTPS, but was unable to make it work. Please provide a working sample on how to make an HTTPS POST request in VBA. Note: you don't need to use WinHttpRequest, that's just what I tried. Please use any method which does the job, and provide a working sample plus installation instructions (if an external library such as CURL is needed, for example).
