WinINet functions do not support SFTP protocol (FTP protocol is completely different).

There's no native support for SFTP in VBA nor in Windows API. You have to use a 3rd party library or software.

See these questions for some examples:

Using WinSCP scripting: Using VBA to run WinSCP script
Using WinSCP .NET assembly: Getting "user defined type not defined" when trying to use WinSCP .NET assembly in VBA to upload file to SFTP

(I'm the author of WinSCP)
