You can send fax with PDF, all you need is to create a multipart/mixed request and add each PDF as an attachment. You can either send the raw bytes or base 64 encode the file.

There are many way to do this with C# is to use (alpha) SDK which is available on Nuget and GitHub:

Get the package from Nuget and follow the fax instructions under "Send Fax" on the GitHub link.
