Send PDF file to a webhook with VBA

[nd0911]

I have a Make (Integromat) webhook and I want to send a PDF file via Excel VBA.
The PDF file is on my desktop path.

This is the code I have:

 Public Sub SendPDF()
 Dim URL As String
 Dim Req As Object
 Dim PdfFullPath As String
   
   
 Set Req = CreateObject("WinHttp.WinHttpRequest.5.1")
   
 On Error GoTo Er
   
   
 PdfFullPath = "C:\Users\MyUserName\Desktop\MyPDF.pdf"
   
 URL = "https://hook.make.com/xxxxxx?"
   
   
   
 Req.Open "POST", URL, False
 Req.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
 Req.Send
   
   
 MsgBox Req.ResponseText
   
 Exit Sub
   
 Er:
 End Sub

Is it possible to send a PDF to webhook with VBA ?

Thank you
