You are trying to upload binary file content as base64 encoded text, so it’s necessary to specify the appropriate MIME header, here is the fixed snippet of your code:
request = request & sBoundary & vbCrLf
request = request & "Content-Disposition: form-data; name=file; filename=" & sFile & vbCrLf
request = request & "Content-Type: application/x-object" & vbCrLf
request = request & "Content-Transfer-Encoding: base64" & vbCrLf & vbCrLf
request = request & base64Encoded & vbCrLf
request = request & sBoundary & vbCrLf
Also you can upload a binary content of the file, here is the simplest example:
strFilePath = "C:\Users\DELL\Desktop\gt.png"
UploadFile strFilePath, strUplStatus, strUplResponse
MsgBox strUplStatus & vbCrLf & strUplResponse
Sub UploadFile(strPath, strStatus, strResponse)
Dim strFile, strExt, strContentType, strBoundary, bytData, bytPayLoad
On Error Resume Next
With CreateObject("Scripting.FileSystemObject")
If .FileExists(strPath) Then
strFile = .GetFileName(strPath)
strExt = .GetExtensionName(strPath)
Else
strStatus = "File not found"
Exit Sub
End IF
End With
