I want to let the users download a PDF that is received back from a API after a Json request. When a user opens ShowPDF.asp the request happens and there opens a new window where the PDF is downloaded.
The problem is that the downloaded PDF is not valid; it says that the file can't be opened. The size of the file is around 500kb, so there is something in it. When I make the same request in Postman I see the content from the PDF file in the result screen and when I save it it's also around 500kb.
What is received back from the request is the actual content of the PDF file:
%PDF-1.4
3 0 obj
<</Type /Page
/Parent 1 0 R
The code:
PDF.asp
Response.AddHeader "Content-Disposition","attachment; filename=name.pdf
Response.ContentType = "application/pdf"
PDFcontent = GetPDF(strToken)
response.write PDFcontent
GetPDF(sToken)
public function GetPDF(sToken)
Set xmlhttp = CreateObject("Msxml2.ServerXMLHTTP.6.0")
xmlhttp.open "GET", "www.fakeUrl.com/rest/download", false
xmlhttp.setRequestHeader "Authorization", "Bearer "& sToken
xmlhttp.setRequestHeader "Content-Type", "application/json; charset=UTF-8"
xmlhttp.send ""
GetPDF = xmlhttp.responseText
end function
ShowPDF.asp
window.open('PDF.asp');
What am I missing here?

The problem is you are treating the download of a binary file as if it was text. But luckily the fix isn't too difficult.
Adjust the
GetPDF = xmlhttp.responseText
to
GetPDF = xmlhttp.responseBody
Then change
response.write PDFcontent
to
Response.BinaryWrite PDFcontent
