HI , I want to know how to upload pdf file into NetSuite API.
I tried to upload PDF file but the error is coming ' Please enter value(s) for: Folder'
what value will come in the FIle url.
Please help me out in this.
Thank you

Try
$uploadFile->folder = new RecordRef();
$uploadFile->folder->internalId = 19;

instead of
$folderRef = new RecordRef();
$folderRef->internalId = 19;

$uploadFile->folder = $folderRef;
