Solution 1:

I think your code is bulky and buffers up the entire file.pdf into memory (body) for every request before writing the result back to clients, it could start eating a lot of memory if there were many requests at the same time, that's why you should use streams:

server.get('/apisd', function(req, res, next) {

    // Force browser to download file
    res.set('Content-Type', 'application/pdf');
    res.set('Content-Disposition', 'attachment; filename=file.pdf');

    // send file
    request.post({
        url: 'http://<api_url>',
        oauth: oauth,
        preambleCRLF: true,
        postambleCRLF: true
    }).pipe(res);

});

By using streams the program will read file.pdf one chunk at a time, store it into memory and send it back to the client.
