Print PDF’s on Azure Using an API and RazorLight (Update 1)

The API mentioned in my first tutorial got taken down and so I had to do some updates. First, choose another 3rd party API. I currently am trying out HTML 2 PDF Rocket and modified my code a bit:

    public async Task<FileStreamResult> PrintAsync(int id)
        InvoiceVM invoiceVM = new InvoiceVM();
        invoiceVM = invoiceRepository.Get(id);
        var engine = new RazorLightEngineBuilder()
          .UseFilesystemProject(_hostingEnvironment.WebRootPath + "\\pdf\\")
        var view = await engine.CompileRenderAsync("PDF.cshtml", invoiceVM);
        string apiKey = "xxxxxxxxxxxxxxxxxxxx";
        using (var client = new WebClient())
            // Build the conversion options
            NameValueCollection options = new NameValueCollection();
            options.Add("apikey", apiKey);
            options.Add("value", view);
            options.Add("MarginLeft", "10");
            options.Add("MarginRight", "10");
            options.Add("MarginTop", "10");
            options.Add("MarginBottom", "10");
            options.Add("PageSize", "Letter");
            MemoryStream ms = new MemoryStream(client.UploadValues("", options));
            return new FileStreamResult(ms, "application/pdf");

This is based directly off the HTML 2 Rocket documentation. For the rest of the code see the first tutorial.
