Answer 1

In our app(angular) we had to create an object url for that with a code like:

WebApi:

result = Request.CreateResponse(HttpStatusCode.OK);
result.Content = new ByteArrayContent(data);
result.Content.Headers.Add("Content-Type", "application/pdf");
result.Content.Headers.ContentDisposition =
                        new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
                        {
                            FileName = "FileNameHere"
                        };

return result;

javascript:

// HttpCall in here
// On SuccessResponse
    var file = new Blob([data], {
                    type: 'application/pdf'
                    });
    var fileURL = URL.createObjectURL(file);
// create an anchor and click on it.
    var ancorTag = document.createElement('a');
    ancorTag.href = fileURL;ancorTag.target = '_blank';
    ancorTag.download = 'CouponOrder.pdf';
    document.body.appendChild(ancorTag);
    ancorTag.click();
    document.body.removeChild(ancorTag);
