Downloading a Draft Form Attachment

To download a single file, use this endpoint. The appropriate Content-Disposition (attachment with a filename or Dataset name) and Content-Type (based on the type supplied at upload time, or text/csv in the case of a linked Dataset, or application/octet-stream otherwise) will be given. This endpoint supports ETag, which can be used to avoid downloading the same content more than once. When an API consumer calls this endpoint, it returns a value in ETag header, you can pass this value in the header If-None-Match of subsequent requests. If the file has not been changed since the previous request, you will receive 304 Not Modified response otherwise you'll get the latest file.
