Downloading a Form Attachment

To download a single file, use this endpoint.

The appropriate Content-Disposition (attachment with a filename) and Content-Type will be given. Content-Type will be either:

1. the type supplied at upload time, or if not supplied
2. a type derived from the file extension, or if none found
3. application/octet-stream

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.
