It would be great to be able to generate a permalink to an attachment which works in the same way as the existing permalinks to tasks. The idea is to allow links to be embedded into other documents or software systems which when clicked will open Wrike in a browser, authenticate the user, then open the attachment directly in the Wrike attachment preview window.
I have a script using the API which will download the attachments and upload them into another system, but it would be much better if I could use links instead so that there is only one source of truth for the file. The existing API feature for attachment URLs provides public URLs which are only valid for 24 hours. I am looking for private URLs which will last forever (i.e. a permalink)
