That only works if you know the Attachment ID.
The GET /Static allows us to get the metadata for all attachments. So for example my attachments are related to my documents. When i store the attachments I store the id of the document as part of the attachment's metadata.
So if i can do a GET /Static from the client api, i can load a document then load /Static and get all the attachments related to the document. This will allow me to generate an N number of links on our app, so the user can download the attachments.
Thoughts?
