Upload a local file (PDF, image, XML, zip...) as an attachment for an issued or received document. Returns an attachment_token: pass it as data.attachment_token in a create/update tool to bind it to a document. Unbound tokens expire after a while, so upload right before creating/updating.

Remove the attachment from an issued or received document (the document itself is untouched). Irreversible. Note: the FIC API has been observed returning 500 on this endpoint; deleting the document or replacing the attachment via update (new attachment_token) are alternatives.
