# Support Download

`GET /api/support/attachments/{attachment_id}`

## Request

- Base URL: `https://api.advisorppc.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.advisorppc.com/api/support/attachments/{attachment_id}`
- Auth: none declared

Serve one file back to whoever holds a link we minted for it.

A presigned link rather than a re-derived owner, and that is a decision
rather than a shortcut: a download is a navigation, a navigation carries no
header, and the signed runtime handle is the only thing that identifies a
customer of mcp.advisorppc.com here. The reasoning, and what bounds the
link instead, is in support_attachments.DOWNLOAD_TTL_S.

Every failure is the SAME 404. A 403 for "wrong signature" against a 404
for "no such file" would turn this route into an oracle for which ids
exist.
