# mintNoteAttachmentDownload

mutation · in the family [Work and notes](/reference/work-and-notes/)

## What it does

Get a short-lived download link for a note attachment.

Mint a short-TTL presigned DOWNLOAD for one note attachment: authz through the target-construct read; scanned-prefix blobs gate on the GuardDutyMalwareScanStatus tag (NO_THREATS_FOUND serves · tag-absent = scan-in-progress refuses politely · THREATS_FOUND refuses + the event · UNSUPPORTED/ACCESS_DENIED/FAILED refuse FAIL-CLOSED naming the status); unscanned-prefix blobs skip the gate (risky types never landed there — the routing). Template class (hand-derived v29).

## What happens

Files that require virus scanning only serve after a clean verdict — a flagged file refuses loudly.

## Who may call it

Capability area: **Work and notes** — Tasks, notes, messages, dashboards and the everyday tools every staff member keeps.

## Arguments

| Name | Type | Required | Notes |

## Returns

[NoteAttachmentDownloadTicket](/types/NoteAttachmentDownloadTicket/) `NoteAttachmentDownloadTicket!` — The download ticket: a short-TTL presigned GET (the verdict gate already passed for scanned-prefix blobs).
