# A download URL for a note's attachment

`GET /business/knowledge-hubs/{hubId}/attachments/{noteId}`

## Request

- Base URL: `https://api.tryfuse.ai/api/v1`
- URL: `https://api.tryfuse.ai/api/v1/business/knowledge-hubs/{hubId}/attachments/{noteId}`
- Auth: HTTP basic

Returns a presigned download URL for the document attached to a note, together with the stored file name, MIME type and size. The URL is valid for one hour; request a fresh one when it expires. Readable by you and your teammates. A note that has no document answers 404 `ATTACHMENT_NOT_FOUND`, and a note id the hub does not have answers 404 `NOTE_NOT_FOUND`.

Errors:
- `404` `KNOWLEDGE_HUB_NOT_FOUND` — No hub with that id, it was deleted, or it belongs to another team.
- `404` `NOTE_NOT_FOUND` — No note with that id on this hub.
- `404` `ATTACHMENT_NOT_FOUND` — The note has no document attached.
- `422` `VALIDATION_FAILED` — hubId or noteId is not a 24-character hex id.
- `429` `RATE_LIMITED` — More than 30 knowledge-hub/campaign requests in a minute (or 1000 in a day). Knowledge hubs share the campaigns bucket.

Requires one of the following token scopes: campaigns.
