# mintNoteAttachmentUpload

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

## What it does

Get a short-lived, pre-authorized upload slot for a note attachment.

Template class (hand-derived v29).

## What happens

The file type and size are checked BEFORE any bytes move; risky types are refused unless scanning is enabled for your group.

## Who may call it

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

- Owner
- System Administrator
- Manager
- Associate Manager
- Warehouse Associate
- Sales Associate
- Cashier
- An API key whose scope allows `api:mintNoteAttachmentUpload`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [MintNoteAttachmentUploadInput](/types/MintNoteAttachmentUploadInput/) `MintNoteAttachmentUploadInput!` | yes | No further notes. |

## Returns

[NoteAttachmentUploadTicket](/types/NoteAttachmentUploadTicket/) `NoteAttachmentUploadTicket!` — The upload ticket: a short-TTL presigned PUT against the write-once blob key, PRE-TAGGED pending (the 7-day lifecycle reaps never-attached orphans). Bind the attachmentId via addNote before the TTL's practical window closes.

```graphql
mutation ExampleMintNoteAttachmentUpload($input: MintNoteAttachmentUploadInput!) {
  mintNoteAttachmentUpload(input: $input) {

  }
}
