# Get a download link

`GET /api/v1/rest/email/messages/{id}/download-link`

## Request

- Base URL: `https://api.custodo.ai`
- URL: `https://api.custodo.ai/api/v1/rest/email/messages/{id}/download-link`
- Auth: HTTP bearer

A short-lived, signed URL for the raw `.eml` of one message, or for one of its attachments — pass `attachment_id` (from email_get) for the latter. Never a storage key: hand the URL straight to the user rather than trying to fetch it yourself.

**Examples**

- Give me a link to download that PEC
  `GET /api/v1/rest/email/messages/11111111-2222-4333-8444-555555555555/download-link`
- And a link for the invoice attached to it
  `GET /api/v1/rest/email/messages/11111111-2222-4333-8444-555555555555/download-link?attachment_id=66666666-7777-4888-8999-aaaaaaaaaaaa`

## Path parameters

- `id` string, uuid, required

## Query parameters

- `attachment_id` string, uuid
- `disposition` 'inline' | 'attachment'

## Headers

- `X-Tenant-Id` string, uuid

## Response `200`

Done. `data` is the tool’s own answer.

- RestResult
  - `ok` true, required
  - `data` unknown, required

## Other responses

- `400`: The arguments did not validate: `error.message` names the field, what it expects and what arrived.
- `401`: No API key, or one that is malformed, unknown, revoked or expired.
- `403`: The call never ran: the module is off for this organisation, the credential lacks the permission or the module, the tier does not cover it, or the tool is destructive and the key was not minted for that.
- `404`: Nothing with that id in this organisation.
- `422`: The tool ran and refused, in a sentence of its own (`TOOL_REFUSED`): the message says what to change. Retrying the same call will not help.
- `429`: The API key has spent its minute, or its day. Every request a key makes counts. See `Retry-After`.
