# Update a template attachment

```http
PUT https://secure.yoprint.com/v2/api/store/{team_slug}/setting/message_template/{hash_id}/internal_attachment/{id}
```

- API version: v2
- Operation ID: `v2_public_message_template_internal_attachment_update_put`
- Section: Team settings › [Message template attachments](https://developer.yoprint.com/reference/message-template-attachments.md)
- Web page: https://developer.yoprint.com/reference/message-template-attachments/v2-message-template-internal-attachment-update-put/
- Authentication: `Authorization: Bearer YOUR_API_KEY`

Changes an attachment's `name`, `detail` or `options`. `options` are merged into the saved ones. The type and file can't change: delete it and add a new one.

Use PUT. PATCH has no rules and fails with 500.

## Permission

Needs the Manage Settings permission. The team owner always has it.

## Path parameters

- `team_slug` (string, required): Your team slug, shown as Team ID next to your API key in Profile. Example `your-team`.
- `hash_id` (string, required): The message template. Its hash id from an earlier answer; there is no unique key for it. Example `DVubREua5aJkwh`.
- `id` (string, required): The attachment, from the template's attachment list. Its hash id from an earlier answer; there is no unique key for it. Example `80qLp4P9l2ftvL`.

## Request body

Content type `application/json`, required.

Fields:

- `detail` (string, optional)
- `name` (string, optional)
- `options` (object, optional)
  - `show_mockup` (boolean, optional): For `so_jobs_with_mockup` and `so_jobs_without_mockup`: `true` puts each job's mockup pages in the job sheets, `false` leaves them out. It overrides the type's own choice. Text such as `"true"` or `"off"` is accepted too; any other value is refused with 422 `validation_failed`. Other types ignore it.

### Example request

```bash
curl -X PUT 'https://secure.yoprint.com/v2/api/store/your-team/setting/message_template/DVubREua5aJkwh/internal_attachment/80qLp4P9l2ftvL' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Accept: application/json' \
  -H 'X-Yoprint-Decimal-Format: exact-v1' \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "Order PDF"
  }'
```

  - `media_id` (string | null, required)
  - `name` (string | null, required)
  - `options` (string | null, required): The attachment's options as a JSON-encoded string, not an object: `"[]"`, or for job sheets `"{\"show_mockup\":true}"`. `"null"` for a `media` or `reference_media` file. Decode it before use.

## Errors

- `401` The API key is missing or wrong (`unauthenticated`).
- `403` You are not allowed to do this. `api_access_not_in_plan`: your team's plan doesn't include API access (Pro and above, with an active subscription or trial), so every request answers this until the team upgrades. When your role lacks the permission the operation needs, the body is only `{"message": "Insufficient Permission"}`. Other refusals use the error envelope, with `unauthorized` or `user_is_not_authorized`.
  - When: Your role lacks Manage Settings. The body is `{"message": "Insufficient Permission"}`, without the error envelope. Fix: Use the key of a member whose role has Manage Settings, or the owner's.
- `404` Not found. `page_not_found`: the team slug is unknown, you are not a member of the team, or an id in the path is not one of this team's. `code: null`, with a message that starts "No query results for": there is no record with that id.
  - When: The template or the attachment is not found. Fix: Use ids from the attachment list.
- `422` The request was refused and changed nothing. `validation_failed` lists what to fix in `error.fields`; other codes name a business rule, explained in `error.message`. A few checks answer with only `{"message": "..."}`. An operation that calls another service (a payment provider, a carrier, an accounting app) can answer `connect_timeout` ("Please retry again") when that service does not answer in time: the change may or may not have happened there, so read the record back before you retry.
