# QR-Code-Designvorlage aktualisieren

> PATCH /qr-assets/template/{pk}/

Aktualisiert eine QR-Designvorlage, die diesem Konto gehört, auf dem **Management-API**-Host (`api.scanova.io`), authentifiziert mit Ihrem rohen Management-API-Schlüssel.

```
PUT   https://api.scanova.io/qr-assets/template/{pk}/
PATCH https://api.scanova.io/qr-assets/template/{pk}/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<ParamField path="pk" type="integer" required>
  Die `id` der Vorlage.
</ParamField>

Sowohl `PUT` (vollständiger Ersatz) als auch `PATCH` (partielles Update) werden unterstützt und akzeptieren dieselben Felder `name`/`pattern_info`/`image`, die unter [QR-Code-Designvorlage erstellen](/de/api-reference/management-api/qr-assets/template-create) dokumentiert sind.

<RequestExample>
  ```bash cURL theme={null}
  curl -X PATCH "https://api.scanova.io/qr-assets/template/12/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a" \
    -H "Content-Type: application/json" \
    -d '{ "name": "Winter Poster" }'
  ```
</RequestExample>

<ResponseExample>
  ```json 200 theme={null}
  {
    "id": 12,
    "name": "Winter Poster",
    "template_id": "a1b2c3d4e5f6",
    "template_type": "P",
    "template_type_display": "Poster",
    "pattern_info": "{\"dotStyle\":\"round\"}",
    "image": "https://cdn.scanova.io/upload/images/42/template-foo.png"
  }
  ```
</ResponseExample>

## `template_type` kann hier nicht geändert werden

`template_type` ist nur bei der Erstellung setzbar — wird er in einem `PUT`/`PATCH`-Body gesendet, wird er stillschweigend verworfen statt einen Fehler auszulösen, sodass die Vorlage ihren ursprünglichen Poster-/Normal-Typ ihr ganzes Leben lang behält. `404`, wenn `pk` keine Vorlage ist, die diesem Konto gehört.

    used to authenticate against it. Every path and request/response shape below

      description: >-
        Send your Management API key as the raw value of the Authorization
        header — no "Bearer " or "Token " prefix, and no other characters.
        Example: `Authorization: 401f7ac837da42b97f613d789819ff93537bee6a`. A
        header containing more than one space-separated part is rejected
        outright. Requests also require the request's Host header to be the
        management API host (e.g. api.scanova.io) — the same key sent to the
        regular API host will not authenticate.
