# Theme aktualisieren

> PATCH /theme/{slug}/update/

Aktualisiert ein Theme, das diesem Konto gehört, auf dem **Management-API**-Host (`api.scanova.io`), authentifiziert mit Ihrem rohen Management-API-Schlüssel.

```
PATCH https://api.scanova.io/theme/{slug}/update/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<ParamField path="slug" type="string" required>
  Der `slug` des Themes.
</ParamField>

<ParamField body="name" type="string">
  Neuer Theme-Name.
</ParamField>

<ParamField body="config_json" type="object">
  Neue Design-Tokens nach dem ThemeConfigV2-Schema.
</ParamField>

<ParamField body="clear_conflicting_overrides" type="boolean">
  Wenn `true`, werden pro-QR-`theme_overrides`, die mit den von Ihnen geänderten Feldern in Konflikt stehen, von jedem QR-Code entfernt, der dieses Theme derzeit verwendet — damit eine Änderung hier keine veralteten pro-QR-Überschreibungen hinterlässt, die sie verdecken.
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X PATCH "https://api.scanova.io/theme/user-42-ocean-breeze-a1b2c3/update/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a" \
    -H "Content-Type: application/json" \
    -d '{
      "config_json": { "color": { "accent": "#005f99" } },
      "clear_conflicting_overrides": true
    }'
  ```
</RequestExample>

<ResponseExample>
  ```json 200 theme={null}
  {
    "id": 7,
    "name": "Ocean Breeze",
    "slug": "user-42-ocean-breeze-a1b2c3",
    "description": "A cool blue palette.",
    "config_json": { "color": { "accent": "#005f99", "background": "#f0f8ff" }, "font": { "heading": "Inter" } },
    "schema_version": 2,
    "category_hints": ["website-url", "vcard"],
    "thumbnail_url": "https://cdn.scanova.io/themes/7/thumb.png",
    "is_system": false,
    "is_premium": false,
    "order": 0
  }
  ```
</ResponseExample>

Es wird nur `PATCH` unterstützt (kein `PUT`). Nur Ihre eigenen Nicht-System-Themes sind hier schreibbar — ein System-Theme oder das eines anderen Kontos liefert `404`, genau wie wenn es nicht existieren würde, obwohl [Theme abrufen](/de/api-reference/management-api/theme-manager/theme-retrieve) es lesen kann. `400`, wenn `config_json` die Schemavalidierung nicht besteht.

  description: >-
    The complete Scanova Management API — every endpoint available at
    api.scanova.io (QR codes, folders, tags, leads, forms, analytics, plans,
    shared users & roles), plus the token-creation and usage-stats endpoints
    used to authenticate against it. Every path and request/response shape below
    was verified live against a real API key and the actual running backend
    (Phase 7, 2026-08-16) — not guessed from reading urls.py alone.

      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.
