# Actualizar un tema

> PATCH /theme/{slug}/update/

Actualiza un tema propiedad de esta cuenta, en el host de la **API de gestión** (`api.scanova.io`), autenticado con su clave de API de gestión sin procesar.

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

<ParamField path="slug" type="string" required>
  El `slug` del tema.
</ParamField>

<ParamField body="name" type="string">
  Nuevo nombre del tema.
</ParamField>

<ParamField body="config_json" type="object">
  Nuevos tokens de diseño, siguiendo el esquema ThemeConfigV2.
</ParamField>

<ParamField body="clear_conflicting_overrides" type="boolean">
  Cuando es `true`, elimina las `theme_overrides` por QR que entren en conflicto con los campos que está cambiando de todos los códigos QR que actualmente usan este tema — para que una edición aquí no deje anulaciones por QR obsoletas que la ensombrezcan.
</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>

Solo se admite `PATCH` (sin `PUT`). Aquí solo son escribibles sus propios temas que no sean del sistema — un tema del sistema o el de otra cuenta devuelve `404`, igual que si no existiera, aunque [Obtener un tema](/es/api-reference/management-api/theme-manager/theme-retrieve) pueda leerlo. `400` si `config_json` no supera la validación del esquema.

  title: Scanova Management API (v2)
  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.

        only (no PUT). Pass `clear_conflicting_overrides: true` to strip per-QR
        `theme_overrides` that conflict with the fields you're changing from
        every QR code using this theme.

      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.
