# Update the classic theme

Endpoint: `https://api.youcan.shop/themes/classic`

Method: `PUT`

Changes the customization of the classic theme. The change is live on the store at once, there is no draft.

## Required Scopes

* `edit-themes`

## Parameters

Send only what changes, in the shape of the [Get the classic theme](/store-admin/themes/classic-get) `settings`:

| Param Name          | Param Type | Description                                           | Required |
|---------------------|------------|-------------------------------------------------------|----------|
| `store_settings`    | object     | Header, notice bar, footer, fonts and breadcrumbs     | no       |
| `colors_settings`   | object     | The nine theme colors                                 | no       |
| `product_settings`  | object     | Product page toggles, texts and style colors          | no       |
| `checkout_settings` | object     | The checkout page look                                | no       |
| `pages_settings`    | object     | `home`: the full ordered list of homepage sections    | no       |

* An object merges key by key into the current settings.
* A list, such as `pages_settings.home` or a header items list, replaces the current list. Send every item of a list that you change.
* A key must exist in the current settings, and its value keeps its type: a number stays a number, `true`/`false` stays a boolean, an object stays an object and a list stays a list.
* A color is a hex value, such as `#1a2b3c`, or `transparent`.
* Only the `content` fields (notice bar, footer, text sections) take HTML. No field can contain scripts, event handlers or `javascript:` URLs. Fields other than `content` cannot contain `{` or `}`.

```json
{
    "colors_settings": { "primary": "#1a2b3c" },
    "store_settings": { "breadcrumbs": { "global": true } }
}
```

    "errors": {
        "colors_settings.primary": ["must be a hex color such as #1a2b3c"],
        "store_settings.made_up": ["unknown setting, GET /themes/classic lists every key"]
    }
}
