| Variable           | Possible Values                                                                                                                   | Description                                                                                                                                                              |

| `locale`           | `en-US` `de-DE` `es-ES` `fr-FR` `it-IT` `ja-JP` `ko-KR` `pt-PT` `ru-RU` `th-TH` `tr-TR` `uk-UA` `vi-VN` `zh-CN` `zh-TW` `Klingon` | Language selected for the email receipt.                                                                                                                                 |
| `payment.currency` | `usd` `aud` `eur` `gbp` `hkd` `inr` `jpy` `krw` `sgd` `vnd`                                                                       | Currency for the payment quote. The original price of the collection will be automatically converted to the selected currency using the most recent bank exchange rates. |

<Note>
  Localization is not supported for stablecoins. While `payment.crypto.defaultCurrency` can be set to `usdc` or other
  supported tokens, localized stablecoins like `eurc` are not available.
</Note>

To customize the language use the property `locale` and for currency, set `currency` under the payment object. Here's an example:

```json {2,6} theme={null}
{
    "locale": "es-ES", // Price for receipt (e.g. Spanish customers)
    "payment": {
        "receiptEmail": "jsmith@example.com",
        "method": "card",
        "currency": "eur" // If collection is priced in USD, price returned for quote will be in EUR
    },
    "lineItems": [
        {
            "collectionLocator": "crossmint:76ced33d-fec8-4741-a69f-450f1ae09fa6",
            "callData": {
                "totalPrice": "<string>"
            }
        }
    ]
}
```

<Note>
  When implementing a headless checkout, you'll need to handle the display of localized content in your own UI based
  on the locale you've selected. The locale only affects the email receipt language, not the checkout interface built
  by you.
