<Snippet file="localization-common.mdx" />

## How to Adjust the Currency and Language

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

```tsx {3,16} theme={null}
<CrossmintProvider apiKey="_YOUR_CLIENT_API_KEY_">
    <CrossmintEmbeddedCheckout
        locale="es-ES" // Change locale to Spanish
        lineItems={{
            collectionLocator: "crossmint:_YOUR_COLLECTION_ID_",
            callData: {
                // your callData args
            },
        }}
        payment={{
            crypto: {
                enabled: true,
            },
            fiat: {
                enabled: true,
                defaultCurrency: "eur", // Change default currency to be Euro
            },
        }}
    />
</CrossmintProvider>
```
