Order Status Localization API

The Order Status Localization API provides access to the buyer's locale, currency, time zone, country, and market context on the Order status page. Use this API to read localization details and adapt your extension's content to the buyer's region.

Shopify's i18n translation and formatting helpers aren't available on the Order status page. To translate strings, use extensionLanguage from this API with your own translation files. To format numbers, currencies, and dates, use web-standard APIs like Intl.NumberFormat.

Anchor to Use casesUse cases

Format currency values: Read the buyer's currency to correctly format money amounts displayed in your extension.
Adapt content by region: Show region-specific content, such as local support contact information, based on the buyer's country and market.
Load translations: Determine which translation file to load for your extension based on the best available language match, falling back to your default locale.

Anchor to PropertiesProperties

The shopify global object provides the buyer's locale, currency, time zone, country, and market context. Access the following properties on shopify to read localization details and adapt your extension's content to the buyer's region.

Anchor to localization localization required: The buyer's locale, currency, time zone, country, and market context for the order. Use these values to adapt your extension's content to the buyer's region. For formatted dates, numbers, and translated strings, use the Localization API instead.

OrderStatusLocalization

Provides raw localization data only. The `i18n` translation and formatting helpers from the Localization API aren't available on order status targets.

country
The country associated with the order, carried over from the cart context where it was used to contextualize the storefront experience. Use this value to display region-specific content such as local support information or regional policies. The value is `undefined` if the buyer's country is unknown.
```
SubscribableSignalLike<Country | undefined>
```
currency
The currency used to display money amounts on the **Order status** page. Use this value to format prices and totals in the buyer's expected currency.
```
SubscribableSignalLike<Currency>
```
extensionLanguage
The best available language match for your extension based on the buyer's language. If the buyer's language is `fr-CA` but your extension only supports `fr`, this returns `fr`. If your extension doesn't support any variant of the buyer's language, this falls back to your extension's default locale (the `.default.json` translation file). Use this value to load the correct translation file for your extension.
```
SubscribableSignalLike<Language>
```
language
The language the buyer sees on the **Order status** page. This reflects the language selected by the buyer or determined by their browser settings, and may differ from the languages your extension supports.
```
SubscribableSignalLike<Language>
```
market
The [market](/docs/apps/build/markets) associated with the order, carried over from the cart context. Markets group countries and regions with shared pricing, languages, and domains. The value is `undefined` if the market is unknown.
```
SubscribableSignalLike<Market | undefined>
```
timezone
The buyer's time zone, derived from their browser or account settings. Use this value to format dates and times relative to the buyer's local time.
```
SubscribableSignalLike<Timezone>
```

SubscribableSignalLike

Represents a reactive signal interface that provides both immediate value access and subscription-based updates. Enables real-time synchronization with changing data through the observer pattern. This interface extends `ReadonlySignalLike` with deprecated fields that are still supported for backwards compatibility.

current
The current value of the signal. Equivalent to `.value`, accessing this property subscribes to changes when used in a reactive context.
```
T
```
destroy
Cleans up the subscription and releases any resources held by this signal. After calling `destroy()`, the signal stops receiving updates from the main thread.
```
() => Promise<void>
```
subscribe
Subscribes to value changes and calls the provided function whenever the value updates. Returns an unsubscribe function to clean up the subscription. Use to automatically react to changes in the signal's value.
```
(fn: (value: T) => void) => () => void
```
value
The current value of the signal. This property provides immediate access to the current value without requiring subscription setup. Use for one-time value checks or initial setup.
```
T
```
