Metafields
API

Requires access to protected customer data for some properties.

The API for interacting with metafields.

Anchor to orderstatusapiOrderStatusApi

The API object provided to this and other customer-account.order-status extension targets.

Anchor to appMetafields appMetafields <[]> required: The metafields requested in the shopify.ui.extension.toml file. These metafields are updated when there's a change in the merchandise items being purchased by the customer.

Requires access to protected customer data.
Anchor to metafields metafields <[]> required: The metafields that apply to the current order. The actual resource on which these metafields exist depends on the source of the order:

If the source is an order, then the metafields are on the order.

If the source is a draft order, then the initial value of metafields are from the draft order, and any new metafields you write are applied to the order created by the checkout.

For all other sources, the metafields are only stored locally on the client creating the checkout, and are applied to the order that results from checkout.

These metafields are shared by all extensions running on checkout, and persist for as long as the customer is working on this checkout.

Once the order is created, you can query these metafields using the GraphQL Admin API

ReadonlySignalLike

Represents a read-only value managed on the main thread that an extension can subscribe to. Example: Checkout uses this to manage the state of an object and communicate state changes to extensions running in a sandboxed web worker. This interface is compatible with Preact's ReadonlySignal: https://github.com/preactjs/signals/blob/a023a132a81bd4ba4a0bebb8cbbeffbd8c8bbafc/packages/core/src/index.ts#L700-L709

subscribe
```
(fn: (value: T) => void) => () => void
