useApi()
React Hook

Returns the full API object that was passed in to your extension when it was created. Depending on the extension target, this object can contain different properties.

For example, the purchase.checkout.cart-line-item.render-after extension target will return the CartLineDetailsApi object. Other targets may only have access to the StandardApi object, which contains a basic set of properties about the checkout.

For a full list of the API available to each extension target, see the ExtensionTargets type.

Note

> As of version 2025-10, you no longer need this hook. The full API object is accessible via > the global shopify object.

RenderExtensionTargets

A UI extension will register for one or more extension targets using `shopify.extend()`. An extension target in a UI extension is a plain JavaScript function. This function receives some API for interacting with the application, and is expected to return a value in a specific shape. The input arguments and the output type are different for each extension target.

Analytics

publish
Publish method to emit analytics events to [Web Pixels](/docs/apps/marketing).
```
(name: string, data: Record<string, unknown>) => Promise<boolean>
```
visitor

SubscribableSignalLike

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).

```
SubscribableSignalLike<boolean>
```
intercept
Installs a function for intercepting and preventing progress on checkout. This returns a promise that resolves to a teardown function. Calling the teardown function will remove the interceptor. To block checkout progress, you must set the [block_progress](/docs/api/checkout-ui-extensions/configuration#block-progress) capability in your extension's configuration. If you do, then you're expected to inform the buyer why navigation was blocked, either by passing validation errors to the checkout UI or rendering the errors in your extension.
```
(interceptor: Interceptor) => Promise<() => void>

All possible steps a buyer can take to complete the checkout. These steps may vary depending on the type of checkout or the shop's configuration.

Interceptor

A function for intercepting and preventing navigation on checkout. You can block navigation by returning an object with `{behavior: 'block', reason: InvalidResultReason.InvalidExtensionState, errors?: ValidationErrors[]}`. If you do, then you're expected to also update some part of your UI to reflect the reason why navigation was blocked, either by targeting checkout UI fields, passing errors to the page level or rendering the errors in your extension.

translate
Returns translated content in the buyer's locale, as supported by the extension. - `options.count` is a special numeric value used in pluralization. - The other option keys and values are treated as replacements for interpolation. - If the replacements are all primitives, then `translate()` returns a single string. - If replacements contain UI components, then `translate()` returns an array of elements.
