# ExpressCheckoutElement
> One-press Apple Pay and Google Pay buttons for a checkout — the OS payment sheet collects whatever the session still needs (the buyer's email, a shipping address for physical goods, a promo code where the seller offers entry) and one press finishes the purchase. It shares the checkout's entry slot with the full checkout element, so a handle mounts exactly one of the two: this button alone where the purchase is simple enough for a sheet to finish, or the full checkout surface for everything else. Renders only the wallets the buyer's device can actually pay with, using the served button art, and renders nothing where no wallet is available. A checkout the sheet cannot honestly finish — a waitlist join, a transfer, a form question only a page can ask — refuses loudly instead of rendering a doomed button.
This page documents `@whop/elements@1.0.0-beta.1` and `@whop/elements-react@1.0.0-beta.1`.
*Pre-release, not yet part of a stable release.*
Mounts inside [`Checkout`](/elements/beta/checkout/overview). Pass props and callbacks through the create options or React props.
**Exclusive.** `ExpressCheckoutElement` is an alternative to `CheckoutElement` in this Checkout handle. Mount one at a time. Destroy it before mounting another.
```tsx React theme={null}
import { WhopElements, Checkout, ExpressCheckoutElement } from "@whop/elements-react";
import { loadWhop } from "@whop/elements";
function Example() {
return (
);
}
```
```html JavaScript theme={null}
```
Example data. [Open the Playground](/elements/beta/checkout/overview#playground).
## Props
Which wallets may render — a filter over what the buyer’s device actually offers. The element never shows a wallet the device or the served matrix cannot back, and the render order stays best-native-first whatever order this lists. An empty list renders nothing (warned in dev builds). Defaults to `["apple_pay","google_pay"]`.
How the buttons stack. `auto` follows the element’s own container — stacked in narrow containers, side by side in wide ones; `horizontal` and `vertical` force one arrangement. Defaults to `"auto"`.
## Events
Pass callbacks in the create options or React props.
### `onLoaderStart`
Runs after the loading skeleton first paints and before `onReady`.
**Signature:** `(() => void)`
### `onReady`
Runs after the element's first complete paint.
**Signature:** `(() => void)`
### `onError`
Runs when the element fails to load or crashes. The fallback remains visible. Use `code` for programmatic handling. `sourceKey` identifies a failed host-state source.
**Signature:** `((e: { message: string; code?: string | undefined; sourceKey?: string | undefined; }) => void)`
## Methods
Call these on the handle returned by `create`, or through a React `ref`.
### `mount`
Mounts the element in `target` and starts loading. React components mount themselves.
**Signature:** `(target: string | HTMLElement) => void`
### `destroy`
Removes the element and releases its frame and subscriptions. You can call it more than once. React removes the element automatically.
**Signature:** `() => void`
### `update`
Merges new props into the mounted element. In React, change the component props instead.
**Signature:** `(options: Partial) => void`
## Styling
Style these parts through `appearance.classes`. Use camel case or kebab case for property names and include units. Page stylesheets can't reach the element's frame. The framework validates each declaration before injecting it.
