## ExpressCheckoutElement

Use the `ExpressCheckoutElement` from `@stripe/react-stripe-js/checkout` to accept payments through one-click payment buttons.

The component must be rendered inside a [CheckoutProvider](/js/react_stripe_js/checkout/checkout_provider.md).

### Props

- `id` (string)
  Sets the DOM `id` attribute on the rendered Element container. Use this to
target the Element for styling or testing.

- `className` (string)
  Applies custom CSS classes to the Element container.

- `options` (object)
  Express Checkout Element initialization options.

  - `buttonHeight` (number)
    By default, the height of the buttons are 44px.

You can override this to specify a custom button height in the range of 40px-55px.

  - `buttonTheme` (object)
    Specify the preferred button theme to use. By default, Elements determines the themes based on the specified [appearance option](/js/elements_object/create.md#stripe_elements-options-appearance).

    - `applePay` ('black' | 'white' | 'white-outline')

    - `googlePay` ('black' | 'white')

    - `paypal` ('gold' | 'blue' | 'silver' | 'white' | 'black')

    - `klarna` ('dark' | 'light' | 'outlined')

  - `buttonType` (object)
    Specify the preferred button type to display.

    - `applePay` ('add-money' | 'book' | 'buy' | 'check-out' | 'contribute' | 'donate' | 'order' | 'plain' | 'reload' | 'rent' | 'subscribe' | 'support' | 'tip' | 'top-up')
      Default is `plain`.

    - `googlePay` ('book' | 'buy' | 'checkout' | 'donate' | 'order' | 'pay' | 'plain' | 'subscribe')
      Default is `buy`.

    - `paypal` ('paypal' | 'checkout' | 'buynow' | 'pay')
      Default is `paypal`.

    - `klarna` ('continue' | 'pay')
      Default is `pay`.

  - `layout` (object)
    Specify how the buttons are arranged in a grid-like layout in the Express Checkout Element.
Elements determines the layout by using certain factors, such as available space, number of buttons, and the defined `layout` object.

    - `maxColumns` (number)
      Defines the maximum number of columns the Express Checkout Element can use to render. Default is `0`, meaning unlimited.

    - `maxRows` (number)
      Defines the maximum number of rows the Express Checkout Element can use to render. Default is `0`, meaning unlimited.

    - `overflow` ('auto' | 'never')
      Specify whether or not to always hide the overflow menu or allow Elements to determine when to show the overflow menu. Default is `auto`.
You can't specify both `overflow: 'never'` and set `maxRows` to a number greater than 0.

  - `paymentMethodOrder` (array)
    By default, the Express Checkout Element uses a dynamic ordering that optimizes payment method display for each user.

You can override the default order in which payment methods display in the Express Checkout Element with a list of payment method types.

If there are payment methods that will show that are not specified in `paymentMethodOrder`, they display after the payment methods you specify. If you specify payment methods that will not show, they are ignored.

  - `paymentMethods` (object)
    Besides your Dashboard configuration, the availability of payment methods in the Express Checkout Element is influenced by the CheckoutSession configuration. By default, it displays all available payment methods based on both configurations. When setting the paymentMethods option, the Express Checkout Element merges your specified options with the default logic to determine the final set of payment methods displayed.

    - `amazonPay` ('auto' | 'never')

    - `applePay` ('always' | 'auto' | 'never')
      Apple Pay has additional configurations
that determine when Stripe can show it. By default, Apple Pay shows when the customer
is using a supported platform and when we determine it's advantageous for your conversion.
This is the `auto` behavior.
If you want to always show Apple Pay when the customer is using a supported platform,
you can set its property in `paymentMethods` to `always`.

    - `googlePay` ('always' | 'auto' | 'never')
      Google Pay has additional configurations
that determine when Stripe can show it. By default, Google Pay shows when the customer
is using a supported platform and when we determine it's advantageous for your conversion.
This is the `auto` behavior.
If you want to always show Google Pay when the customer is using a supported platform,
you can set its property in `paymentMethods` to `always`.

    - `link` ('auto' | 'never')

    - `paypal` ('auto' | 'never')

- `onConfirm` (function) **required**
  Triggered when the Element fires a confirm event. Use this to handle payment confirmation.

- `onReady` (function)
  Callback called once the Element is fully rendered.
Recieves the [ready event payload](/js/element/events/on_ready.md#element_on_ready-handler).

- `onBlur` (function)
  Callback called when the Element loses focus.

- `onFocus` (function)
  Callback called when the Element receives focus.

- `onEscape` (function)
  Callback called when the escape key is pressed within the Element.

- `onLoadError` (function)
  Callback called when the Element fails to load.
