Properties

Property	Type	Remarks
buttonColor	`"default" \| "black" \| "white"`	Optional. `"default"`/`"black"` buttons are suitable to be used on light colored backgrounds, with `"white"` being appropriate for dark colored backgrounds. Default value `"default"`.
buttonLocale	`string`	Optional. This ISO 639-1 code represents the desired button language. Supported locales include `en`, `ar`, `bg`, `ca`, `cs`, `da`, `de`, `el`, `es`, `et`, `fi`, `fr`, `hr`, `id`, `it`, `ja`, `ko`, `ms`, `nl`, `no`, `pl`, `pt`, `ru`, `sk`, `sl`, `sr`, `sv`, `th`, `tr`, `uk`, and `zh`. Default value is determined by the browser/operating system locale.
buttonSizeMode	`"static" \| "fill"`	Optional. `"static"` buttons will be sized according to the translated `buttonType`. `"fill"` buttons will be styled according the the element's size. Use this mode when resizing the button with CSS `width` and `height` properties. Default value `"static"`.
buttonType	`"book" \| "buy" \| "checkout" \| "donate" \| "order" \| "pay" \| "plain" \| "subscribe" \| "long" \| "short"`	Optional. Displays their respective prompts (localized based on the user's browser settings) with the Google Pay logo. The `"plain"` button only displays the Google Pay logo. `"long"` and `"short"` button types have been renamed to `"buy"` and `"plain"`, but are still valid button types for backwards compatability. Default value `"buy"`.
buttonRadius	`number`	Optional. Specifies the button corner radius in pixels. The minimum is 0 and the maximum depends on the height of the button. If the height is 40px (default height) then the maximum value for the `buttonRadius` is 20.
buttonBorderType	`"no_border" \| "default_border"`	Optional. `"no_border"` No border is displayed around the button. `"default_border"` A thin border is displayed around the button. Default value `"default_border"`.
environment	`"TEST" \| "PRODUCTION"`	Required. The Google Pay environment to target. Note: in the `"TEST"` environment, fake payment credentials are returned. In order to use the `"PRODUCTION"` environment, your website must be registered with Google Pay. This can be done through the Google Pay Business Console.
existingPaymentMethodRequired	`boolean`	Optional. When set to `true` (and `environment` is `Production`), the Google Pay button will only be displayed if the user already has an existing payment that they can use to make a purchase. Default value `false`.
paymentRequest	`PaymentDataRequest`	Required. Request parameters that define the type of payment information requested from Google Pay. See `PaymentDataRequest` reference for more information.

Callbacks/events

Callback	Arguments	Remarks
onCancel cancelCallback	reason	Invoked when a user cancels or closes the Google Pay payment sheet. Also raised as event `"cancel"`.
onClick clickCallback	event	Invoked when the Google Pay button is clicked, before the payment sheet is displayed. Display of the payment sheet can be prevented by calling `event.preventDefault()`.
onError errorCallback	reason	Invoked when an error is encountered in the process of presenting and collecting payment options from the Google Pay payment sheet. Also raised as event `"error"`.
onLoadPaymentData loadPaymentDataCallback	paymentData	Invoked when a user has successfully nominated payment details. This callback receives the `PaymentData` response which includes the `PaymentMethodData` that can be sent to supported payment processors. Also raised as event `"loadpaymentdata"`.
onPaymentAuthorized paymentAuthorizedCallback	paymentData	Invoked when a user chooses a payment method. This callback should be used to validate whether or not the payment method can be used to complete a payment. This would be typically used to perform pre-authorization to ensure that the card is valid and has sufficient funds. Note that in order to use this callback `paymentRequest.callbackIntents` must include `PAYMENT_AUTHORIZATION`. See payment authorization reference for more information.
onPaymentDataChanged paymentDataChangedCallback	intermediatePaymentData	Invoked when payment the user changes payment data options including payment method, shipping details, and contact details. This callback can be used to dynamically update `transactionInfo` when payment details, shipping address, or shipping options change. Note that in order to use this callback `paymentRequest.callbackIntents` must include either `SHIPPING_ADDRESS` or `SHIPPING_OPTION`. See payment data changed reference for more information.
onReadyToPayChange readyToPayChangeCallback	result	Invoked when the user's `isReadyToPay` state changes. This callback can be used to change the application's behaviour based on whether or not the user is ready to pay. Note that when `existingPaymentMethodRequired` is `true`, you will need to inspect both `result.isReadyToPay` and `result.paymentMethodPresent` to determine if the user `isReadyToPay` and has a `paymentMethodPresent`. Alternatively, `result.isButtonVisible` can be used to determine whether or Google Pay button will be displayed. `existingPaymentMethodRequired` is taken into account with `result.isButtonVisible`. Also raised as event `"readytopaychange"`.
