Customization

Customize your Web Unified Checkout

1. Layouts

Choose a layout that fits well with your UI pattern. There are two types of layout options as listed below. The layout defaults to accordion if not explicitly specified.

1.1 Accordion Layout

The accordion layout displays payment methods vertically using an accordion. To use this layout, set the value for layout to accordion. You also have the option to specify other properties, such as those shown in the following example:

var paymentElementOptions = {
  layout: {
    type: 'accordion',
    defaultCollapsed: false,
    radios: true,
    spacedAccordionItems: false
  },
}

var paymentElementOptions = {
  layout: 'accordion'
}

<PaymentElement id="payment-element" options={paymentElementOptions} />

1.2 Tabs Layout

The tabs layout displays payment methods horizontally using tabs. To use this layout, set the value for layout to tabs. You also have the option to specify other properties, such as tabs or collapsed:

var paymentElementOptions = {
  layout: 'tabs'
}

<PaymentElement id="payment-element" options={paymentElementOptions} />

2. Wallets

The wallet customization feature lets users configure payment options like Apple Pay, Google Pay, PayPal, and Klarna. It includes a walletReturnUrl for post-payment redirects and a style property to customize the wallet’s appearance, offering flexibility for seamless integration:

var paymentElementOptions = {
  wallets: {
    walletReturnUrl: `${window.location.origin}`,
    applePay: "auto",
    googlePay: "auto",
    payPal: "auto",
    klarna: "never",
    style: {
      theme: "dark",
      type: "default",
      height: 55,
      buttonRadius: 4,
    },
  },
}

<PaymentElement id="payment-element" options={paymentElementOptions} />

Variable	Description	Values
`walletReturnUrl: string`	Defines the URL to redirect users to after completing a payment	This will take a URL string as its value
`applePay: showType` `googlePay: showType` `payPal: showType` `klarna: showType`	Determines the visibility of Apple Pay, Google Pay, PayPal, and Klarna	`showType` can take two values: • `"auto"`: Display when supported • `"never"`: Always hidden

4. Rules

The rules option is a map of CSS-like selectors to CSS properties, allowing granular customization of individual components. After defining your theme and variables, use rules to seamlessly integrate Elements to match the design of your site. The selector for a rule can target any of the public class names in the Element, as well as the supported states, pseudo-classes, and pseudo-elements for each class. For example, the following are valid selectors:

.Tab, .Label, .Input, .InputLogo, .SaveWalletDetailsLabel, .OrPayUsingLabel, .TermsTextLabel, .InfoElement, .OrPayUsingLine
.Tab:focus
.Input--invalid, .Label--invalid, .InputLogo--invalid
.Input::placeholder
.billing-section, .billing-details-text
.Input--empty, .InputLogo--empty

Each class name used in a selector supports an allowlist of CSS properties that you specify using camel case (for example, boxShadow for the box-shadow property).
