Customization

Visual customization: Colors, shapes, specific UI components

You can customize the React Native Unified Checkout to supports visual customization, which allows you to match the design of your app

Appearance

Use the appearance parameter to customize colors, fonts, and more when calling initPaymentSheet() or via the options prop when using PaymentWidget.

Colors

Customize the colors in the mobile Payment Element by modifying the color categories. Each color category determines the color of one or more components in the UI. For example, primary defines the color of the Pay button

Color Category	Usage
primary	Primary defines the color of the Pay button and selected items
background	The color used for the background of your Payment page
componentBackground	The color used for the background of inputs, tabs, and other components
componentBorder	The color used for the external border of inputs, tabs, and other components in your PaymentSheet
componentDivider	The color used for the internal border (meaning the border is shared with another component) of inputs, tabs, and other components in your PaymentSheet
primaryText	The color of the header text in your Payment page
secondaryText	The color of the label text of input fields
componentText	The color of the input text in your PaymentSheet components, such as the user's card number or zip code
placeholderText	The color of the placeholder text of input fields
icon	The color used for icons in your Payment Sheet, such as the close (x) button
error	The color used to indicate errors or destructive actions in your Payment Sheet

appearance: {
   colors: {
   primary: '#F8F8F2',
   background: '#ffffff',
   componentBackground: '#E6DB74',
   componentBorder: '#FD971F',
   componentDivider: '#FD971F',
   primaryText: '#F8F8F2',
   secondaryText: '#75715E',
   componentText: '#AE81FF',
   placeholderText: '#E69F66',
   icon: '#F92672',
   error: '#FF0000',
 }
}

Note : To support dark mode, pass maps for both light and dark colors maps to colors

colors: {
   light:{
      primary: '#F8F8F2',
      background: '#00FF00',
      componentBackground: '#E6DB74',
      componentBorder: '#FD971F',
      componentDivider: '#FD971F',
      primaryText: '#F8F8F2',
      secondaryText: '#75715E',
      componentText: '#AE81FF',
      placeholderText: '#E69F66',
      icon: '#F92672',
      error: '#F92672',
   },
   dark: {
      primary: '#00ff0099',
      background: '#ff0000',
      componentBackground: '#ff0080',
      componentBorder: '#62ff08',
      componentDivider: '#d6de00',
      primaryText: '#5181fc',
      secondaryText: '#ff7b00',
      componentText: '#00ffff',
      placeholderText: '#00ffff',
      icon: '#f0f0f0',
      error: '#0f0f0f',
    },
 },

Shapes

Customize the border radius, border width, and shadow used across the payment UI.

Shape Category	Usage
borderRadius	Corner radius of input fields, tabs, and other components.
borderWidth	Border thickness across input fields, tabs, and other components.

shapes: {
    borderRadius: 10,
    borderWidth: 1,
  },

Specific UI components

The sections above describe customization options that affect the mobile Payment Element broadly, across multiple UI components. We also provide customization options specifically for the primary button (for example, the Pay button).

Customization options for specific UI components take precedence over other values. For example, primaryButton.shapes.borderRadius overrides the value of shapes.borderRadius.

Primary Button

Overrides global colors and shapes for the primary button (e.g. the Pay button). Takes precedence over global values.

primaryButton: {
    colors: {
      background: '#000000',
      text: '#ffffff',
      border: '#ff00ff',
    },
    shapes: {
      borderRadius: 10,
      borderWidth: 1.5,
    },
  },

Google Pay Button

googlePay: {
  buttonType: 'BUY',   // BUY | BOOK | CHECKOUT | DONATE | ORDER | PAY | SUBSCRIBE | PLAIN
  buttonStyle: {
    light: 'dark',
    dark: 'light',
  }
}

Apple Pay Button

applePay: {
  buttonType: 'buy',   // buy | setUp | inStore | donate | checkout | book | subscribe | plain
  buttonStyle: {
    light: 'black',    // white | whiteOutline | black
    dark: 'white',
  }
}

Now you can test the payments on your app and go-live!
