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

You can modify colors, fonts, and more by using the appearance parameter when you call initPaymentSheet().

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 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

you can customize the border radius, border width, and shadow used throughout the mobile Payment Element.

Shape Category	Usage
borderRadius	radius of the border of the input fields, tabs and other components of the payment page
borderWidth	width of the border used to 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.

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

    },
  },

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