Google Pay element styles and customization

All Google Payment buttons on your site must adhere to the Google Pay Brand Guidelines, which include, but aren't limited to, the following requirements. Digital River provides the following Google Pay button options for clients to add to the product page/checkout page (express checkout) or payment options page.

Configure Button Type
HTML Code

Configure Button Color

HTML Code

buttonColor: "dark"

When configuring a button, note the following:

  • The button color must contrast with the background color of the area that surrounds it.

  • Always maintain the minimum clear space of 8 density-independent pixels (dp) on all sides of the payment button. Ensure the clear space is never broken with graphics or text.

  • Observe the Google Pay Dos and Don'ts.
