Overview

With W3C Payment Request, you can offer Samsung Pay as a payment option on your website for customers making purchases on Samsung mobile devices. This integration is built on the W3C Payment Request API, which provides a standardized browser-based payment experience.

The following sections provide all the information you need to integrate W3C Payment Request:

• Prerequisites

  Defines the requirements for using the W3C Payment Request service.

• Sample code

  Offers an end-to-end sample code demonstrating a complete implementation from set-up to payment result handling.

User experience

The W3C Payment Request integration supports 2 user experience models, depending on how you choose to present Samsung Pay on your website:

• Standard W3C model

  In the standard W3C model, your website presents multiple payment methods, including Samsung Pay. When the customer taps your checkout button, the browser displays the standard payment sheet. The customer can then select a payment method or add a new payment instrument, such as a debit or credit card. Selecting Samsung Pay opens the Samsung Pay payment sheet to complete the transaction.

  

• Branded Samsung Pay model

  If your website offers Samsung Pay as the only available payment method, you can use the branded Samsung Pay model where your website displays the Buy with Samsung Pay button instead of a generic checkout button. When the customer taps this button, the Samsung Pay payment sheet is displayed directly. If additional information is required, such as a shipping address or contact details, the browser first presents the standard payment sheet to collect the information before proceeding to the Samsung Pay payment sheet. If you need to offer multiple payment methods, use the standard W3C model.
