Payment flow experience

From order creation to payment completion, Waffo provides a clear, smooth, and standardized interaction flow.
1

The user browses goods or services on the merchant’s site and clicks the “Checkout” button. The merchant backend calls the Waffo API to create a Payment Session or Subscription.
  • Generates a unique Order ID
  • Presets amount and currency

UI customization options

To ensure the checkout blends seamlessly with your brand, Waffo offers granular customization options. You can control the look and feel via three methods:
  • Merchant Portal: Visual Configuration, No Code Required. Upload logo, configure brand colors and interface styling, customize payment method order—all with real-time preview in the merchant dashboard.
  • API Parameters: Server-side dynamic control. Pass configuration parameters when creating a Session to display different interfaces for different user groups (e.g., VIPs).
  • Client SDK: Frontend fine-grained control. (Embedded only). Define specific CSS properties like fonts, spacing, and border radius via JavaScript objects.

Multi-language support

Waffo Checkout aims to provide a payment experience that feels like a native local application for global users. To deliver the most precise localization, Waffo Checkout intelligently presets and presents the most suitable interface language based on the region of the selected payment method.
Example: When a user selects Alipay, the system automatically adapts to a Simplified Chinese interface; when selecting TrueMoney, it adapts to Thai, ensuring users complete payments in their most familiar language environment.
Example languages supported (non-exhaustive): English, Thai, Japanese, Simplified Chinese, Traditional Chinese, Spanish, Bahasa Indonesia, and more.
