Wallet top-up by card scheme

Card payment for a merchant payment scheme

General description

The SDK.finance platform includes an integration with CyberSource to support 3-D Secure (3DS) authentication and card authorization. This integration is used in the following flows:

  • Wallet top-up by card in the SDK.finance mobile application.

  • Card payment for a Merchant Payment created in the SDK.finance Merchant Portal.

The integration consists of both back-end and front-end components. When the SDK.finance mobile application is used, it includes the built-in front-end part. If only the SDK.finance back-end is used, the front-end component must be developed separately.

The front-end part covers Device Data Collection and the 3DS iFrame required for secure payment processing.
