Card Payments SDK

SDK Card Payments

Configuration

For configuration code samples, see our Configuration Code for SDKs article.

Authorization

We highly recommend sanitizing the cardholder data before sending it in the request. For example, check if the card number is valid and the expiry date is in the future. Our JavaScript Library on GitHub contains a handy set of functions to help you do this.

Validate (Open To Buy)

Validate is also referred to as 0$ auth.

Credit

Credit is also referred to as a Refund or Blind Refund (depending on region).

For security reasons this request type is not enabled by default. It must be requested by one of the listed contacts on your account with us.
