This documents Transaction Request APIs.

  1. Three Step Redirect API: The Three Step Redirect is the preferred API for customized web-based payment processing. Using this integration method significantly reduces a merchant’s PCI footprint without sacrificing end-user look and feel. This method is required when using Verified by Visa/Mastercard SecureCode (Payer Authentication).
  2. Direct Post API: The Direct Post method is the simplest integration method for both web-based and non web-based payment applications, however, merchants using this integration method should have passed a PCI vulnerability scan before use.
  3. js: Collect.js provides access to a popup form which securely captures payment data and generates a “token.” The token is then used with the Direct Post API instead of raw credit card or bank account data. The popup form is technically a separate page hosted by the gateway, so no payment information touches the merchant’s site. This allows merchants to minimize their PCI-compliance footprint, with minimal changes to the customer experience.
  4. Mobile SDK: The Mobile SDK supports iOS and Android based devices. These SDKs include a mobile card reader library which simplifies integrations for applications requiring encrypted mobile card readers. Additionally, an end-to-end encryption library is included, allowing merchants to send both swiped and keyed-in payment information without ever touching any sensitive data.
  5. EMV Chip Card SDK: The EMV Chip Card SDK is a Windows-based software development kit that abstracts the complexities of interfacing directly with hardware terminals.
