How to get started with Express

Worldpay has a highly scalable point of sale (POS) processing platform called Express, which is built around a comprehensive semi-integrated payment portfolio, Vantiv Integration Suite for Express. The Express interface payment processing platform supports multiple payment integration and implementation options, which include both a direct API or payment middleware solutions.


The Express API is a server-side web-service application where communication takes place over secure HTTPS links to the Internet. Secure data transfer is handled via XML or SOAP depending on the preference of the developer.  XML is the preferred interface option because new functionality and enhancements are no longer implemented using SOAP.


Our payment middleware solutions come in a variety of options including triPOS, Mobile SDK and Hosted Payments to best fit your payments development needs depending on implementation options, supported specialty verticals and simplified card brand and compliance certifications.


Find the toolkits listed below that developers need to build in-store, eCommerce and mobile applications designed for a variety of payment types and verticals. Worldpay O.N.E. provides access to industry standard tools, documentation and code that are available for testing in an integrated sandbox using production test simulators.


Express Supports



Payment Middleware Solutions



A turnkey payment processing application designed to process both magnetic stripe and EMV transactions. triPOS easily interfaces with custom business management software. The application supports domestic debit and credit transaction processing through the Express platform.


Mobile SDK

For those who desire a fully integrated mobile solution, the TransForm Mobile SDK simplifies the marriage of the Express interface and the business management software application extended to the mobile device, ensuring both connectivity and security.


Hosted Payments

A fully integrated, scope reducing eCommerce solution, designed to help ISVs and their customers avoid the significant cost and effort of achieving PCI compliance. With Hosted Payments, your application collects the non-sensitive data needed to perform a payment transaction, while Vantiv Integrated Payments handles all of the sensitive cardholder data. View the Express API for more details about how to integrate a hosted page into your application.
