We offer two awesome environments for creating your application. Knowing which one is best for you will save you time and provide the fastest path to doing what you do best - writing code.


We have provided you with a language agnostic environment that allows access to our rich set of features. Using our REST API you can choose whichever language and platform suits your needs. With simple HTTP POST, GET, PUT and DELETE calls, we make it possible to run credit card present (CP) or card not present (CNP) transactions. Additional functionality includes tools for managing customer payment accounts in a secure environment and the ability to enable recurring billing to automatically bill customers at specified intervals.

Integrated Payments Client SDK

In addition to the REST API set, we provide a full Software Development Kit (SDK) that removes the burden of having to write your own code to manage a card reader and allows you to develop native iOS and Windows applications. The Integrated Payments Client (IPC) SDK allows you to work in the natural environment of your chosen mobile device.

One of the more exciting features of the IPC SDK is that we have designed the interface so that you do not have to worry about getting EMV certified. Our SDKs are pre-certified, meaning that you can update your application and not have to certify or recertify. That puts money back in your pocket.

Which Environment Should I Choose?

Both environments allow access to the same features. However, they are intended for different purposes.

If you are going to be attaching a card reader to your application, the IPC SDK is likely your best shot. It handles all of the complex card reader interactions so that you can focus on developing your unique business logic. It also keeps you out of the loop of handling credit card information. This will eliminate all of the EMV certification costs and headaches that accompany developing EMV solutions. This also means you will likely be able to take the faster track of PCI DSS self-certification.

In order to provide this level of protection, the IPC SDK does require you to use one of our pre-certified card readers. Currently this is the Miura M010 for iOS, and the VX 805 for Windows. The list of supported devices will increase over time. You will need to use the REST API if you choose to use a device that is not supported. Because of the superior cost and code elimination advantages, we encourage you to consider whether your choice of card reader is negotiable.

If you do not have to support a card reader, the decision comes down to prgramming preferences. If you are developing on a mobile device and want native code libraries, the IPC SDK is the toolset for you. You can then use Swift/Objective C on iOS. If you want a more open platform that is not integrated into a native platform, then the REST API may be your best choice. The simplicity of a REST environment gives you development flexibility and allows you to use the language of your choice.

Integration Steps and Sandbox

Getting from code to live development is a simple, three step process.

First, you are going to need a safe place to test your code. The Worldpay Total platform offers a robust sandbox that simplifies the testing and certification process. The sandbox allows you to send API requests and view the responses in real time. The sandbox also comes equipped with a fully functional test simulator that allows you to create an assortment of test cases, which will ensure you are able to test against a wide variety of scenarios.

Before you can begin submitting API requests you will need your developer credentials and a test sandbox. Click on the link below called Signup for A Sandbox Account, answer a couple of questions and you will be given everything you need to start writing your app. You will be provided your developer credentials, a sandbox account to practice making calls, and your own Virtual Terminal to manage your account, get activity reports, and establish your own user defined test scenarios.

Your developer credentials consists of three pieces of information:

In order to make calls against the sandbox you will need to incorporate your developer credentials into your app. If you are using the REST API you will form a specially formatted string in the authentication header. In the IPC SDK, you simply set a couple of variables. This is covered in the documentation for each of these environments.

Once you have developed and tested your app and are ready to unleash its awesomeness on the world, you will need to get certified by Worldpay. You cannot go live with your application until our technical team has certified your app and you receive your letter of certification. This process is in place to help us ensure that you are indeed using the APIs correctly and that you are obtaining valid results.

Once you get certified, you will be given certified credentials that will replace the testing credentials you obtained when signing up for your sandbox. It's a simple process that you can learn more about by selecting Get Certified below.

Note: When creating your application, set your developer id to "12345678"
