API Reference Guide for Web Services
The API allows you to securely submit several transaction types by way of your own e-commerce site.

• Your customer can create a profile that includes personal information and billing details. The profile is securely stored, which is used for future e-commerce transactions and can be modified by the customer when required.
• Your customer can transparently process purchases on your e-commerce site – the customer experiences your branded site only.
• You can use existing customer profiles to process purchase transaction requests, e.g., for billing requests that occur regularly.

Direct Payment Component Guide (for Java)
The merchant sends transaction requests (e.g., Purchase) to the transaction processor via Java Direct Payment, which acts as a secure transport medium. The merchant uses sockets through SSL (Secure Sockets Layer) to communicate securely with the payment server over the Internet. Transactions are validated at both the Java Direct Payment and the payment service levels. For example, the transaction processor sends a response for both successful and failed transactions (e.g., if an invalid card type is supplied).

Direct Payment Component Guide (for Windows 2000/NT)
The merchant application (ASP, VB, or VC++) uses a dictionary object to exchange relevant data with the Direct Payment component. The dictionary object is a data structure that stores information in pairs of keys, with a one-to-one key value (e.g., the credit card type might be Visa). This transaction request information is coded in an ASP script or in a VB or VC++ application.

Direct Payment Component Guide (for Unix/Linux)
Transactions are validated at both the Direct Payment library and the payment service levels. For example, the transaction processor sends a response for both successful and failed transactions (e.g., if an invalid card type is supplied). The Direct Payment library sends an error message if information it requires is missing or incorrect (e.g., if your merchantId value is missing).

Payment Notifications
Once a payment has been processed, either through to success or to cancellation, information about that payment is sent to you by using the Payment Response feature. The Payment Response feature posts the payment information from our server to a URL on your server via HTTP(s). This enables you to validate the information, update the order and if required display your own shopper result pages.
