An Application Programmers Interface (API) is an interface that permits external (remote) software applications to programmatically call functionality within another software (host) application. Specifically, the remote application only needs to be aware of the API's functionality and not that of the hosting application to accomplish a task.

Example:

Request for a Credit Card Approval

Remote POS application collects essential data (card number, expiration date, transaction amount, etc.) then sends a Credit Card Approval request to the API. The API processes the data and returns the Approval Code to the remote application.

The remote application only needs basic information to process a transaction. It does not need to know whether a modem is available, what number to dial, what protocol to use, or how to format the data for the transaction processor.

Automate the Payment Process

With the POS-partner API, you can automate all of your credit card authorization and settlement transaction processing, while improving efficiency and reducing backoffice costs.

Open Architecture

XML (Extensible Markup Language) is used as the API messaging format for the POS-partner API, due to its open architecture and nonproprietary nature. Its open message format permits integration with any host capable of creating an XML message.

Additional information regarding XML may be found at the following Web Sites.
