POS Application Program Interface Software


Interfacing the Point-Of-Service Device is now easier than ever

POS Application Program Interface  (Xi and XiServer)

What is "Xi and XiServer"

The Retail Choice Xi product is a middleware application that runs on customer point-of-service (POS) systems.  Xi provides POS applications with an interface to Xtran and the Retail Choice Network.

The Xi Server runs as a background process (or Windows service) on the customer’s Point-of-service (POS) system

XiServer:

  • Converts device requests and responses to/from the message format required by Xtran

  • Concentrates requests from multiple (store) devices onto communication links to the Xtran gateway.

  • Returns an Xtran response to the device that originated the request.

  • Manages multiple links to one or more Xtran gateways

  • Round robins or priority (primary/secondary) schedules transaction requests among multiple Xtran connections.

  • Automatically reverses transactions that fail due to network/issuer timing and system problems.

The interface to XiServer is through the Xi Application Programmer’s Interface (API).  The interface is ‘object’ oriented.  The transaction is defined by an ‘Xi Transaction Object’. The POS application accesses the Xi Transaction Object by executing functions in the Xi API.

To execute a transaction the POS application:

  • Creates an Xi Transaction Object (defining the transaction and account type)

  • Defines additional transaction information such as amount and account number

  • Sends the transaction request to XiServer for processing.  Optionally waits for a response.

  • Extracts and processes results from the transaction response.

  • Closes the Xi Transaction Object
