eFresh Client API

The eFresh Client API component provides an easy way to add eFresh transaction capability to Windows based applications. It handles all security and communications with the eFresh server. It is available as an OCX module.

The client application using the eFresh Client API just needs to pass the API the product information that it needs and the API will connect securely to the eFresh server and retrieve that product.

Simply reference this component from your application and then assign values to the necessary parameters. The component will build a request string, encrypt it, and transmit the data to the eFresh server, as well as receive the encrypted response, which is decrypted and return to the calling application.

The key features of the component include:

connects with eFresh Server accesses security key stored on smart card supports dial up and TCP connections supports server to server connections provides 64 bit encryption supports modified DUKPT key management scheme supports built-in error detection provides fast integration using DLL or OCX component.

The API is provided with a test application and the test application's Visual Basic source code as an example to aid the developer.
