API integration is a solution provided by PaySat Inc. to all merchants that have their own orders database, and desire to keep the order page under their identity.
Paysat offers two solutions that vary according to the environment of the merchant site:  CGI script (platform independent).  Managed .Net DLL, for integration with .Net web projects.
This document illustrate the .Net integration module
.Net API Integration
To use the .Net DLL API, the following steps must be performed:
a. The merchant will download .Net API version from his Paysat Merchant Profile which will contain 3 files (MerchantApiWebService.dll , MerchantAPIClient.dll & MAPIConfig.xml) b. The merchant will include those file in his shopping Cart Web Project and add a reference to them so that he can use the classes included in them. c. Using (MerchAPIClient) class which is included in (MerchantAPIClient) namespace the merchant will create an order object. d. This object will contain the 5 Functions that will be used. SingleOrder AmountOrder RecurringOrder SpecialOrder GetStatus Merchant will pass the required parameters for each Function, this function return a string which will contain the Response to ordering operation.
