Olvio.Ecommerce is a payment processing class library for the Authorize.Net payment gateway. It includes all the latest features, SIM and AIM integration methods, CC and ECHECK processing, hash validation, response stream reader and more. Includes a SimResponseReader class to handle the silent posting from a SIM transaction. It can validate and process transactions for the Wells Fargo merchants. Fully written in C# it offers a strong object model with powerful exception handling that allows the merchant to validate data before sending it to the gateway. The class library automatically reads and parses the gateway response and validates the MD5 hash to assure that the response is authentic. Includes also a SNTP class that is able to connect to an internet time server and get the real time for a certain zone to be used in connection with the SIM integration method.
