SIM integration using servlet - problem in hiding merchant id and transaction key

[joyanta55]

Hello everyone,

I just tried the "Server Integration Method" provided by the Authorized.net.My Problem is that,all we need is to hide the api key and the treansaction key from others.But while sending "Get" and "Post" request to the "https://secure.authorize.net/gateway/transact.dll" ,the api key and the transaction key need to be sent as the "Get/Post" variable,so anyone can find out those two variables easily.I am doing code on jsp,can anyone provide any suggestion as early as possible??

SIM use the Transaction Fingerprint and don't need the transaction key to be send, and it is a html form post

are you sure you are not using AIM?

on asp.net, we could use a dll to "hide" the id and key, not sure if you can do that with java.
