Payment Merchants with easy IPN

Question

Hello, I am looking to integrate to my website many payment merchants. Now I have integrated PayPal and CCBill because they have easy to use IPN.

I want to send to the merchant data like: amount,1custom variable and the merchant should send to my IPN url the amount and the custom variable.

It would be nice if you can give me some names and links to their IPN documentation

Thanks!

Every other payment gateway has some sort of IPN mechanism. It should not be the key factor when you choose a payment processor. The key factor is the percentage of your target audience that the gateway can process. For example, if half of your audience prefers paying with their bank account, you should find a gateway that can do that. And do that well.
