Ok so after the miserable results with Audi e-Pay and NetCommerce (terrible policies and services), we decided to go for another alternative to provide a payment gateway. As you all know, PayPal is not available for Lebanese users so that is not an option. We're currently left with either Google Checkout and/or MoneyBookers (but we'll start with only one for now).
The Merchant account will be based in UK so there shouldn't be any problem accepting payments. The problem is what and how to integrate into the website. I went through some of the options provided by Google Checkout, I'm not really sure what to choose. They offer the Buy Now option which is merely an automatically generated HTML snippet that you're supposed to place beside the item you wish to sell. But, we're not really using the gateway to sell items, it will only be used to "buy credits" in order to fill your e-wallet on the site. So basically, you only have to use the payment gateway when you wish to deposit money into your account on the site which will be converted to credits on the site. From then on, you'll be using credits to buy/sell stuff on the site.
The question: What option do you think I should go for? Google Checkout or MoneyBookers? And which specific API do you think I should be using?
