This interface is ideal for websites which have a fully developed shopping cart in place, and just want to have a third-party online transaction verification mechanism.

In this interface, the entire transaction happens on your website; including the display of the final amount payable. The merchant is then required to send a few defined set of values to the ABCPayments.com gateway for online payment verification.

For the purpose of data security, while passing the values, this service requires integration of ABCPayments.com scripts (available in PHP / Perl / ASP) with the merchant's payment interface, and hence requires the merchant to have a bit of hands-on knowledge of any of the software programming language like Perl / PHP / ASP. ABCPayments.com anyhow provides extensive online as well as offline support to the merchant to make the things running.
