Hello,
I am evaluating BVC for use in a greek eshop and I would like to ask how difficult it is to create a custom (simple) gateway to support the greek gateway Deltapay.

The way it works is this (I've already done that with custom coding for simple websites, not eshops):
I send them a POST with my user/pass, some details for the sum I want to be billed and a transaction ID. The user then enters his credit card details in their site and after the operation is completed he is redirected back to my site, with the transaction result.

Based on that description, can you give me a rough estimate of what coding (and other customizations) needs to be done to integrate such a procedure with BVC? I really need this answer, since this will be one of the two deciding factors for my decision after evaluation.


Thank you in advance,
Vasilis Toulias
