I've done quite a bit CC stuff over the years and every processor does things a bit differently. For example the test environment is always different (some have test card numbers, some have test servers).

But, there are quite a few things in common too (mostly the data they need). Usually there are example scripts (often in Perl) that you can get started quick with too.

I use this scheme:

Site > Sanitiser > CC Processor

Basically, I don't code anything that is CC specific in the site and anything that a CC Processor needs I add to the sanitiser step. The CC Processor step usually ends up being only one subroutine. If I switch processors (which doesn't happen very often) I rewrite the last step and maybe add a few things to the Sanitiser step.

It will never be easy switching CC processors, but I have found that this scheme does make it fairly painless.
