I really hope that you will be able to make a plug for connection payment modules for payment systems
1) ROBOKASSА - one of most popular payment system
API and examples for other CMS modules, the code in the public domain can be taken here
http://robokassa.ru/ru/HowTo.aspx
2)
Webmoney - the most common electronic payment system in Russia and the former CIS countries.. Slightly in Germany.
API here
https://merchant.wmtransfer.com/conf/guide_simple.asp#step1
or
https://merchant.webmoney.ru/conf/default.asp
3) INTERKASSA - site interkassa.com
very popular system, as it involves a large number of possible methods of payment (including below Webmoney), direct payment with Visa and MasterCard cards, payment terminals, and much more.
At the moment the most powerful system.
4) SMS payment - SMScoin.com (payment prices like Fortumo)
--
If necessary I can help with the translation and adaptation of the language.
