Hello,
i want to create a new payment method which i need but i don't know how. The only guide from my payment platform is this link www.przelewy24.pl/files/cms/13/przelewy24_specification.pdf The payment gateway is Przelewy24 from Poland. I didn't find any payment method for this gateway.
Any help is apreciated.

Thanks in advance.

Hi,
If you need a payment/shipping plugin development,finding a third party developer in order to help you can be a good solution, I would recommend to find a developer via our commercial jobs forum, joomlancers.com or resources.joomla.org
Also, note that if you can develop it yourself, checking the developer documentation will help you : www.hikashop.com/support/documentation/6...ntation.html#payment
