Hello.You can do this with a third-party service.

Hello Aleksej ,

Thanks for your reply. Yes i know this, but i don't want to use Paypal. I want to entegrate my virtual pos to the system. And i don't know how i can do this.

Thanks 

Then you can try custom code.But here you need programming knowledge.

I tried custom code. Before i put my project online, the code was working. But when i put the project online, the code does not work. I got generic error. 

What do you think that the custom code does not work online ? 

Unfortunately, I do not program.And here we need programming skills.
