In which controller is payment processing in opencart?

Question

opencart

I have a opencart opencart lickplay module, and it's kind of crooked and doesn't change its status after paying for the order.
After a person has paid, he is redirected to the "order successfully created" page.
What controllers work at the moment of redirection from the likpay to the site, except for the likpay itself?
I hope I explained clearly

Answer 1

Did you set the order statuses in the LIQPAY settings?
See if extension/payment/liqpay/callback comes after payment, it is this method that should change the status of the order in case of successful payment
