I am working on integration of liqpay payment gateway to site using their available documentation at: https://www.liqpay.ua/en/doc/checkout.
so far I have integrated their checkout method (client-server). user clicks subscribe and it redirect user to liqpay checkout screen. but problem is when user cancel transaction or it is successful user. user just redirect back to given return flag available in their argument list. without any status code or message in url like other payment gateways do.
Need suggestions on it. if someone has experience in working with Liqpay.
