How can i integrate razorpay payment gateway without using cordova in ionic 4

I am supposed to integrate a payment gateway in ionic4 pwa by client. But according to my company i am restricted to use cordova because after adding it, the company’s built basic app routing starts misbehaving. so I can’t use cordova.
so, please help me in adding razorpay checkout without cordova. or suggest me any alternative of cordova.
