Client app paytm webflow not working correct.

[IrfanKhatik]

Preconditions:
1] Paytm App not installed on device.
2] Not providing any callback url.

Usecase:
1] Fetch transaction token from backend and startPaytmPayment()
2] APIHandler's openPaymentWebVC() invoked and presented from MyPaytmViewController
3] Paytm web view loaded on presented vc.
4] Payment done by user successfully and weird success transaction html response shown by Paytm. (Screenshot) There is no back button, so user only option have to pull-down to dismiss
5] If user pull-down shown web view vc from Paytm
6] APIHandler's didFinish() api invoked from Paytm with "cancel" AIPaymentStatus.

Problem:
It should be success AIPaymentStatus and valid response provided in didFinish() as payment done by user. Please test from QA all use cases.

Codesnippet:
1.
class MyPaytmViewController: UIViewController {
private func startPaytmPayment() {
appInvoke.openPaytm(merchantId: merchantId,
orderId: orderId,
txnToken: transactionToken,
amount: transactionAmount,
callbackUrl: nil,
delegate: self,
environment: paymentEnvironment,
urlScheme: "paytm(AppConfig.domain)(AppConfig.storeId)")
}
}

extension MyPaytmViewController: AIDelegate {

func openPaymentWebVC(_ controller: UIViewController?) {
    //
    if let vc = controller {
        DispatchQueue.main.async { [weak self] in
            guard let strongSelf = self else { return }
            strongSelf.present(vc, animated: false, completion: nil)
        }
    }
    
    func didFinish(with status: AIPaymentStatus, response: [String : Any]) {
    //
    switch status {
    case .success:
        // Sending response to backend for validation
        validateTransaction(status: status, response: response) 
        break
    case .failed:
        print("Failed")
        break
    case .pending:
        print("Pending")
        break
    case .cancel:
        print("Cancelled")
        break
    default:
        print("Paytm unknown payment status")
        break
    }
}

}
