Client app paytm webflow not working correct.

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
}

} }
