      MidtransMerchantClient.shared().requestTransacation(withCurrentToken: token) { (response, error) in
          if (response != nil) {
              self.openMidtransPayment(viewController: viewController, response: response!)
          } else {
             print("ERROR: \(error)")
          }
      }
  }

  fileprivate func openMidtransPayment(viewController: BaseViewController,
                                       response: MidtransTransactionTokenResponse) {
      if let controller = MidtransUIPaymentViewController.init(token: response) {
          controller.paymentDelegate = self
          viewController.navigationController?.present(controller, animated: true, completion: nil)
      }
  }
