ios – Why I’m not getting stripe fee success standing? in Swift

To finish stripe fee i’ve two APIs from backend 1)request-payment 2) save-payment

when i click on payButton i’m calling request-payment API and in its success response getting intent information right here i’m amassing paymentIntentId and i’m presenting stripe view controller… after including card particulars in accomplished technique calling save-payment API with paymentMethod.stripeId and paymentIntentId however my fee shouldn’t be success why?

code: with this code fee intent is created efficiently however standing shouldn’t be success its displaying requires_payment_method

import UIKit
import Stripe
class NewBuyRequestPaymentVC: UIViewController, STPAddCardViewControllerDelegate{

@IBAction func payButton(_ sender: UIButton) {
    
    let param: [String: Any] = [
        "description": descriptionTextField.text ?? "No description",
        "amount": amountTextField.text ?? "0.0",
        "enquiry_id": enqrId ?? "",
    ]
    
    APIReqeustManager.sharedInstance.serviceCall(param: param, technique: .submit, url: CommonUrl.request_payment){ [weak self] (resp) in
        
        self?.makePayment = PaymentNewBuyModel(dictionary: resp.dict as NSDictionary? ?? NSDictionary())
        
        self?.paymentIntentClientSecret = self?.makePayment?.outcome?.intent?.client_secret
        paymentIntentId = makePayment?.outcome?.intent?.id
        
        //right here i'm presenting stripe viewcontoller with card
        let config = STPPaymentConfiguration.shared
        config.requiredBillingAddressFields = .none
        let viewController = STPAddCardViewController(configuration: config, theme: STPTheme.defaultTheme)
        viewController.delegate = self
        let navigationController = UINavigationController(rootViewController: viewController)
        self?.current(navigationController, animated: true, completion: nil)
    }
}

func addCardViewControllerDidCancel(_ addCardViewController: STPAddCardViewController) {
    dismiss(animated: true, completion: nil)}

@objc
func addCardViewController(_ addCardViewController: STPAddCardViewController, didCreatePaymentMethod paymentMethod: STPPaymentMethod, completion: @escaping STPErrorBlock) {
    paymentMethodId = paymentMethod.stripeId
    print("fee technique id (paymentMethodId ?? "")")
    savePaymentServiceCall()
    dismiss(animated: true, completion: nil)
}

func savePaymentServiceCall(){
    
    print("fee transaction and technique id (String(describing: paymentIntentId)), (String(describing: paymentMethodId))")
    
    let param = ["term_id" : makePayment?.result?.term_id?.description ?? "",
                 "payment_method" : paymentMethodId ?? "",
                 "intent_id" : paymentIntentId ?? ""
    ] as [String : Any]
    APIReqeustManager.sharedInstance.serviceCall(param: param as [String : Any], technique: .submit, url: CommonUrl.save_payment) { [weak self] (resp) in
        
    }
}
}
