Hi!

I'm trying to implement the 3DS for a saved payment card on SwiftUI. To help you understand what I'm trying to do, I was able to do that in Android using:

======
...
paymentLauncher = PaymentLauncher.create(activity = this, publishableKey = userHandler.settings.paymentPublishableKey!!, stripeAccountId = null) { result ->
handlePaymentResult(result)
}
...
val params = ConfirmPaymentIntentParams.createWithPaymentMethodId(
paymentMethodId = storedPmId,
clientSecret = clientSecret
)

paymentLauncher.confirm(params)

======

#

Now, I'm trying to do that in SwiftUI, here's what I'm doing:

====
On my view:
.paymentConfirmationSheet(isConfirmingPayment: $showPayment, paymentIntentParams: create3DSPaymentParams(), onCompletion: { (paymentHandlerActionStatus, paymentIntent, error) in
Log("Finished Payment: (String(describing: error?.localizedDescription))")
})

private func create3DSPaymentParams() -> STPPaymentIntentConfirmParams {
if let secret = payment3dsAuth?.action?.ClientSecret,
let storedPaymentMethodId = payment3dsAuth?.storedPaymentMethodId {

    Log("secret: \(secret)")
    Log("storedPaymentMethodId: \(storedPaymentMethodId)")
    
    let intent = STPPaymentIntentConfirmParams(clientSecret: secret)
    intent.paymentMethodId = storedPaymentMethodId
    
    return intent
}
else {
    Log("Error!!")
    return STPPaymentIntentConfirmParams(clientSecret: "")
}

}

This payment3dsAuth object is my object for parsing the information from the backend call.

This is the logs that I'm getting, the popup is not shown at all:

OrderConfirmationView.body: Finished Payment: Optional("There was an unexpected error -- try again in a few seconds")

I'm pretty sure that I'm doing something wrong, could you help me?

Sorry for the long text, I'm trying to give as much context as possible

👋 Hi there, just taking a look now

midnight kernel Jan 14, 2026, 1:20 PM

#

thanks!

Hmm, I'm not seeing anything obvious wrong, but this might take a while to dig into properly, so it would probably better if you sent this in to my team so we can take a proper look. You can do so at https://support.stripe.com/contact/email?topic=api_integration

midnight kernel Jan 14, 2026, 1:28 PM

#

do you need more information or what I sent is enough?

If you can find any relevant request IDs (req_xxx) related to your attempts, this might also help https://support.stripe.com/questions/finding-the-id-for-an-api-request

#

ok, I'll try to find that, thanks!

midnight kernel Jan 14, 2026, 1:50 PM

#

am I using the correct objects?

#

I was in doubt because in Android it's called PaymentLauncher and in iOS I only use the paymentConfirmationSheet modifier

#

so, shouldn't I be using a payment sheet or something like that?

Hey there, are you following the guide to enable saved payment methods via customer session in the mobile payment element, or another guide you can point me to?
eg: https://docs.stripe.com/payments/mobile/accept-payment-embedded?platform=ios&type=payment&ui-framework=swiftui#enable-saved-cards

#

When you say "implement the 3DS for a saved payment card" do you mean request 3ds for extra authentication, or are you trying to handle 3ds when prompted for it by the issuer?
