iOS "Link" payment method not working

[Albertbol]

Describe the bug
When you choose Link payment method in mobile payment sheet, link in app browser requests information you write it there than it automatically closes, but now payment sheet does nothing you can again choose payment type it does not do anything. When i work locally in test mode it works, on android it started to work in prod when i removed android:taskAffinity="" in AndroidManifest.xml.
When i check transaction in Stripe Dashboard it says:
A request to create a PaymentIntent completed ->The PaymentIntent requires a payment method (requires_payment_method)

So what does it mean is it a bug on your side that payment method is not sent or what is happening and why only prod ios not working.

I have followed schemas docs, added return URL custom flow is set to false. Payment methods are set to automatic. Worth to mention that in my payments i use onBehalfOf to pay to connected accounts. Every other method works apple and cards.

Info.plist

<dict>
	<key>CFBundleTypeRole</key>
	<string>Editor</string>
	<key>CFBundleURLName</key>
	<string>safepay</string>
	<key>CFBundleURLSchemes</key>
	<array>
		<string>myappname</string>
	</array>
</dict>

init payment dart file:

await Stripe.instance.initPaymentSheet(
      paymentSheetParameters: SetupPaymentSheetParameters(
        customFlow: false,
        merchantDisplayName: 'myappname',
        paymentIntentClientSecret: paymentIntentClientSecret,
        returnURL: 'myappname://stripe-redirect',
        customerId: customer, (customer id)
        applePay: const PaymentSheetApplePay(
          merchantCountryCode: 'LV',
        ),
        googlePay: const PaymentSheetGooglePay(
          merchantCountryCode: 'LV',
          testEnv: true,
        ),
        style: ThemeMode.dark,
      ),
    );

server ts:

const paymentIntentCreateParams: Stripe.PaymentIntentCreateParams = {
          amount,
          currency,
          customer: customer.id,
          metadata,
          automatic_payment_methods: {
            enabled: true,
          },
          on_behalf_of: onBehalfOf,
          transfer_data: {
            destination: onBehalfOf,
          },
          application_fee_amount: fixedFeeInCents,
          capture_method: 'manual',
        };
        const paymentIntent = await this.stripe.paymentIntents.create(
          paymentIntentCreateParams
        );
        paymentIntentClientSecret = paymentIntent.client_secret;
        ephemeralKey = await this.stripe.ephemeralKeys.create(
          { customer: customer.id },
          { apiVersion: '2025-03-31.basil' }
        );
        paymentIntentId = paymentIntent.id;

Any ideas whats wrong?

To Reproduce
Not sure how to reproduce as it does not work in production only, and yes i have enabled Link in dashboard everything is on there in settings for all components, i have verified domain.
Expected behavior
Mobile payment sheet should procceed with payment.

Smartphone / tablet

• Device: [e.g. iPhone X] any iphone
• OS: [e.g. iOS 13, Android 10]
• Package version: [e.g. 1.0.0]
• Flutter version [e.g. 2.0.0.] 3.29.3

Additional context
Add any other context about the problem here.

[remonh87]

can you try it with adding to the info.plist?

<key>FlutterDeepLinkingEnabled</key>
	<true/>

[Albertbol]

Thanks for the proposal @remonh87,
But I am using stable version so this suggestion is not relevant:
https://docs.flutter.dev/cookbook/navigation/set-up-universal-links#adjust-ios-build-settings

Version note
If you use a Flutter version earlier than 3.27, you need to manually opt in to deep linking by adding the key and value pair FlutterDeepLinkingEnabled and YES to info.Plist.

Also, it wouldn't work in the test, would it, if the links are broken?

--
Also checked code after reading and i have it explicitly enabled in info plist actually so its there.

@remonh87 any update on this? pretty crucial we have a lot of customers that prefer this payment method :(

[remonh87]

it is hard for me to reproduce as I do not have currently a stripe integration in production where I can try it :( . Also we have no control over the paymentsheet. I saw this before in the past and I think it has to do with Flutter's deeplink mechanism. Did you check that the gorouter deeplink is retrieved?

I think the payment intent is successfully completed so as workaround what you can do is the following:

1. Stripe callback comes in and in the router and you redirect to the screen verifying payment.
2. In this screen you verify with your backend that the payment is success
3. Continue

It looks like this is something that should be handled by Flutter Stripe, isn't it? Otherwise, what's the point? Link is their native payment solution, which should work out of the box. You can create a simple project, connect it to a real Stripe account, and make a payment—it won't go through, but if it does, you can refund it.

I don't use Go Router, I use Auto Router, but I will try to check it and get back to you. It's weird that it works in test but not in production. The test also opens a browser link and comes back, so I don't think it's a deep linking issue.

[remonh87]

you are right the thing is this won't be an easy fix as it is in either in:

• flutter's deeplinking handling
• something in the stripe internal libraries

this will take quite a while to triage so that is why I provide a work around for now

Hi, Any news on this? @remonh87
