hey

can you help me?

Hi, I am searching for resources

#

Have you checked this video? https://www.youtube.com/watch?v=NOceh42ZNEY

#

Is that what you are referring to?

night dove Oct 6, 2021, 8:01 AM

#

I haven't watched this video

#

oh，Thank you

night dove Oct 6, 2021, 8:24 AM

#

I checked this video and I found that the 3DSv2 verification UI is not evoked in this video

#

I use STPPaymentOptionsViewController for 3DSv2 verification

#

But I don’t know how to evoke the 3DSv2 verification UI

#

you have to confirm a PaymentIntent

#

STPPaymentOptionsViewController is just to pick a PaymentMethod, it doesn't process a payment so it doesn't do anything with 3D Secure

#

the idea usually is in your paymentOptionsViewControllerDidFinish delegate you create and confirm a SetupIntent to set up the card (which might run 3D Secure), or create and confirm a PaymentIntent to process a payment.

#

func paymentOptionsViewControllerDidFinish(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
         print("didFinish");
        
        if let card = selectedPaymentOption as? STPPaymentMethod {
            self.customerContext?.retrieveCustomer({ (customer, error) in
                guard let customer = customer else {
                    print(error!)
                    return
                }
                MyAPIClient.sharedClient.createSetupIntent(customerId: customer.stripeID) { (setupIntentClientSecret, error) in
                guard let clientSecret = setupIntentClientSecret, error == nil else {
                    print("Error contacting backend(create)")
                    return
                }
                let setupIntentParams = STPSetupIntentConfirmParams(clientSecret: clientSecret)
                setupIntentParams.paymentMethodID = card.stripeId
                    STPPaymentHandler.shared().confirmSetupIntent(setupIntentParams, with: self, completion: { (status, setupIntent, error) in
                    ...
                    ...
                  ...

lofty rover you have to confirm a PaymentIntent

I tested it, this is a normal payment process, but it will not evoke the UI of the 3DSv2 process

lofty rover Oct 6, 2021, 9:29 AM

#

it should if you use a card that supports it

#

https://stripe.com/docs/testing#three-ds-cards

#

did you try 4000000000003220 ?

and what happened exactly? can you share the code you used?

#

and an example PaymentIntent pi_xxx you tested with

lofty rover and what happened exactly? can you share the code you used?

#

This is my code

#

Hold on

lofty rover and what happened exactly? can you share the code you used?

📎 PleaseOrderVC.m

#

this my code

lofty rover Oct 6, 2021, 10:09 AM

#

I don't really read objective-c, but do you implement the STPAuthenticationContext protocol?

#

also , what happened exactly when you run this code?

night dove Oct 6, 2021, 10:10 AM

#

Yes, it implements require Method

lofty rover Oct 6, 2021, 10:10 AM

#

does it popup a UI, does it does crash, are there errors in the logs, is the completion function called and what's the status returned if so?

night dove Oct 6, 2021, 10:11 AM

#

has present STPPaymentOptionsViewController

#

But it doesn't evoke 3dSV2-related UI

#

paymentHandler confirmPayment:withAuthenticationContext: completion：

#

always return STPPaymentHandlerActionStatusFailed

lofty rover Oct 6, 2021, 10:16 AM

#

does it work for cards like 4000000000003063 that use 3DSv1 instead of v2?

#

if so and it's only broken for v2 , then you probably haven't installed the library correctly somehow and you're missing the Stripe3DS2.xcframework part of it, perhaps, since that's what creates the native 3DSv2 interface https://github.com/stripe/stripe-ios#releases

night dove Oct 6, 2021, 10:24 AM

#

I just tested it 4000000000003063

lofty rover Oct 6, 2021, 10:24 AM

#

and?

night dove Oct 6, 2021, 10:24 AM

#

Also return STPPaymentHandlerActionStatusFailed

#

How should achieve STPPaymentOptionsViewController 3 dsv2 pay

#

process

#

😢

lofty rover Oct 6, 2021, 10:32 AM

#

the code you have seems like mostly the right approach really

#

what's in the NSError *error ?

#

like dump it out and see what the specific error that's happening is

night dove Oct 6, 2021, 11:34 AM

#

lofty rover the code you have seems like mostly the right approach really

lofty rover Oct 6, 2021, 11:35 AM

#

what's the question?

#

my code is different than yours yes(it uses Swift and I use a SetupIntent, you use Obj-C and a PaymentIntent) but it shouldn't be related, it's just different ways to use the API and should be separate from this 3D Secure issue.

#

what's in the NSError *error in the completion block when you get back the STPPaymentHandlerActionStatusFailed status? That's the next step, inspect that error to see what's happening and why it fails, and I can try to go from there in helping you! (also you never shared an example pi_xxx ID like I asked for, that would help too).

lofty rover what's the question?

why?

lofty rover Oct 6, 2021, 11:52 AM

#

why what? Sorry, it's hard to answer one-word questions.

I can try to help you!
can you share an example PaymentIntent pi_xxx you tested with?
what is the contents of the NSError's userInfo dictionary?

night dove Oct 6, 2021, 11:53 AM

#

Wait a moment

lofty rover Oct 6, 2021, 11:54 AM

#

night dove Yes, it implements require Method

also you said this but I don't see authenticationPresentingViewController being implemented anywhere in the code you shared

lofty rover Oct 6, 2021, 11:57 AM

#

ok so that error seems clear

#

whatever [NCStripePaySupportTool sharedTool].client_secret is in the code you shared earlier, it's null. Does that make sense?

#

also you must not be using that code you shared anymore, right? Since this error talks about a SetupIntent , so you must be calling confirmSetup now instead, right?

night dove Oct 6, 2021, 12:00 PM

#

lofty rover also you said this but I don't see `authenticationPresentingViewController` bein...

I only implemented this method

lofty rover Oct 6, 2021, 12:01 PM

#

ok, let's ignore that for now then

night dove Oct 6, 2021, 12:01 PM

#

lofty rover Oct 6, 2021, 12:01 PM

#

yep but you need to implement it, like

# pragma mark STPAuthenticationContext
- (UIViewController *)authenticationPresentingViewController {
    return self;
}

in your .m file

#

but putting that aside, do you understand the point I made above? about your client_secret being null?

night dove Oct 6, 2021, 12:03 PM

#

#

Wait a moment

lofty rover Oct 6, 2021, 12:07 PM

#

yep so the error message you shared is quite clear I think, right?
whatever [NCStripePaySupportTool sharedTool].client_secret is in that code, it's null.
that's why you get an error No such setupintent: '(null)', .

night dove Oct 6, 2021, 12:08 PM

#

https://stripe.com/docs/mobile/ios/basic

#

Should I implement this Integration?

lofty rover Oct 6, 2021, 12:12 PM

#

I mean that is what you're doing right?

night dove Oct 6, 2021, 12:12 PM

#

Of course,

lofty rover Oct 6, 2021, 12:13 PM

#

ok! So I don't understand the question. If that's what you want to use, you can.

#

but overall why not just start from the first page of our docs (https://stripe.com/docs/payments/accept-a-payment?platform=ios) and build that (the PaymentSheet integration) if you're starting something from scratch? It's probably easier.

night dove Oct 6, 2021, 12:14 PM

#

you look

#

lofty rover Oct 6, 2021, 12:14 PM

#

yep that's a PaymentIntent ID which is wrong.

night dove Oct 6, 2021, 12:14 PM

#

the client_secret nonull

lofty rover Oct 6, 2021, 12:14 PM

#

because you're calling confirmSetupIntent, so you need to create a SetupIntent on your backend instead of a PaymentIntent

#

you were using PaymentIntents when we started this conversation but you changed the frontend to SetupIntents at some point it seems!

#

so if that's what you want to use then you need to change your backend server to create and return a SetupIntent (will look like seti_xxx_secret_yyy) instead.

night dove Oct 6, 2021, 12:22 PM

#

I did it a different way

#

STPPaymentHandlerActionStatusFailed

lofty rover Oct 6, 2021, 12:28 PM

#

yep so

authenticationPresentingViewController is not in the window hierarchy. You should probably return the top-most view controller instead.,
is the error message.

#

so it's to do with your authenticationPresentingViewController — the VC you're using here is not the top-level one. Hard for me to help since I don't know how your app's view hierarchy is set up exactly.

night dove Oct 6, 2021, 12:30 PM

#

oh, thanks

#

I try again

#

#

STPPaymentOptionsViewController

#

should use a push or present show STPPaymentOptionsViewController?

night dove Oct 6, 2021, 12:44 PM

#

lofty rover yep so > authenticationPresentingViewController is not in the window hierarchy....

this

#

Error Domain=STPPaymentHandlerErrorDomain Code=7 "There was an unexpected error -- try again in a few seconds" UserInfo={com.stripe.lib:ErrorMessageKey=authenticationPresentingViewController is already presenting. You should probably dismiss the presented view controller in prepareAuthenticationContextForPresentation., NSLocalizedDescription=There was an unexpected error -- try again in a few seconds}

lofty rover Oct 6, 2021, 12:51 PM

#

this usually means you're calling confirmPayment twice basically, for example your code calls it again before it completes.

night dove Oct 6, 2021, 12:56 PM

#

Should I implement <STPAuthenticationContext> Protocol Other Method?

lofty rover Oct 6, 2021, 12:58 PM

#

no, the only one you have to complement is authenticationPresentingViewController() .
