@tepid peak Hello! I'm happy to help but I'm going to need a lot more specific details than what you said unfortunately.
Step 1: Exact PaymentIntent id
Step 2: Exact iOS client-side code and the exact doc URL you are following
Step 3: Exact error you get, clear logs about where the issue is failing, etc

The exact error i am getting is "Payment Failed"

light phoenix Oct 9, 2023, 5:45 PM

#

That I'm sorry I didn't expect you to drop dozens of lines of code like this

tepid peak Oct 9, 2023, 5:46 PM

#

Oh i apologise

#

I will try to explain better

#

https://www.youtube.com/watch?v=QcM9DGcJSjs&list=PLy1nL-pvL2M6yD1D72ceqqrW_1BqyN4It&index=6

#

This is what i am following

#

My code is identical to this

@lofty frigate is taking over for me and will help

lofty frigate Oct 9, 2023, 5:47 PM

#

Hello! I'm taking over and catching up...

tepid peak Oct 9, 2023, 5:47 PM

#

Hi Rubeus!

#

My console and stripe dashboard looks like it should be working, however, when I try to make a test payment (in this case $1), I am getting an error from apple pay saying that the payment failed

lofty frigate Oct 9, 2023, 5:48 PM

#

What's the underlying error logged in the debugger when this happens?

tepid peak Oct 9, 2023, 5:49 PM

#

#

other than that the payment intent is showing that it was created successfully

lofty frigate Oct 9, 2023, 5:50 PM

#

The Payment Intent creation is separate from the Apple Pay payment attempt. I'm asking what errors are showing up in Xcode when this happens?

tepid peak Oct 9, 2023, 5:51 PM

#

There arn't any, that is what i'm confused about

lofty frigate Oct 9, 2023, 5:51 PM

#

Can you share a screenshot or video of what you're seeing?

lofty frigate Oct 9, 2023, 5:52 PM

#

No, sorry. Earlier you said this:

my apple pay gets rejected and says payment failed

Where are you seeing that? Can you share a screenshot of that?

tepid peak Oct 9, 2023, 5:53 PM

#

Its not in Xcode. Its on my physical device when I try to make a payment. I choose a card to pay with, click pay on the apple pay popup, and then it loads for a second and gets rejected, And then the applePayModel.paymentStatus = case .error:

lofty frigate Oct 9, 2023, 5:54 PM

#

Can you run the app on your device from Xcode so you can see the debugging console when this error happens?

tepid peak Oct 9, 2023, 5:55 PM

#

The screenshot I provided is what I receive when this happens

lofty frigate Oct 9, 2023, 5:55 PM

#

Meaning in Xcode choose your physical device as the target, then run from Xcode, then reproduce the error, then look in Xcode's debug console?

tepid peak Oct 9, 2023, 5:56 PM

#

that is what i provided. this is why i am confused because the console hasn't trown an error and stripe hasn't either. The only way i can see an error is on my physical device.

Is there something specific you want me to print out, like write a print statement and then recreate the error?

lofty frigate Oct 9, 2023, 5:57 PM

#

To clarify, is your code above displaying the error? Meaning is Text("Payment failed!") the source of the error you're seeing?

tepid peak Oct 9, 2023, 5:57 PM

#

wait

#

Yes

#

When this happens the Text box is showing on my device Payment Failed

lofty frigate Oct 9, 2023, 5:58 PM

#

With or without the !?

tepid peak Oct 9, 2023, 5:58 PM

#

with

lofty frigate Oct 9, 2023, 5:58 PM

#

Can you add additional logging to your code to surface the underlying error details?

tepid peak Oct 9, 2023, 5:59 PM

#

yes i can

#

what exactly would you like to see

#

because after the payment is ran, and gets failed, this block of code switchs the error case and displays the Text("Payment Failed!") with the image:

if let paymentStatus = applePayModel.paymentStatus {
HStack {
switch paymentStatus {
case .success:
Image(systemName: "checkmark.circle.fill").foregroundColor(.green)
Text("Payment complete!")
case .error:
Image(systemName: "xmark.octagon.fill").foregroundColor(.red)
Text("Payment failed!")
case .userCancellation:
Image(systemName: "xmark.octagon.fill").foregroundColor(.orange)
Text("Payment canceled.")
@unknown default:
Text("Unknown status")
}
}
}

lofty frigate Oct 9, 2023, 6:01 PM

#

Go into your ApplePayModel class and add logging in your didCompleteWith delegate method. There should be an error object passed in there that contains additional details.

Apple Pay Error: There was an unexpected error -- try again in a few seconds

lofty frigate Oct 9, 2023, 6:02 PM

#

Where is that from? It's doubtful that's related.

#

Errors with the m.stripe.com domain should not impact functionality.

#

Where is Apple Pay Error: There was an unexpected error -- try again in a few seconds from?

tepid peak Oct 9, 2023, 6:03 PM

okay, sorry.

I am adding the didCompleteWith error, give me a few moments

lofty frigate Oct 9, 2023, 6:05 PM

#

Usually that error indicates an unexpected response from Stripe, like a 500, or unparsable JSON. It's very unusual to encounter that one, as those things mostly never happen. Is the device you're testing with able to access the internet without restrictions? Also wondering if the date and time on the device is set correctly?

tepid peak Oct 9, 2023, 6:06 PM

#

Yes it is, as it is my personal device. Would you like me to try again on another physical device?

lofty frigate Oct 9, 2023, 6:06 PM

#

If you have another device there yeah, that would be helpful.

tepid peak Oct 9, 2023, 6:06 PM

#

lofty frigate Oct 9, 2023, 6:07 PM

again, an issue with another device

lofty frigate Oct 9, 2023, 6:08 PM

#

Did you run into any issues creating your Apple merchant ID or certificate?

tepid peak Oct 9, 2023, 6:09 PM

#

I did everything according to the stripe docs

lofty frigate Oct 9, 2023, 6:09 PM

#

Like any issues with these steps? https://stripe.com/docs/apple-pay?platform=ios#accept

tepid peak Oct 9, 2023, 6:11 PM

#

Question, if my merchant ID is in red text on the Apple Pay of the Signing & Capabilities, would that persent an issue?

#

yesterday it was white

lofty frigate Oct 9, 2023, 6:12 PM

#

Ah, yes, that indicates there's some kind of issue there.

tepid peak Oct 9, 2023, 6:12 PM

#

My developer account is currently being migrated right now, would that impact this?

lofty frigate Oct 9, 2023, 6:12 PM

#

That could cause the issue you're seeing.

#

Honestly I'm not sure.

#

Probably.

#

When you present the Apple Pay sheet the app reaches out to Apple to try and create an Apple Pay Session using your merchant ID and certificate.

#

If your account is in a wonky state that's probably failing and causing this error.

tepid peak Oct 9, 2023, 6:13 PM

#

My certificate should be fine though as i submitted the stripe one to my dev account, and then reuploaded the response certificate back to stripe

lofty frigate Oct 9, 2023, 6:14 PM

#

One way to confirm this would be to use a third-party network debug tool to see what's going on with the underlying HTTP requests and responses: https://developer.apple.com/documentation/network/taking_advantage_of_third-party_network_debugging_tools

#

My guess is the request to create the Apple Pay Session is failing with an unexpected error/response due to your account state.

tepid peak Oct 9, 2023, 6:14 PM

#

Okay, i will look into it. Regarding my code, if you don't see an issue with my code, then i can probably figure this out myself! Thank you for your help Rubeus!

lofty frigate Oct 9, 2023, 6:14 PM

#

Yeah, I recommend the network/HTTP debugging as the next step.

tepid peak Oct 9, 2023, 6:14 PM

#

Okay Great, i will do that right now

lofty frigate Oct 9, 2023, 6:14 PM

#

That should shed some light on what's actually going on.

tepid peak Oct 9, 2023, 6:15 PM

#

Okay, I will reach out again if I need your help!
