Hi there 👋 do you have more details on what you're seeing? It looks like that's a line to create a Payment Intent, do you see the request being made to Stripe at all?

safe yacht Apr 30, 2024, 12:54 PM

#

yes I guess I can see in Logs

#

ID: req_uK1iP39gG5QUNE

#

my app is here as of now: - (void)reader:(nonnull SCPReader *)reader didRequestReaderInput:(SCPReaderInputOptions)inputOptions

#

app showing the swipe card on my UI

#

here user cancels the payment I mean goes back to previous screen

#

then come again and try to make payment

#

but app does not receives any response from [[SCPTerminal shared] createPaymentIntent:params completion:^(SCPPaymentIntent *createResult, NSError *createError) method

unborn flame Apr 30, 2024, 12:57 PM

#

Hm, odd, the request you shared shows that a response is being sent.

safe yacht Apr 30, 2024, 1:00 PM

#

yes for 1st time

unborn flame Apr 30, 2024, 1:00 PM

#

Do you have log lines in success and error functions that get triggered when that function completes? Do you see any of those being hit?

safe yacht Apr 30, 2024, 1:00 PM

#

2nd time nothing

#

just in wating state

unborn flame Apr 30, 2024, 1:00 PM

#

Oh, are you seeing a requset ID being generated for the second time?

safe yacht Apr 30, 2024, 1:00 PM

#

how to check that?

#

request ID?

unborn flame Apr 30, 2024, 1:01 PM

#

You can check your logs in your Stripe dashboard:
https://dashboard.stripe.com/logs?
https://support.stripe.com/questions/finding-the-id-for-an-api-request

safe yacht Apr 30, 2024, 1:02 PM

#

let me try again

#

ID: req_ps2jHeuIND8yRv

#

just created

#

now app is in - (void)reader:(nonnull SCPReader *)reader didRequestReaderInput:(SCPReaderInputOptions)inputOptions

#

waiting for card input

#

Swipe / Insert / Tap

#

now I will cancel and going to previous screen and will try again

#

[[SCPTerminal shared] createPaymentIntent:params completion:^(SCPPaymentIntent *createResult, NSError *createError)
{
if (createError)

now app is waiting for this method

#

to get response

#

this time I dont see new ID on logs

#

unborn flame Apr 30, 2024, 1:07 PM

#

Yeah, I'm not seeing any evidence that a second request is being made by your app. Do you have logging in plave to make sure your app is getting back to the chunk of code that you think it is? Are you seeing any errors in your logs that could indicate why that method isn't running if it is being reached?

safe yacht Apr 30, 2024, 1:09 PM

#

checking

#

I checked, all steps are repeated

#

nothing missing

#

app creates SCPPaymentIntentParameters without error

#

then calling [[SCPTerminal shared] createPaymentIntent:params completion:^(SCPPaymentIntent *createResult, NSError *createError)

#

and just waiting

#

unborn flame Apr 30, 2024, 1:17 PM

#

I don't see any log lines in the failure block there, are you sure it isn't failing and not logging the returned error? (But I'm also not too familiar with iOS dev environments, so I may be misreading something)

safe yacht Apr 30, 2024, 1:21 PM

#

#

this is : SCPPaymentIntentParameters

safe yacht Apr 30, 2024, 1:23 PM

#

unborn flame I don't see any log lines in the failure block there, are you sure it isn't fail...

yes sure each line is getting executed same way like 1st time

#

1st time I am getting response but not 2nd time

#

1st time after creating Payment Intent I cancel the process and again trying to create payment intent

#

and it got stuck

unborn flame Apr 30, 2024, 1:25 PM

#

When you say you cancel the process, what does that mean? Are you canceling the reader action and seeing it leave the screen asking for input?

safe yacht Apr 30, 2024, 1:26 PM

#

no, just remove the payment screen and re open it

unborn flame Apr 30, 2024, 1:28 PM

#

So the reader never leaves the card input screen? If so, I think that may be why nothing is happening.

safe yacht Apr 30, 2024, 1:28 PM

#

reader leaves the card input screen in my app

#

but I dont call any stripe API to notify this

#

more: the reader is in waiting state - (void)reader:(nonnull SCPReader *)reader didRequestReaderInput:(SCPReaderInputOptions)inputOptions

#

to tap card or input card to the reader to capture

#

yoare u understanding?

unborn flame Apr 30, 2024, 1:36 PM

#

Kind of, but I have no idea why you'd be seeing that behavior. I have teammates looking at the thread to see if they can paint a more complete picture of what you're describing for me.

safe yacht Apr 30, 2024, 1:37 PM

#

sure

#

if any iOS dev is there, they can understand this code

unborn flame Apr 30, 2024, 1:38 PM

#

They confirmed what I was suspecting, that you need to actually cancel the terminal SDK action before requesting it take another action.
https://docs.stripe.com/terminal/payments/collect-payment?terminal-sdk-platform=ios#collect-cancel-collection

Collect payments

Prepare your application and backend to collect payments using Stripe Terminal.

safe yacht Apr 30, 2024, 1:40 PM

#

ok let me try

#

do I need to call this when user cancels while reader is in waiting state?

unborn flame Apr 30, 2024, 1:44 PM

#

Yes

safe yacht Apr 30, 2024, 1:47 PM

#

I dont think so because it does not make any difference

unborn flame Apr 30, 2024, 1:50 PM

#

More details?

safe yacht Apr 30, 2024, 1:56 PM

#

I put this code on my cancel button and tried again to pay

#

and same stuck

unborn flame Apr 30, 2024, 1:58 PM

#

What code? What are you seeing? What logging is being triggered? Are you seeing any errors?

safe yacht Apr 30, 2024, 1:58 PM

this URL suggest code

#

that one

unborn flame Apr 30, 2024, 2:01 PM

#

Okay, and you seem to be using an M2, so I'm guessing you're referring to the programatic cancelation shown there rather than the customer initiated approach.

safe yacht Apr 30, 2024, 2:02 PM

#

correct

unborn flame Apr 30, 2024, 2:02 PM

#

That code isn't shown in the doc, so can you share what code you added?

safe yacht Apr 30, 2024, 2:02 PM

#

unborn flame Apr 30, 2024, 2:03 PM

#

I see, you added the customer initiated flow which doesn't work for readers without a screen like the M2

#

You need to cancel the action:
https://stripe.dev/stripe-terminal-ios/docs/Classes/SCPCancelable.html#/c:objc(cs)SCPCancelable(im)cancel:

safe yacht Apr 30, 2024, 2:05 PM

#

ok

#

this will require the current payment intent as well right?

unborn flame Apr 30, 2024, 2:11 PM

#

I don't believe so.

safe yacht Apr 30, 2024, 2:17 PM

#

ok let me try

#

Done !!!

#

thanks for your patience and time !!!

unborn flame Apr 30, 2024, 2:20 PM

#

Any time! Glad we were able to get you there!

safe yacht Apr 30, 2024, 2:20 PM

#

1 more thing

#

just a minor one

#

self.collectCancelable = [[SCPTerminal shared] collectPaymentMethod:createResult completion:^(SCPPaymentIntent *collectResult, NSError *collectError)

during creating payment intent.

cancel click:
[self.collectCancelable cancel:^(NSError * _Nullable error)
{

}];

#

this is my code, is it ok ?

unborn flame Apr 30, 2024, 2:25 PM

#

My teammate isn't seeing anything obvious jumping out at them. Is it functioning as you're expecting in your testing?

safe yacht Apr 30, 2024, 2:26 PM

#

yes
