Just copying your second message here:

The output for most cards come out fine - but for an Interac card has missing fields. Here are 2 transactions I ran with an Interac Debit Card:


Result:  {"amount": 206, "brand": null, "cardholderName": null, "chargeId": "ch_3K9y89Fk5BSitd8b0hUQ6l0V", "clientSecret": "pi_3K9y89Fk5BSitd8b0QomLEtC_secret_ee0PO83rNpp0AIMhD056hJYsG", "country": null, "created": "2021-12-23T15:43:17GMT-05:00", "currency": "CAD", "customerId": null, "fingerprint": null, "funding": null, "generatedCardId": null, "lastFour": null, "readMethod": null, "stripeId": "pi_3K9y89Fk5BSitd8b0QomLEtC"}```


Any clues to why that's happening? The dashboard seems to pick them up just fine

#

Catching up, one sec...

#

Awesome! Thanks - I hit the 2000 character limit lol

kindred vector Dec 23, 2021, 9:42 PM

#

What are the missing fields?

glad stag Dec 23, 2021, 9:42 PM

#

so brand, funding, lastFour, cardHolderName are the main ones I need

#

and they come out as null

#

they're fine for the non-Interac cards

kindred vector Dec 23, 2021, 9:50 PM

#

Interesting. It looks like most of those fields are being set if the data is present

glad stag Dec 23, 2021, 9:50 PM

#

Yeah and it all goes through fine from what I can see

kindred vector Dec 23, 2021, 9:50 PM

#

And when I look at that PaymentIntent, I see them

#

Other than cardHolderName those are all set on the PI from what I can see.

glad stag Dec 23, 2021, 9:51 PM

Terminal.getInstance().processPayment(collectedIntent, object : 
PaymentIntentCallback {
                            override fun onSuccess(@Nonnull confirmedIntent: PaymentIntent) {
                                val intentMap = Arguments.createMap()
                                var currency: String? = ""
                                Log.wtf("Reader payment success: ", "Success!!!");
                                if (options != null && options.hasKey(constants.CURRENCY)) {
                                    currency = options.getString(constants.CURRENCY)
                                }
                                intentMap.putMap(LiveFolders.INTENT, serializePaymentIntent(confirmedIntent, currency))
                                sendEvent(constants.EVENT_PAYMENT_CREATION, intentMap)
                            }

#

sorry for the formatting discord did - but yeah I pass the confirmedIntent which is a response after onSuccess

#

and it works on other cards

#

is there any other way I can query the payment intent id to get all that information

#

it looks like there is a way to retrieve the card from the customer Id and card Id but I can't find the card id when I make a request to get the information server side

kindred vector Dec 23, 2021, 9:59 PM

#

Going through line by line but it seems like all the fields that are related to the charge are null. Is it possible there was an issue looking up the charge?

#

Other than the id it seems

glad stag Dec 23, 2021, 10:00 PM

#

So I should mention that I found out that we don't actually capture the card for Interac because at processPayment it's an Interac thing to capture it on it's own

#

so maybe it's related to that

#

so with other cards I capture the payment server side

#

but that shouldn't really affect this response - unless if i'm missing to set anything important

Here's another response using the first example from above

karmic ridge Dec 23, 2021, 10:07 PM

#

catching up here, give me a min

glad stag Dec 23, 2021, 10:08 PM

#

sounds good!

#

okay it looks like I can send a request server side to fetch the payment intent information incase the response from the terminal comes back as null for the fields I need - because looking at paymentIntent.charges.data[0].payment_method_details.interac_present gives back this:

Payment intent:  {
  brand: 'visa',
  cardholder_name: null,
  country: 'CA',
  emv_auth_data: '8A0230308906313534313036910A497E6723CD6608228040',
  exp_month: 12,
  exp_year: 2023,
  fingerprint: 'pkfp6QLrjMexeCe8',
  funding: 'debit',
  generated_card: null,
  last4: '0326',
  network: 'interac',
  preferred_locales: [ 'en' ],
  read_method: 'contact_emv',
  receipt: {
    account_type: 'checking',
    application_cryptogram: '4C6E43C06A77F58A',
    application_preferred_name: 'Interac',
    authorization_code: '154106  ',
    authorization_response_code: '3030',
    cardholder_verification_method: 'offline_pin',
    dedicated_file_name: 'A0000002771010',
    terminal_verification_results: '8080008000',
    transaction_status_information: '7800'
  }
}

#

This is a little Node JS code I wrote to make this request:

 async function main() {
     try {
         const paymentIntent = await stripe.paymentIntents.retrieve('pi_3K9y5pFk5BSitd8b16xVTCwB');
         console.log('Payment intent: ', paymentIntent.charges.data[0].payment_method_details.interac_present);
     } catch (err) {
         console.log('ERR: ', err);
     }
 }

 main();

karmic ridge Dec 23, 2021, 10:36 PM

#

ok so mostly caught up I think, still missing a few pieces

mind resetting for me and starting from the top - you're looking at processPayment() and you get different fields set (or null) for a card_present PaymentIntent vs a interac_present PaymentIntent right?

mind sharing what those PaymentIntent IDs were for each where they were different?

There is a lot shared above so starting fresh so I don't look at the wrong things

glad stag Dec 23, 2021, 10:37 PM

#

yupp exactly

#

So this is the Interac present examples: pi_3K9y5pFk5BSitd8b16xVTCwB and pi_3K9y89Fk5BSitd8b0QomLEtC

karmic ridge Dec 23, 2021, 10:38 PM

#

and what is diff between the two?

glad stag Dec 23, 2021, 10:39 PM

#

And this is what I get with a card_present payment intent: {"amount": 206, "brand": "visa", "cardholderName": "SUNDERJI/ZISHAAN K", "chargeId": "ch_3K9zw4Fk5BSitd8b1gUibWKz", "clientSecret": "pi_3K9zw4Fk5BSitd8b1t70z8YT_secret_Of3VlXJjjrVR33JQzeNOI60N8", "country": "CA", "created": "2021-12-23T17:38:56GMT-05:00", "currency": "CAD", "customerId": null, "fingerprint": "2QJ5n3pC0Wp76Ypo", "funding": "credit", "generatedCardId": null, "lastFour": "2027", "readMethod": "contact_emv", "stripeId": "pi_3K9zw4Fk5BSitd8b1t70z8YT"}

#

There's basically no difference between those 2

karmic ridge Dec 23, 2021, 10:40 PM

#

is that your serialized output? ^above

glad stag Dec 23, 2021, 10:40 PM

#

Yuppp exactly

karmic ridge Dec 23, 2021, 10:40 PM

#

yeah lets ignore that for a bit

#

to isolate what the root issue is

glad stag Dec 23, 2021, 10:40 PM

#

gotcha

#

okay cool

#

so a transaction is going through successfully after processPayment and onSuccess I start serializing the payment intent I get back

karmic ridge Dec 23, 2021, 10:40 PM

#

let's look at the raw deserialized PaymentIntent objects we get back from processPayment() and work from there

(looking into the PaymentIntents you shared)

glad stag Dec 23, 2021, 10:40 PM

#

sounds good!

#

I'll log it!

karmic ridge Dec 23, 2021, 10:44 PM

#

ok so looked at both raw responses in the API and they do have all the fields that you saw null
e.g. brand , funding last4 etc are all present on the PaymentIntent's charge array's first Charge's payment_method_details hash

i.e. what you said here

paymentIntent.charges.data[0].payment_method_details.interac_present gives back this:

now ...

glad stag Dec 23, 2021, 10:45 PM

#

📎 message.txt

#

okay sorry that took sometime so this is a new transaction I did as a card present interac

#

and it's the raw payment intent that came back

#

and this is the serialized

{"amount": 206, "brand": null, "cardholderName": null, "chargeId": "ch_3KA019Fk5BSitd8b0Hermt6D", "clientSecret": "pi_3KA019Fk5BSitd8b0iBsOM3X_secret_utREGrzURPFArW2rfKVnVH7xI", "country": null, "created": "2021-12-23T17:44:11GMT-05:00", "currency": "CAD", "customerId": null, "fingerprint": null, "funding": null, "generatedCardId": null, "lastFour": null, "readMethod": null, "stripeId": "pi_3KA019Fk5BSitd8b0iBsOM3X"}

karmic ridge Dec 23, 2021, 10:47 PM

#

one sec, let's take it step by step

here is what I was writing:

#

from the SCPPaymentIntent you get back on processPayment , that should have a SCPCharge under the charges array
under which you have SCPPaymentMethodDetails
https://stripe.dev/stripe-terminal-ios/docs/Classes/SCPPaymentMethodDetails.html

which has interacPresent which is of type SCPCardPresentDetails and it should have all those fields that you want.

So assuming the SDK does its job right, the API response should get deserialized into those fields/objects correctly

#

now looking at the raw PaymentIntent object you got back one sec

#

ok so let's focus on this:

#

#923691612389904395 message

glad stag Dec 23, 2021, 10:48 PM

#

yuppp

karmic ridge Dec 23, 2021, 10:48 PM

#

that file is the entire SCPPaymentIntent object, and all its sub objects

#

that does have brand last4 funding etc all on it

#

so what I said here:

So assuming the SDK does its job right, the API response should get deserialized into those fields/objects correctly
that is happening correctly

glad stag Dec 23, 2021, 10:49 PM

#

oh it's under InteracPresentDetails

karmic ridge Dec 23, 2021, 10:49 PM

#

so Stripe's SDK gave you an object which has all the things you need

and your serialized object does not

#

so basically something in your serialization code is incorrect

glad stag Dec 23, 2021, 10:50 PM

#

cuz I think my serialized object is taking the value from cardPresentDetails not InteracPresentDetails

#

let me check

karmic ridge Dec 23, 2021, 10:50 PM

#

paymentMethodDetails has 2 sub objects: https://stripe.dev/stripe-terminal-ios/docs/Classes/SCPPaymentMethodDetails.html#/c:objc(cs)SCPPaymentMethodDetails(py)interacPresent

glad stag Dec 23, 2021, 10:50 PM

#

yupp

karmic ridge Dec 23, 2021, 10:50 PM

#

cardPresent vs interacPresent

glad stag Dec 23, 2021, 10:50 PM

#

gotcha - I didn't know that

#

makes a ton of sense

#

thanks a ton!! This was super helpful 🙂

karmic ridge Dec 23, 2021, 10:51 PM

#

you need to look at a different property in your code dependent on what the type is https://stripe.dev/stripe-terminal-ios/docs/Classes/SCPPaymentMethodDetails.html#/c:objc(cs)SCPPaymentMethodDetails(py)type

#

np! it is what we are here to do!

glad stag Dec 23, 2021, 10:51 PM

#

oh I see - sweet! There's a total of 4 kinds

#

perfect!!!

#

Thanks so much!!!

karmic ridge Dec 23, 2021, 10:51 PM

#

well really you'll only deal with 2 of them in Terminal

#

card_present and interac_present

glad stag Dec 23, 2021, 10:52 PM

#

yeah true!

#

Awesome!!

#

Thanks!!

karmic ridge Dec 23, 2021, 10:52 PM

glad to help!
