#

sorry i'm back

#

it just doesn't seem to work

minor flame Sep 23, 2021, 8:25 PM

#

Haha never be sorry

#

Can you remind me how you are creating this PaymentMethod?

green thorn Sep 23, 2021, 8:27 PM

#

I'm using the "create a subscription through elements" method, and I'm just trying to retrieve the payment method Id from the payment intent

minor flame Sep 23, 2021, 8:27 PM

#

Do you have the id of a payment method you want to get the card for?

green thorn Sep 23, 2021, 8:28 PM

#

yeah, it's a card_xxxx thing right

minor flame Sep 23, 2021, 8:31 PM

#

I was thinking the pm_123 for the payment method

green thorn Sep 23, 2021, 8:31 PM

#

what i'm doing is basically

get the customer object using the customer's id
get the customer's customer.invoice_settings.default_payment_method_id
get the payment intent of the invoice
get the payment method id of the payment intent
if the two payment_method_ids don't match, then update the customer's with the new payment_method_id

#

am I mistaking payment method for payment_method? I'm starting to feel like they're not the same thing

minor flame Sep 23, 2021, 8:34 PM

#

Sorry for being imprecise

#

But yes in this case I meant them to be the same thing

#

Can you give me the value of a customer.invoice_settings.default_payment_method_id that you want to retrieve the original card object for?

#

And ah this is so you can check the fingerprint right?

green thorn Sep 23, 2021, 8:36 PM

#

minor flame And ah this is so you can check the `fingerprint` right?

exactly (and update to new card if it doesn't match)

green thorn Sep 23, 2021, 8:36 PM

#

minor flame Can you give me the value of a `customer.invoice_settings.default_payment_method...

that's the hard part. It always return null.

#

No matter how i try to set it through the dashboard, it's always null.

minor flame Sep 23, 2021, 8:37 PM

#

I don't think it is settable in the dashboard

#

I think when we talked about the Dashboard before we noticed that that set the default_source correct?

green thorn Sep 23, 2021, 8:38 PM

#

yeah.

#

Does this mean this is testable only when our frontend is also done?

minor flame Sep 23, 2021, 8:39 PM

#

Not necessarily, you can set that field with the API now.

green thorn Sep 23, 2021, 8:40 PM

#

which is what we're doing here -- using the API to get, and set that property if it doens't match

#

It's not a problem if initially the value is null, since a new customer will always have a null value to that

#

so the next question is the payment_intent's payment_method is also null for some reason

#

if you want the PaymentIntent Id

#

here's a snippet of what i got from the PaymentIntent (thru CLI). This also indicates that the payment_method of the intent is not set, but instead the source is set.

minor flame Sep 23, 2021, 8:54 PM

#

Right, so that is just what the Dashboard does, unfortunately we can't set the invoice_settings.default_payment_method_id property there.

#

If you use the CLI/API to set it otherwise I think that will fill out the field that you want

#

I know we discussed setting it and doing this check in webhooks before but you can do it outside of that for your testing right?

green thorn Sep 23, 2021, 8:56 PM

#

i've only implemented

set it after receiving webhook -- didn't work
get the customer's payment_method through code -- didn't work

green thorn Sep 23, 2021, 9:00 PM

#

minor flame Right, so that is just what the Dashboard does, unfortunately we can't set the `...

I understand, but that's not the problem here. I am using Stripe.NET to do this = through API.
The chain of problems are:

The problem here is I cannot get the PaymentIntent's payment_method
due to (1) , i cannot set the customer's invoice_settings.default_payment_method to a value.
due to (2), I cannot get the customer's invoice_settings.default_payment_method (it will always be null).

#

--
On a second thought, maybe it is because the dashboard only allows me to set to the source of a customer, which would lead me to the series of problems

#

It was never going to work in the first place

minor flame Sep 23, 2021, 9:01 PM

#

And you were talking about setting this in the invoice.paid event right?

green thorn Sep 23, 2021, 9:01 PM

#

yep

minor flame Sep 23, 2021, 9:01 PM

#

You can still use what the Dashboard does I believe

green thorn Sep 23, 2021, 9:03 PM

#

but the subscription is paid using an order of sources. If the dashboard will only set any card to the source instead of payment_method, then i'm never going to get anything from payment_method

minor flame Sep 23, 2021, 9:04 PM

#

The Dashboard still creates a PaymentMethod when you input one. It doesn't get set in that one setting but it will show up if you list the customer's PaymentMethods https://stripe.com/docs/api/payment_methods/list

#

So you are only ever setting this via Dashboard? I thought you were taking in payment info initially when setting up the subscriptions correct?

green thorn Sep 23, 2021, 9:05 PM

#

yeah. but i'm testing that's why

#

we don't have our front-end ready yet

minor flame Sep 23, 2021, 9:05 PM

#

You can create a test PaymentMethod directly in the API and attach the resulting object to your customer https://stripe.com/docs/api/payment_methods/create

green thorn Sep 23, 2021, 9:06 PM

#

but is that how purchasing a subscription will behave?

I can totally use the list to implement the default payment method feature. Just do aggressive housekeeping and keep the list to one element. But that defeats the purpose of having a default_payment_method in the first place

minor flame Sep 23, 2021, 9:11 PM

#

I mean to initially set this

#

Can you remind me how you are setting up these subscriptions?

green thorn Sep 23, 2021, 9:12 PM

#

I'm just following https://stripe.com/docs/billing/subscriptions/elements

#

When listening to invoice.paid event, I check whether the billing_reason is subscription_create or manual.
if it's either one of the two, then I also take the PaymentIntent ID to fetch the payment_method.
I take this payment_method and do fingerprint comparison with that of the customer's. The rest you know already

minor flame Sep 23, 2021, 9:19 PM

#

Okay I see. Apologies I see where you specified this and I missed it

#

So when you get to the step where it wants you to look at invoice_paid or invoice_succeeded and you check that Invoice's PaymentIntent's PaymentMethod, is that null?

green thorn Sep 23, 2021, 9:21 PM

#

yep

minor flame Sep 23, 2021, 9:23 PM

#

Interesting. And you are passing the card and billing_details in to the payment_method parameter of your confirmCardPayment call>?

green thorn Sep 23, 2021, 9:25 PM

#

That is a no, because I am currently only testing it through the dashboard, so it didn't go that way.

minor flame Sep 23, 2021, 9:27 PM

#

Right. You've said that. Caught up.

#

So a quick way to create a subscription that would look like what you will get from the frontend would be use the backend API to create a customer, a PaymentMethod, and then create a Subscription
https://stripe.com/docs/api/customers/create
https://stripe.com/docs/api/paymentmethods/create
https://stripe.com/docs/api/subscriptions/create

green thorn Sep 23, 2021, 9:34 PM

#

creating a customer that's solved

#

do you mean by i need to explicitly call to create a payment method first, then create the subscription afterwards?

minor flame Sep 23, 2021, 9:35 PM

#

I mean in this test case yes

#

So because you don't have the frontend you will need to do some other API noodling to get a Subscription set up and paid for similarly

#

Which actually needs one last bit of detail:

#

Actually do you know what might be even easier?

#

We have a sample with elements for creating a subscription, before your frontend is ready you can just use this and swap it out to your subscription plan ids and such https://github.com/stripe-samples/subscription-use-cases/tree/master/fixed-price-subscriptions

#

OR

#

You can use checkout to create a subscription https://stripe.com/docs/billing/subscriptions/checkout

#

Apologies for taking a bit to get there.

green thorn Sep 23, 2021, 9:41 PM

#

cool, i'll take a look at these

#

well, we're aiming to use elements -- more customizable
