@spice maple what's the charge for though? Is it for a subscription? or a single time payment?

#

well, in any case, it's possible for both, you would simply need to implement the necessary logic

spice maple Sep 28, 2021, 8:24 AM

#

it's for subscriptions

#

In our case we have a "premium until" date on our system

#

This date is updated every time a card is successfully charged

#

the problem is that updating the customers card is not sufficient

#

we also need to immediately retry the failed charge

#

otherwise they will still be locked out of their account

modest cargo Sep 28, 2021, 8:25 AM

#

ah that's fine, so for a subscription, there's also an underlying invoice and payment intent, so you would just need to charge the card for the underlying payment intent of that particular unpaid invoice

spice maple Sep 28, 2021, 8:26 AM

#

yes, that's what we want to do. and if the charge fails, they remain locked out of their account.

modest cargo Sep 28, 2021, 8:26 AM

#

one point i'd want to highlight is that you would want to remember to set invoice_settings.default_payment_method [0] after collecting the new card details

[0] https://stripe.com/docs/api/customers/update#update_customer-invoice_settings-default_payment_method

spice maple Sep 28, 2021, 8:26 AM

#

i've done that bit

#

i've managed to change the default payment method

modest cargo Sep 28, 2021, 8:27 AM

#

sounds like you're all good to go then

spice maple Sep 28, 2021, 8:27 AM

#

not really because the failed charge doesn't get re-tried immediately

modest cargo Sep 28, 2021, 8:27 AM

#

you need to manually charge it

spice maple Sep 28, 2021, 8:27 AM

#

so we need to expedite that failed charge

#

can you point me in the right direction for the api documentation

modest cargo Sep 28, 2021, 8:29 AM

#

probably this bit : https://stripe.com/docs/api/payment_intents/confirm

spice maple Sep 28, 2021, 8:33 AM

#

ok i'll give it a go

#

thanks

modest cargo Sep 28, 2021, 8:33 AM

#

feel free to reach out again if you're having trouble 😄

spice maple Sep 28, 2021, 8:34 AM

#

👍

#

hey

#

this situation is quite hard to test

#

is there any way to simulate a failed charge?

#

also..

#

what about the case where a customer simply wants to change their card

#

and there are no outstanding charges

modest cargo Sep 28, 2021, 8:48 AM

#

use this test card : 4000000000000341 -> Attaching this card to a Customer object succeeds, but attempts to charge the customer fail.

#

so attach the card to a customer, then create a new subscription on the customer

spice maple Sep 28, 2021, 8:49 AM

#

payment intent confirmation.. how does it work? if there are outstanding charges, it will attempt to retry them, but if there are no outstanding charges, it will simply return success?

modest cargo Sep 28, 2021, 8:49 AM

#

@spice maple then you would simply add the card to the customer using a setup intent : https://stripe.com/docs/payments/save-and-reuse

spice maple Sep 28, 2021, 8:50 AM

#

we want to use the same flow for changing cards .. whether this is initiated by a customer or is the result of a failed charge

modest cargo Sep 28, 2021, 8:50 AM

#

the only additional step, is whether or not you run the confirm payment intent request

spice maple Sep 28, 2021, 8:50 AM

#

right

modest cargo Sep 28, 2021, 8:51 AM

#

you're going to need to add the logic to determine if there is a outstanding payment

spice maple Sep 28, 2021, 8:51 AM

#

so i would have to detect outstanding payments and then run paymentintent confirm, or does paymentintent confirm perform this check itself?

#

ah

#

jinx

#

ok

#

can you point me in the right direction for the api call to detect outstanding payments

modest cargo Sep 28, 2021, 8:54 AM

#

@spice maple sorry, i'm going to need to step away for a bit, someone else will be following up on your question here. Just give them a while to catch up on things!

winged tendon Sep 28, 2021, 8:56 AM

#

@spice maple hello, I will take over. Let me catch up

spice maple Sep 28, 2021, 8:57 AM

#

orakaro, thanks

winged tendon Sep 28, 2021, 9:02 AM

#

Hello @spice maple , I am not following the "outstanding payments". What are you referring as an outstanding payment?

spice maple Sep 28, 2021, 9:02 AM

#

when a card declines a payment

#

because it cannot be charged

#

a rejected payment

winged tendon Sep 28, 2021, 9:03 AM

#

okie

#

So you want to know how to detect a rejected payment?

spice maple Sep 28, 2021, 9:05 AM

#

yes

#

and then retry it immediately

winged tendon Sep 28, 2021, 9:05 AM

#

How are you creating a PaymentIntent? Isn't the result of that API call telling you the authorization result?

spice maple Sep 28, 2021, 9:07 AM

#

first, the customer sets up a subscription using stripe checkout

#

but weeks or months later

#

the card might reject the payment

#

due to insufficient funds or whatever

#

and if this happens

#

we lock them out of the app

#

until they update their payment method

#

but updating the payment method does not trigger a new attempt on failed charges

leaden tartan Sep 28, 2021, 9:08 AM

#

indeed it does not

spice maple Sep 28, 2021, 9:08 AM

#

so we need to trigger a new attempt on failed charges

#

before we allow them access to the app again

leaden tartan Sep 28, 2021, 9:08 AM

#

then you call the same API you use to charge the card, just again, it's all code you write

spice maple Sep 28, 2021, 9:09 AM

#

we are not charging the card right now

#

it's all being done by stripe automatically

leaden tartan Sep 28, 2021, 9:09 AM

#

so you use Subscriptions?

spice maple Sep 28, 2021, 9:09 AM

#

yes

leaden tartan Sep 28, 2021, 9:09 AM

#

then you call invoice.pay

#

https://stripe.com/docs/api/invoices/pay

spice maple Sep 28, 2021, 9:09 AM

#

will that tell us whether the payment was successful?

#

will that only charge where there are outstanding failed charges?

#

or will it charge in all cases?

leaden tartan Sep 28, 2021, 9:10 AM

#

it will charge the invoice you tell us to charge

spice maple Sep 28, 2021, 9:10 AM

#

ok

#

so i need to find the failed charge invoice

#

how would I do that?

leaden tartan Sep 28, 2021, 9:11 AM

#

you need to keep track of what subscriptions and invoice payments failed

#

for example you could use https://stripe.com/docs/api/invoices/list#list_invoices-subscription to get the recent invoices for a given customer

#

and then you retry them

spice maple Sep 28, 2021, 9:12 AM

#

so I can pull a list of invoices and filter it by failed charges

#

then re-attempt the failed ones?

leaden tartan Sep 28, 2021, 9:13 AM

#

yes

spice maple Sep 28, 2021, 9:15 AM

#

ok thanks

#

i will give it a go

spice maple Sep 28, 2021, 9:30 AM

#

on the list of invoices

#

is there an easy way to tell if the payment failed?

#

#

i can look at "amount_due" and "amount_paid"

#

and see the discrepancy

#

but is there another property?

winged tendon Sep 28, 2021, 9:32 AM

#

Invoice should have "status"

spice maple Sep 28, 2021, 9:34 AM

#

yes, status "open"

#

also "paid" -> false

#

thanks

#

what about the reason for payment failure?

leaden tartan Sep 28, 2021, 9:35 AM

#

that's part of the charge object
