hello! that is not supported, I know the team has heard that feedback but no timeline on if/when that would be supported

sacred sequoia Apr 12, 2022, 10:14 PM

#

can payment elements support the charges api with a token?

craggy nova Apr 12, 2022, 10:14 PM

#

it does not! only supports PaymentIntents and PaymentMethods

#

I think you're trying to do server-side payments right?

#

what is the use-case

sacred sequoia Apr 12, 2022, 10:14 PM

#

yep

#

its a little bit of a long one

#

I'm doing event ticketing

#

I've designed a system that works using the charges api that:

gets the user information + the amount of tickets they want
puts a hold on that money in their account
sets them as the owner of the tickets
transfers the money to a connect account
4b. If the transfer fails then they lose ownership of the tickets

#

For this to work I need to be able to not confirm the payout immediately, I need to set the payment Intent amount on my backend after they checkout, and I need to be able to work on my backend so I can manage ticket ownership

I've taken care of the first two of these by using a setup intent to start

#

but now I need to get a token i can use for a payment intent on my backend to finish the process

you're using a SetupIntent with a PaymentMethod, so that PaymentMethod is what you want to use to confirm a PaymentIntent server-side

#

the "token" is the PaymentMethod

sacred sequoia Apr 12, 2022, 10:21 PM

#

would stripe?.createPaymentMethod(elements) work?

#

where elements is bound to the PaymentElement

#

?

craggy nova Apr 12, 2022, 10:22 PM

#

but why do createPaymentMethod()

like don't you already have a PaymentMethod because of

I've taken care of the first two of these by using a setup intent to start

like your SetupIntent is collecting a PaymentMethod, no?

sacred sequoia Apr 12, 2022, 10:23 PM

#

so i can just send the client secret back to my backend?

#

I think im starting to get this better

#

would I use confirmSetup?

craggy nova Apr 12, 2022, 10:37 PM

#

let's take a step back

#

can you detail to me, exactly what you've implemented here:

I've taken care of the first two of these by using a setup intent to start

#

what are you doing with a SetupIntent?

sacred sequoia Apr 12, 2022, 11:17 PM

#

I think I'm actually really getting it now

#

Can setupIntent redirects have form payloads?

hollow sleet Apr 12, 2022, 11:22 PM

#

Hmm, this is not supported.

sacred sequoia Apr 12, 2022, 11:23 PM

#

how do i handle if a client secret has already been used, but then a user goes back?

hollow sleet Apr 12, 2022, 11:32 PM

#

If the Setup is not used, then the client secret is not used. They can go back and use that client serret as it has not been consumed.

sacred sequoia Apr 12, 2022, 11:37 PM

#

to get the redirect I have to use stripe.confirmSetup

#

and once i do that, when a user goes back to the page, the page doesn't work anymore because it says the setup intent has already been used

hollow sleet Apr 12, 2022, 11:45 PM

#

In this case, you won't be able to use the client secret as this is already consumed and you'd have a payment method.

#

What are you trying to achieve here?

sacred sequoia Apr 12, 2022, 11:48 PM

#

currently dealing with stripe.confirmSetup({}), which redirects them to a page that takes in the data and completes the purchase

#

which works

#

however, if a user then presses the back button, and tries to buy more tickets, then it doesn't work

hollow sleet Apr 12, 2022, 11:54 PM

#

In this case, if you expect a purchase, you'd want to use the Payment Intents: https://stripe.com/docs/payments/payment-intents and https://stripe.com/docs/api/payment_intents

sacred sequoia Apr 12, 2022, 11:58 PM

#

i explained earlier in this conversation why i can't use a payment intent

#

i don't know the price ahead of time

scarlet wasp Apr 13, 2022, 12:03 AM

#

So what's blocking you with SetupIntents?

sacred sequoia Apr 13, 2022, 12:04 AM

#

that if a user:

enters their card
clicks purchase
we do stripe.confirmSetup with redirectMode always
they get redirected, but then press the back button
they enter their card again,

scarlet wasp Apr 13, 2022, 12:05 AM

#

When they press the back button they just reload the page right? So you should know who they are and that they did a SetupIntent already and you would redirect them back to another page

sacred sequoia Apr 13, 2022, 12:05 AM

#

then 5 won't work because it throws a "setup_intent_unexpected_state"

sacred sequoia Apr 13, 2022, 12:06 AM

#

scarlet wasp When they press the back button they just reload the page right? So you should k...

it doesn't always reload

#

browsers cache back by default

scarlet wasp Apr 13, 2022, 12:06 AM

#

Gotcha, so in that case you catch the error and you can handle this accordingly by showing them that they are already confirmed.

sacred sequoia Apr 13, 2022, 12:07 AM

#

alright

#

thank you

#

wait

#

can I reuse the same secret twice?

#

if they choose to purchase tickets for a second time

scarlet wasp Apr 13, 2022, 12:08 AM

#

No, the secret is associated to that SetupIntent and it's completed at that point.

#

But you also don't need another SetupIntent if you already have their card details

sacred sequoia Apr 13, 2022, 12:09 AM

#

so i can reuse the payment method on the setup intent?

scarlet wasp Apr 13, 2022, 12:09 AM

#

what do you mean "reuse the payment method on the setup intent"

sacred sequoia Apr 13, 2022, 12:10 AM

#

there is an id of a payment_method on the setup intent

#

can i reuse it more than once?
