Hello! Yes, that's possible.

[sharp schooner]

how would i go about doing this?

[hollow peak]

There are several ways. Can you tell me more about how your Stripe integration works?

At a high level you need to set up Payment Methods for future use so you can charge them with Payment Intents later.

[sharp schooner]

ooo thats interesting

so i am using flutterflow (flutter) with a fastapi backend

its a bit janky

[hollow peak]

We don't officially support Flutter, so you might want to ask the folks who built flutterflow for help.

[sharp schooner]

so in order to do this i would need to create a stripe express account and have the user add a card

[hollow peak]

I'm not sure how an Express account would be involved?

[sharp schooner]

i have just been building it in python then using api to get it across

how would i store the card details?

to automatically charge the card

[hollow peak]

There are, again, several ways. You can use a Setup Intent. You can use a Payment Intent with setup_future_usage. You can use Checkout, etc.

[sharp schooner]

this is interesting, however the only issue that that i dont know how much the amount is till after

so a booking is made, payment for the booking is taken. after the booking is complete i want to be able to charge them any extras

[hallow thicket]

👋 hopping in here since rubeus has to head out

If you don't know the amount ahead of time then SetupIntents are what you want - they don't require any amount to save the payment method

[sharp schooner]

np

and it just allows me to in theory charge anything to that payment method

with out their permission

[hallow thicket]

It gives you the ability to attempt to charge that payment method later while the cusotmer isn't on-session

It's always possible that for cards the bank/card network will still want to collect authentication again, but that should be exception, not the norm

[sharp schooner]

ok

so i am currently using an integration that does an inital payment here

pi_3NpHPzDzTJHYWfEw1VhKo5LW

for example

could i use the information from this payment intent to create a setup intent

[hallow thicket]

What do you mean by "use the information from this payment intent"?

[sharp schooner]

so with the stripe customer connected to this payment intent

or the payment method on this payment intent

can i create a setupIntent

i.e

my current integration with stripe, creates the pi i have given you. using python. can i from the pi. create a setupIntent

[hallow thicket]

The payment intent is unrelated here

All you'd need to do is create a Setup Intent w/ the Payment Method you want to setup

[sharp schooner]

could i do

pi = stripe.PaymentIntent.retrieve(
  "pi_3NpHPzDzTJHYWfEw1VhKo5LW",
)

stripe.SetupIntent.create(
  "payment_method":pi.payment_method,
  "usage":off_session,
)

something like this?

[hallow thicket]

Yes, for this specific case it would work

but is this something you're planning on building into your app?

[sharp schooner]

somthing along these lines

however i then need to have the user confim it?

[hallow thicket]

If this is something you're actually intending to build into your app, then instead of creating a separate Setup Intent AND a Payment Intent, you should just create the Payment Intent w/ setup_future_usage: off_session

I suggested creating a SetupIntent for that specific payment intent you shared because it's already been created, but moving forward you should just change your integration to use setup_future_usage with payment intetns to make it easier

[sharp schooner]

ok, great. just one more area

the confirmation

how does that work

in your case

of adding it to the first payment intent

[hallow thicket]

You mean when using setup_future_usage?

[sharp schooner]

yes

i assume that is an optional attribute on a pi?

ahh it is

then yes

[hallow thicket]

Yup it's somethign you'd set when you create the PI

[sharp schooner]

amazing

you have been amazing, thank you!
