Hello 👋
looking into it

ember moat Mar 1, 2022, 9:15 PM

#

We had thought about just over-authing an arbitrary amount above the customer's order's cost, in case of upcharges, but that doesn't seem like a best practice

#

Yup that's one way to go about it. An alternative is to cancel the previous authorization and create a new one with a bigger amount.

#

I also noticed payment intents could have multiple charges, is it possible to add a charge to a payment intent after capture?

#

And per the two options you mentioned, would the second be considered "best practice" for this kind of situation?

I'm not sure about this of the top of my head. I'd suggest trying it out in test mode

And per the two options you mentioned, would the second be considered "best practice" for this kind of situation?
Yup it is

#

I'd also recommend reaching out to our support team on this to see if there are any beta APIs available that can simplify your flow

#

In order to create a new bigger amount payment intent, would I need to save the charge method info between cancel and creation?

#

We are using Stripe Terminal, which would make this harder to implement

#

as wedo not want to save customer info on kiosk

#

Ah I see. Looking

#

Yeah I don't see another way to create a new auth without storing the payment method in some way

#

There's a Beta API for incremental authorizations
https://stripe.com/docs/terminal/features/incremental-authorizations
You can write in and see if you're eligible

#

It will allow you to increase the authorized amount on a confirmed PaymentIntent before you capture it

#

The other option would be attaching the generated_card to your customer and creating a new payment intent / auth from that for a larger amount.

iron nova The other option would be attaching the `generated_card` to your `customer` and...
