or you have to use the customer id

#

Hello 👋
Could you provide me more information on the use-case here?

marsh temple Mar 31, 2022, 2:37 PM

#

on the backend i have ephemeral key for ios

#

i was wondering if i could use that for web as well setting up a setup intent

#

and if not and there is no customer id for the setup intent is there some other mapping i can use so when the response comes asynchronously i can do the mapping on the backend

#

sorry not used to discord not sure if i’m doing this right

raw crescent Mar 31, 2022, 2:47 PM

#

Let me look into it.
Just juggling between a few threads at the moment

marsh temple Mar 31, 2022, 2:48 PM

#

ok thanks is this the right place to ask ? and this private thread to discuss?

raw crescent Mar 31, 2022, 2:48 PM

#

Yup this is the right place

#

Thank you for your patience.
We don't recommend that you use Ephemeral keys for web as they're designed to work with mobile SDKs.

#

AFAIK In order to create an Ephemeral key, you'd need a customer right?

marsh temple Mar 31, 2022, 3:03 PM

#

yes the backend has the customer

raw crescent Mar 31, 2022, 3:04 PM

#

f not and there is no customer id for the setup intent is there some other mapping i can use so when the response comes asynchronously i can do the mapping on the backend
I'm not sure what you mean by this. Can you give me an example?

marsh temple Mar 31, 2022, 3:04 PM

#

well on the web site the user will add a payment with setup intent right ?

#

but according to the video associated with that you can skip the customer id

#

and attach the customer to the payment instrument later

#

so without giving the web app the customer id

#

how can i map the asynchronous response back to the customer

#

https://stripe.com/docs/payments/save-and-reuse

Set up future payments

Learn how to save card details and charge your customers later.

#

the webhook for the asynchronous response is on the back end, not the web app

#

i just want to mimic the mobile device flow, the mobile device never sees the customer id

#

i want to maintain the customer id on the back end without sharing it with the web app

#

does that suffice as an example?

raw crescent Mar 31, 2022, 3:25 PM

#

I don't know if stripe.js supports ephemeral keys though

marsh temple Mar 31, 2022, 3:27 PM

#

well im not asking for ephemeral key specifically, is there ANY way to map the payment intent to customerid on the back end?

raw crescent Mar 31, 2022, 3:37 PM

#

Okay wait
Let's take a step back here as your original ask mentioned ephemeral keys.

If I understand it correctly, (feel free to correct me at any point)

You want to create a SetupIntent (server-side)
Confirm it (client-side)
Associate it with a customer (server-side)

marsh temple Mar 31, 2022, 3:37 PM

#

change the first step to client-side without a customer id and you have it

raw crescent Mar 31, 2022, 3:40 PM

#

Ah okay. Thanks for clarifying.
What are you planning on using on the client-side? Stripe checkout, Stripe.js ?

marsh temple Mar 31, 2022, 3:40 PM

#

stripe checkout

raw crescent Mar 31, 2022, 3:41 PM

#

Pre-built checkout page correct?

marsh temple Mar 31, 2022, 3:42 PM

#

i think it redirects to stripe.com

#

to capture the user's payment details

raw crescent Mar 31, 2022, 3:43 PM

#

gotcha. let me quickly check something.

marsh temple Mar 31, 2022, 3:43 PM

#

thank you

loud raptor Mar 31, 2022, 4:12 PM

#

catching up here one sec @marsh temple

#

mind summing up your question in one line, if possible?

marsh temple Mar 31, 2022, 4:12 PM

#

sorry?

#

using stripe checkout on the client side, is there anything i can use instead of the customer id to map the payment intent on the back end to the customer id when the asynchronous webhook is called

loud raptor Mar 31, 2022, 4:15 PM

#

nope, you just use the Customer ID of the Customer that completed the CheckoutSession

marsh temple Mar 31, 2022, 4:42 PM

#

would metadata work?

loud raptor Mar 31, 2022, 5:11 PM

#

that can work too
