Hello 👋
We have a guide here that explains how you can use it with Checkout, Payment Links, Subscriptions etc
https://stripe.com/docs/products-prices/getting-started#use-products-and-prices

late bison Sep 12, 2022, 3:39 PM

#

well

#

I dont need a subscriptuon

#

and payment links... not sure what they are.. but they sound like not what U need

#

what I need

#

so what is checkout?

#

is that the buy once thingy?

compact perch Sep 12, 2022, 3:40 PM

#

Checkout offers stripe hosted payment page where customers can put in their information and pay
https://stripe.com/docs/payments/checkout

late bison Sep 12, 2022, 3:40 PM

#

, hosted on Stripe.

#

no

#

I want this hosted in our app

#

so in our app, I want to button - e.g. buy a one hour consultation

#

then I want the customer to confirm the payment with 3D secure, using their alreadt existing credit card

#

(default card)

compact perch Sep 12, 2022, 3:43 PM

#

Then you can create invoices for the prices
https://stripe.com/docs/invoicing/integration#create-invoice-code

late bison Sep 12, 2022, 3:45 PM

#

I dont follow

#

you mean, by creating an invoice, the customer technically buys / pays it?

compact perch Sep 12, 2022, 3:47 PM

#

yup

#

PaymentIntents don't take in price objects as a parameter

late bison Sep 12, 2022, 3:49 PM

#

but this api asks for the invoice id..

#

thats weird... as I am just creating it

compact perch Sep 12, 2022, 3:49 PM

#

so if you do want to utilize the price object then your options are as mentioned here
https://stripe.com/docs/products-prices/getting-started#use-products-and-prices

If you don't want to use the price object then you can use the custom payment flow
https://stripe.com/docs/payments/accept-a-payment
https://stripe.com/docs/payments/save-and-reuse?platform=web#charge-saved-payment-method

#

but this api asks for the invoice id..
thats weird... as I am just creating it
Not sure I follow

late bison Sep 12, 2022, 3:51 PM

#

no I want the price object

#

I was just asking that it asks me to put an invoice id also

#

anyway I wrote now:

#

.builder()
.setCustomer(stripeCustomerId)
.setCollectionMethod(InvoiceCreateParams.CollectionMethod.CHARGE_AUTOMATICALLY)
.setDaysUntilDue(0L)
.build();

#

--
would that mean - charge - NOW

#

and how to add 3Dsecure to that.. I assume with a payment intent?

#

.addExpand("latest_invoice.payment_intent")
.build();

            Invoice invoice = Invoice.create(params);
                   
                    String clientSecret = invoice
                        .getPaymentIntentObject()
                        .getClientSecret();

#

myabe like that?

#

????
hello world?

tame sorrel Sep 12, 2022, 4:08 PM

#

Ah, sorry for the delay! I'm catching up on your question since my colleague had to step away

#

Taking a step back here to make sure I understand the question

#

You want to add a payment flow to your website to allow customers to complete a one-time purchase. Do you want to charge them immediately, or just store their payment details and create a charge at a later time?

late bison Sep 12, 2022, 4:14 PM

#

the payment details were stored earlier

#

for a subscription

#

now they want to buy a cherry on the cake 😉

#

so I guess ideally, they would charged just in time when clicking the BUY NOW button

#

with their already existing default card

#

but 3d secure.. so I assume I need to send back a payment intent secret to the frontend?

#

or would hte frontend initiate all of this and the backend would JUST create a payment intent secret for confirmation?

tame sorrel Sep 12, 2022, 4:16 PM

#

Ah I see

late bison Sep 12, 2022, 4:19 PM

#

and?

tame sorrel Sep 12, 2022, 4:20 PM

#

I think you can handle this a few ways. You can add a one-time item to the subscription, which will be included in their next invoice: https://support.stripe.com/questions/how-to-add-one-time-items-to-invoices-and-subscriptions-in-the-dashboard

#

https://stripe.com/docs/api/subscriptions/update#update_subscription-add_invoice_items

#

You can create a separate invoice and use the previously-saved payment payment method (from the subscription) and charge them immediately

late bison Sep 12, 2022, 4:21 PM

#

what if there is no next invoice becasue they would cancel earlier.. then this could be a problem, I assume

#

You can create a separate invoice and use the previously-saved payment payment method (from the subscription) and charge them immediately

#

I assumer thats what I did above

#

still my question, how to create the payment intent, which, as I assume, I would need... can I create it as an extension in the same call?

tame sorrel Sep 12, 2022, 4:27 PM

#

You can create the PaymentIntent server side, using the customer's existing payment_method

late bison Sep 12, 2022, 4:28 PM

#

the question is how to combine the request for minimal number of requests.

#

https://stripe.com/docs/invoicing/integration/quickstart

Create and send an invoice

Learn how to create and send an invoice with code.

#

based on this, I have now created that:

#

public void oneTimePayment(String stripeCustomerId, String stripePriceId) {
try {
InvoiceCreateParams params = InvoiceCreateParams.builder()
.setCustomer(stripeCustomerId)
.setCollectionMethod(InvoiceCreateParams.CollectionMethod.CHARGE_AUTOMATICALLY)
.setDaysUntilDue(0L)
.addExpand("latest_invoice.payment_intent")
.build();

        Invoice invoice = Invoice.create(params, requestOptions);

        InvoiceItemCreateParams invoiceItemParams = InvoiceItemCreateParams.builder()
            .setCustomer(stripeCustomerId)
            .setPrice(stripePriceId)
            .setInvoice(invoice.getId())
            .build();

        InvoiceItem.create(invoiceItemParams, requestOptions);

        InvoiceSendInvoiceParams invoiceSendInvoiceParams = InvoiceSendInvoiceParams.builder()
            .build();
        invoice.sendInvoice(invoiceSendInvoiceParams, requestOptions);
    } catch (StripeException e) {
        throw new StripeExternalException(e);
    }

#

so it seems, for the whole thing I do not need 1, but actually 3 requests already

#

now where of these 3 requests can I add my
.addExpand("latest_invoice.payment_intent")
so that I retrieve the secret for the client / frontend payment 3dSecure confirmtion?

#

And the order - is it actually - backend creates the invoice and the secret, or should the client / frontend create the invoice and then the backend only create the secret.. ?? I assume the first, as only the backend would have the right stripe price id in its database

fossil summit Sep 12, 2022, 4:38 PM

#

reading up and answering, one sec

#

if you're /send sending the Invoice, why would you want the client_secret on the frontend? Sending Invoices means the Invoice is emailed to the end Customer so they can pay from their email inbox (just clarifying that part)

#

and answering each of your questions:

#

so it seems, for the whole thing I do not need 1, but actually 3 requests already

yes this is expected, you're
a// creating an Invoice
b/ adding an InvoiceItem to the Invoice
c/ sending the Invoice

these are 3 distinct requests, you can't batch them up in 1

#

now where of these 3 requests can I add my
.addExpand("latest_invoice.payment_intent")

You don't add that expand

You just do

 .addExpand("payment_intent")

You don't need the latest_invoice part there

#

and you add it to

a// creating an Invoice
or
c/ sending the Invoice

#

is it actually - backend creates the invoice and the secret, or should the client / frontend create the invoice and then the backend only create the secret.. ??

Backend creates the Invoice
Invoice has an underlying PaymentIntent on it automatically
Frontend only calls confirmPayment() on the PaymentIntent's client_secret

but you don't need to do the last thing necessarily since you are emailing the Invoice to the end customer

THanks

#

this is super helpful

#

waitinf for hour here, you are the first one to fully and properly answering my questions, thank you!
