Stripe Checkout server-side load Customer cards - stripe-payments

In Stripe Checkout, using the server integration, is it possible to preload the customer saved cards?
I have a customer with a previous purchase history and I would like to let him pick a saved card details during checkout.
In the CRM I can see that cus_EyGeAZaPVHwUVg has the credit card stored (the test one for now, 4242...), but upon a new checkout I am not presented with that, even though the email is filled correctly.
I haven't seen any option in the docs, this is the code:
stripe.checkout.sessions.create({
payment_method_types: [paymentMethod],
line_items: [{
name: name,
description: description,
images: [imageUrl],
amount: amount,
currency: currency,
quantity: 1
}],
success_url: 'http://localhost:3000/success',
cancel_url: 'http://localhost:3000/cancel',
customer: 'cus_EyGeAZaPVHwUVg'
})

How can I create a Stripe checkout with custom amount to be paid?

When creating a checkout session, I am providing line items with price_data and quantity and in the checkout I see the correct amount. For some payments the customer can use their in-app points which will reduce some amount from the total checkout amount. How can I apply that to the checkout?
Example:
You buy 3 T-shirts (3x20) and one cap (1x15) which means you need to pay 75.00 (of some unit)
You use the in-app option to use your points which gives you 5.00, so now your checkout session must be a custom value (70.00).
I am using this API:
https://stripe.com/docs/api/checkout/sessions/create
The only solution that I came up with was to create a coupon right before creating the checkout and apply it to the checkout, but I don't know if that's safe.
Yes coupon should works with Checkout Session.
Maybe this will work.
var stripe = require("stripe")("YOUR_STRIPE_SECRET");
stripe.checkout.sessions.create(
{
payment_method_types: ["card"],
line_items: [
{
price: "YOUR_PRICE_ID",
quantity: 1,
},
],
success_url: "https://example.com/success?session_id={CHECKOUT_SESSION_ID}",
cancel_url: "https://example.com/cancel",
},
function(err, session) {
console.log(session.id);
}
);

Stripe Checkout session with total price and not unit_price

I'm working on a project currently. and I'm making use of stripe, the stripe.checkout.session.create function works perfectly.
const session = await stripe.checkout.sessions.create({
line_items: [
{
price_data: {
currency: "usd",
unit_amount: 500,
product_data: {
name: "name of the product",
},
},
quantity: 1,
},
],
mode: "payment",
success_url: "http://example.com/success",
cancel_url: "http://example.com/",
});
but the only issue i have is it receives only unit price.
but i want a field where i can pass only total Price, cause in my code , if the users applys a discount to a product , it deducts it from the product total price meanwhile the unit price for each product is stable.
My question is basically is there a field where i can pass total price.
Short answer is that you can't. You need to use the line_items parameter and either pass a Price object ID (price_xxx) or use ad-hoc pricing with the price_data parameter. Checkout will then compute the total from all line items, factoring in any discounts that you provide.
You have a couple of options to achieve the behaviour you want:
Re-calculate the price_data.unit_amount value to reflect the discount applied by your customers.
Utilise Stripe coupons to apply to the Checkout Session which will take care of the dedication for you.

Stripe Node - Calculating application fee AFTER discount coupon is used in checkout

I have a Stripe Checkout Session linked to a connected account. The connected account is subject to a 10% charge from my platform. It works well currently, however now I have added the ability for customers to use coupons in the checkout window, the application fee is being calculated from the total amount before the discount is applied.
For example, if I charge €32, the application fee is €3.20. If a discount reduces the charge to €10, the fee should be €1. But it is still charging €3.20.
I have a function which calculates the application fee amount, the problem is that this is done when the checkout session is created - this happens before the customer enters the discount.
I can't think of a way around this issue since the session is always created prior to the discount being applied. Any help/suggestions are appreciated!!
const calculateApplicationFeeAmount = (total) => total * site.stripeFee;
const session = await stripe.checkout.sessions.create(
{
payment_method_types: ["card"],
line_items: [
{
name: price.name,
amount: price.amount,
currency: site.currency,
quantity: 1,
},
],
payment_intent_data: {
application_fee_amount: calculateApplicationFeeAmount(price.amount),
description: price.name,
},
mode: "payment",
allow_promotion_codes: true,
success_url: `${config.baseUrl.url}/unlock/session/{CHECKOUT_SESSION_ID}`,
cancel_url: `${config.baseUrl.url}/unlock/${deviceID}`,
metadata: {
deviceID: deviceID,
},
},
{
stripeAccount: site.stripeAccount,
}
);
return session;
The best solution here would probably be to :
Use payment_intent_data.capture_method:manual when creating the checkout session
After receiving the checkout.session.completed event, update the application_fee_amount on the PaymentIntent
Capture the PaymentIntent
The limitation is that not all payment methods support manual capture.
Alternatively, you could also refund the application fee later : https://stripe.com/docs/api/fee_refunds/create

Stripe subscription webhooks missing metadata and client_reference_id

I'm having issues linking stripe webhooks to customers, since I generally use the client_reference_id or metadata field, however subscription webhooks seem to not have these fields. For example the event checkout.session.completed does contain the client_reference_id, whereas invoice.paid does not.
NodeJS code to generate payment:
const session = await stripe.checkout.sessions.create({
payment_method_types: ['card'],
line_items: [
{
price_data: {
currency: 'usd',
product_data: {
name: `Premium license`,
},
unit_amount: 600,
recurring: {
interval: "month",
interval_count: 1
},
},
quantity: 1
}],
subscription_data: {
trial_period_days: 1,
},
metadata: { 'userId': userId },
client_reference_id: userId,
mode: 'subscription',
customer_email: customerEmail,
success_url: `...`,
cancel_url: `...`,
});
Yes, it's a major missing that there is no option to link between events. This becomes critical when you can't rely on the order of webhook events.
I did work around this using metadata though. Pass your own reference id, say, my_database_reference_id to the metadata of both checkout.session.create and also in the subscription_data in checkout creation. This can be the same value you pass inside client_reference_id. Now you can use this while listening to webhook, to connect between the checkout session and subscription object, irrespective of the order it comes in.
NB: Please be warned that metadata can be edited by the Stripe Account, so please be careful if you are a platform and relying on this for any logic.
The client_reference_id is a property of Checkout Session objects in Stripe, but not any other Stripe objects.
Subscription events (like customer.subscription.created) describe Subscription objects, and Invoice events (like invoice.paid) describe Invoices, neither of which are Checkout Sessions, so the property is missing.
Typically the way all of this is linked together is with the Customer object (cus_123) in Stripe, which should be present on all of the events mentioned in the customer property. Checkout will create the Customer object for you if you don't specify an existing one.

Stripe default card in checkout

Is there a way to fill fields in a Stripe checkout page when customer comes back? I've tried to set default payment method for customer with webhooks (payment_method.attached) but this default credit card won't show up during checkout. Instead Stripe creates new payment method for the customer every time he pays. It's strange to have dozen of exactly the same credit cards in a Stripe dashboard. Here is my current code:
const checkout = await stripe.checkout.sessions.create({
cancel_url,
success_url,
payment_method_types: ["card"],
mode: "payment",
customer: stripeCustomer,
client_reference_id: stripeCustomer,
metadata: {
//...
},
line_items: [{
price_data: {
currency: 'usd',
product_data: {
name: packetDisplayName,
},
unit_amount: packetPrice,
},
quantity: 1
}]
})
I later use session id to redirect to checkout then perform few operations in a webhook endpoint
Thanks for taking the time to read my question, cheers
Checkout does not currently support using Payment Methods already attached to the provided Customer.
More broadly, there is not a concept "default" payment method for one-time payments for a customer, only for invoices.
If you already have a known Customer and an attached payment method, you also have the option of creating the payment yourself, directly, using those details.
try its work for me in Node.JS
For add card in node js
let card = await stripe.customers.createSource(customerid, {
source: token
});
Make card as default card
let updatecard = await stripe.customers.update(customerid, {
default_source: card.id
});
you can replace card.id if you just want update card only
