Let me explain more

I have created customer with user sign up and saved customer id

now i have to give user option to save their payment method

as per docs i have to setup intent and then pass the client secret to credit card form.

how can I use stripe built in page in nextjs for this? so that at end i directly get the payment token that I can use to charge user at month end for their subscription amount

[sturdy horizon]

My first advice would be to use Stripe Checkout. It's a pre-built payment form and it does everything for you. It collects card details, email address and can start a Subscription automatically for you
Since you are quite lost, this is likely the best approach for you. See https://stripe.com/docs/payments/checkout and https://docs.stripe.com/subscriptions/quickstart

[sullen hazel]

no the cart amount will change everytime so subscritions can't be used

i read the checkout docs
but how do I use it in nextjs?

[sturdy horizon]

Subscriptions can totally be used even if the "cart amount" changes every time. Though that sentence can mean many different things so I'll need you to be a lot more specific about your business model and what you need help with.

As for Next.js we don't really have any specific docs for that framework sorry. You'll have to map our examples to your own code

ohh

so basically user saves their payment method, then add items to cart
and checkout

now when the delivery happens, the payment gets deducted automatically from user account 7 days before the delivery

can I use subscription in this?

[sturdy horizon]

Sorry this is still really cryptic. Is this a recurring payment situation? Or just one-time payment and done?

[sullen hazel]

basically the business is about eco foods
so we provide boxes with organic foods

Once the User creates an account, they are presented with their box (which is empty at the beggining) and a huge array of various items. The User then goes through those items and adds the ones they like to their box. Once they have added their wanted products, they click a button to activate the box. This is where they have to enter all their payment details. Once all of the payment info has been saved, the box will be activated, and the User will receive their goods, which they have selected, every 30 days from the box activation date. The User can change the content of their box anytime, they just need to deactivate the box, remove/add items, activate the box back again. If the box is not active the user will not be charged. If they deactivate their box within 2 weeks left until delivery, they will still be charged for that delivery.

so we are saving payment method so that they don't have to manually pay every month

so tl;dr
its subscription based, but amount can change as per box value

@hard flame can you confirm you are taking over?

[hard flame]

I'm taking over now. Thanks for the ping

So yeah, Subscriptions would work for this use-case. Have you already created a test flow for this? There's a great quickstart guide here for using Checkout to get the Subscription setup: https://docs.stripe.com/billing/subscriptions/build-subscriptions

In terms of updating the Subscription each month, you would need to use a different flow other than Checkout, since Checkout only creates the Subscription. It doesn't allow for updating it. For updating the Subscription, you would want to look into the Customer Billing Portal to get started: https://docs.stripe.com/no-code/customer-portal

[sullen hazel]

ok let me try setting up subscription

but to change
i want the code solution only
or stripe hosted solution that gives me output in callback

is it possible?

can you tell me one more thing
https://docs.stripe.com/payments/save-and-reuse?platform=web&ui=stripe-hosted#create-checkout-session

in this part it says to pass session_id
do I have to create a random string or fetch it from somewhere?
CHECKOUT_SESSION_ID

[hard flame]

Let's focus on one question at a time.

The Billing Portal I linked to will require that you use webhooks to get notified of updates the Customer makes during the Portal Session. If you don't want to do that, then you would have to build a custom front-end that allows the customer to update the their Subscription, which would fetch() your server and make back-end API calls to Stripe.

[sullen hazel]

oh this won't work for us then the subscription thing

i will use this saving for future payments only then

[sullen hazel]

can you tell me this?
