Do we just create new prices every time we send a stripe checkout for this product_id?

You can use price_data to set dynamic amount, and it can still refer to the same product ID: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-line_items-price_data-product

so do i create a price with the product or no?

[cerulean basin]

You only need to pre-create a product. Price can be set every time a Checkout Session is created.

One question: do you have the amount at the time when you create a Checkout Session? Or you only want to collect payment information?

[turbid cairn]

yes

we have the amounts

they set it prior to creating the custom checkout

so we can set dynamically for every checkout i guess

thank you!

Yes, then you can create the the Checkout session with custom amount, like this:

const session = await stripe.checkout.sessions.create({
  ...
  line_items: [
    {
        price_data: {
           currency: 'usd',
           product: 'prod_xxx', // your existing product ID
           unit_amount: 9900, // custom estimated amount for this session
        }
        quantity: 1
     },
  ],
  mode: 'payment',
});
