如何为付款意图创建结帐 session？

Question

I'm using stripe to create an payment integration in my system, after creating an payment intent i want to create checkout session for this payment, after this i want to retrieve an url property from this checkout and send to the user.

But i don't have an idea how to "connect" created payment intent to checkout session.

Right now i create payment intent in this way:

    const paymentIntent = await stripe.paymentIntents.create(
      {
        amount: 500,
        currency: "usd",
        customer: customerId
      },
      {
        stripeAccount: ""
      }
    );

and checkout session:

    const session = await stripe.checkout.sessions.create({
      success_url: "",
      cancel_url: "",
      mode: "payment",
      customer: customerId,
      payment_method_types: ["card"]
    });

The problem is in this, that i don't know how to create checkout session based on created before an payment intent.

Thanks for any help!

Answer 1

The Checkout Session itself will create a PaymentIntent. You can create an equivalent PaymentIntent with the line_items.price_data.unit_amount [1], line_items.price_data.currency [2], and customer [3] parameters of the checkout.sessions.create call. Make sure to pass in the stripeAccount parameter to your Session creation call as well if you want to create the Session/PaymentIntent on their account.
