node.js - 使用不同的卡为现有客户创建费用

Question

所以我有一个客户已经创建了一张卡。
在前端，我提供了使用现有卡或其他卡的选项。
按照 API 文档，对于新卡，我创建 token ，将其发送到我的后端...

在后端:

const paymentInfo = {
  customer: customerId,
  amount: Number(total) * 100,
  currency: 'usd',
  source: existingCardId || token
}

const charge = await stripe.charges.create(paymentInfo)

如果我使用现有卡付款，则费用会通过，但如果我发送新 token ，则会收到错误消息:

Customer cus_G4V0KvxKMmln01 does not have a linked source with ID tok_1FYMLTAOg97eusNI2drudzlJ.

来自 API 文档: https://stripe.com/docs/api/charges/create

source optional A payment source to be charged. This can be the ID of a card (i.e., credit or debit card), a bank account, a source, a token, or a connected account. For certain sources—namely, cards, bank accounts, and attached sources—you must also pass the ID of the associated customer.

Answer 1

我找到了解决方案:

if (token) {
  const card = await stripe.customers.createSource(customerId, {
    source: token
  })
  paymentInfo.source = card.id
}
