【问题描述】：

我正在为我的 SAAS 应用使用 Stripe 支付网关。

我创建了一个产品，并且多个计划链接到它。计划价格以美元为单位。

我创建了一个新客户。然后我尝试订阅计划，但出现以下错误

You cannot combine currencies on a single customer. This customer has had a subscription, coupon, or invoice item with currency inr

我看过他们的文档，它不允许我更改客户的货币。

在订阅之前我可以将美元兑换成客户的货币吗？

【参考方案1】：

我的建议是，在附加订阅之前，检索您希望为其附加订阅的客户对象，确定客户的货币，并在必要时创建一个新计划（以货币计） .但要做到这一点，您可能需要使用第三方的货币转换 API，因为 Stripe 不支持。

Python 示例：

plan_id = ...  # This would have been retrieved from your form, most likely  (eg. 'basic-plan')

usd_plan = stripe.Plan.retrieve(plan_id)

cus = stripe.Customer.retrieve()

if cus.currency is not 'usd':  # if the currency of the customer is not "usd"

  # create a new plan id for currency (eg. 'basic-plan-cad')
  plan_id = plan_id + '-' + cus.currency  # check if there is a 

  # use a 3rd party to get the currency
  amount_in_currency = amount * <API_CONVERSION_RATE>

  # check that the plan doesn't already exist and create it otherwise
  try:
    stripe.Plan.create(
      amount=amount_in_currency,
      interval=usd_plan.interval,
      product=
        "name": usd_plan.product
      ,
      currency=cus.currency,
      id=plan_id
    )
  except Exception as e:  # this may fail if the plan already exists
    break

# create the subscription
sub = stripe.Subscription.create(
  customer="cus_xxx",
  items=[
    
      "plan": plan_id,  # this will either be the `basic-plan` or `basic-plan-currency
    ,
  ]
)
