payment-gateway - 订阅取消后，Stripe API退款

Question

从Stripe文档中:

When you cancel the subscription, the customer's card will not be charged again, but no money will be refunded either. If you'd like to issue a refund, you can do so through Stripe's dashboard or via the API.

我创建了每月订阅，我只想退还订阅月份内尚未过去的天数。在Stripe API尚未完成的日子里，如何只退还订阅中的金额？

Answer 1

Stripe现在将处理此问题。它可以立即取消订阅并创建发票，将月内未使用的费用退还给他们。

https://stripe.com/docs/api/subscriptions/cancel

添加“比例”标签以退还剩余的每月费用。

在PHP中:

$subscription = \Stripe\Subscription::retrieve(
  'SUBSCRIPTION_ID'
);

$subscription->delete([
    'prorate' => true
]);

编辑:

@Dobes Vandermeer在下面评论并指出了我的错误。上述方法实际上不会按比例退还客户款项，而只会创建一个帐户信用，该信用将应用于下一张发票。

以下代码实际上会将按比例分配的金额退还给卡。如果客户将其订购数量切换为零，它将生成按比例分配的发票示例。然后，它会从其有效订阅的最后一张发票中按比例退还该金额。

“subscription_proration_date”标记是可选的，但对于需要从特定时间点按比例分配订阅的情况很有用。

// get active subscription
$subscription = \Stripe\Subscription::retrieve(' SUBSCRIPTION_ID ');

// sample prorated invoice for a subscription with quantity of 0
$sample_subscription_item = array(
    "id"       => $subscription->items->data[0]->id,
    "plan"     => $subscription->items->data[0]->plan->id,
    "quantity" => 0,
);

$upcoming_prorated_invoice = \Stripe\Invoice::upcoming([
    "customer"                    => $subscription->customer,
    "subscription"                => $subscription->id,
    "subscription_items"          => array($sample_subscription_item),
    "subscription_proration_date" => ' PRORATED_DATE ', // optional
]);

// find prorated amount
$prorated_amount = 0;
foreach($upcoming_prorated_invoice->lines->data as $invoice) {
    if ($invoice->type == "invoiceitem") {

        $prorated_amount = ($invoice->amount < 0) ? abs($invoice->amount) : 0;

        break;

    }
}

// find charge id on the active subscription's last invoice
$latest_invoice = \Stripe\Invoice::retrieve($subscription->latest_invoice);
$latest_charge_id = $latest_invoice->charge;

// refund amount from last invoice charge
if ($prorated_amount > 0) {

    $refund = \Stripe\Refund::create([
        'charge' => $latest_charge_id,
        'amount' => $prorated_amount,
    ]);

}

// delete subscription
$subscription->delete();
