Stripe: invoices.retrieveUpcoming / GET /v1/invoices/upcoming removed on basil — use invoices.createPreview

stripe-api@2025-03-31.basilstripe@18#stripe#invoices#billing#api-version
Fix
- const upcoming = await stripe.invoices.retrieveUpcoming({ customer, subscription })
+ const preview = await stripe.invoices.createPreview({ customer, subscription })

Proration preview for a plan change:

await stripe.invoices.createPreview({
  customer, subscription,
  subscription_details: { items: [{ id: itemId, price: newPriceId }], proration_behavior: "create_prorations" },
})

Symptom

Code that previews the next invoice or a proration (stripe.invoices.retrieveUpcoming({ customer }), GET /v1/invoices/upcoming, /v1/invoices/upcoming/lines) no longer exists in the SDK types or fails on the new API version.

Cause

2025-03-31.basil removed the Upcoming Invoice API in favor of the Create Preview Invoice API. You also can no longer preview a customer's next invoice across all their subscriptions. You must pass something specific along with customer: subscription, subscription_details.items, schedule, schedule_details.phases, or invoice_items.

Verify

The preview returns an Invoice object with no id persisted. grep -rn retrieveUpcoming should be empty.
