Customer portal API

These routes accept a customer-session bearer token—not a seller API key. Every resource is limited to the signed-in customer and redacted for customer use. Read subscription capabilities immediately before showing an action.

A subscription's trial_ends_at is only set while it is TRIALING, so it is the date to show the customer as their trial end. The seller API's trial_ends_at keeps its value after the trial. A plan change preview says in preview.payment_required whether confirming charges amount_due today, and in preview.renewal_date when the subscription renews next.

A Stripe, PayPal, or Razorpay subscription with a payment still owed can only be cancelled immediately, or, on Razorpay, have its payment method updated too; every other action reads unsupported. A subscription the store bills in house that is on hold for an unpaid renewal comes back only when the customer pays that renewal on the store's own customer portal page, so resume reads unsupported here and the resume route returns 422. See Failed payments.
