Create a hosted subscription management session
POST/subscription-management/sessions
Validates ownership of the active base subscription and the allowlisted application return URL, then returns a short-lived signed launch URL. The session is a stateless browser capability and does not create a durable command or remote-operation record. Provider webhooks and reconciliation remain authoritative for the effective subscription.

Short-lived service-hosted management launch URL
Bad Request
Unauthorized
Forbidden (realm/account mismatch, billing account not derived from your session/principal, or insufficient role)
Not Found
Conflict (idempotency body mismatch, duplicate adjustment, or an unsupported provider capability). Unsupported mutations return BILLING.PAYMENT_PROVIDER_CAPABILITY_UNSUPPORTED before Customer creation, provider I/O, or local state mutation. Concurrent use of the same Idempotency-Key returns WRITE.IDEMPOTENCY_IN_PROGRESS; different keys are independent requests whose final ordering is owned by the PSP. A subscription Checkout with mixed group, currency, or recurrence facts is rejected before Customer lookup or provider I/O. Missing or inconsistent selected Customer bindings return BILLING.PAYMENT_PROVIDER_CUSTOMER_REQUIRED or BILLING.PAYMENT_PROVIDER_CUSTOMER_CONFLICT without silently replacing the binding.
Unprocessable Entity (validation, visibility, or binding/meter unresolved)
