Apply a change from hosted subscription management
POST/subscription-management/change
Applies the existing provider-neutral subscription change service. The signed session supplies ownership context and Idempotency-Key supplies stable mutation identity. Provider facts still converge through webhook processing and reconciliation.

Provider mutation accepted, scheduled, or committed
Bad Request
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.
Management session expired
Unprocessable Entity (validation, visibility, or binding/meter unresolved)

Internal Server Error
Provider unavailable, transient failure, or an ambiguous provider mutation reported as BILLING.PAYMENT_PROVIDER_OUTCOME_UNKNOWN.
