invoice_not_payable

HTTP status: 409 Conflict. Retrying the same request unchanged fails the same way.

Why it happens

• Its payments are already worth its amount.
• It was voided: its subscription ended, dunning ended, or a plan change issued it again.

What to do

Pay the subscription's latest open invoice instead (latest_invoice on the subscription).

Example

The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
