not_refundable

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

Why it happens

• Only a finished payment, or a partially paid one that has closed, can be refunded.
• Its refunds, finished and under way, already add up to what it credited.

What to do

Retrieve the payment: amount_credited, amount_refunded and refund_pending show what remains. List its refunds with GET /v1/refunds?payment=….

Example

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