A transaction is eligible for a refund only after it has been successfully paid. Multiple partial refunds are allowed, but the total refunded amount must not exceed the original transaction amount. For multiple partial refunds, only one refund request for the same transaction may be in progress at any given time; the next refund can only be initiated after the current one has been completed.
