Instant payouts have a fallback mechanism: when the payout cannot be processed as an instant payout, a standard one will be processed instead. This is what occurred when you encounter the 130008 error code.
When more than one payout is made to the same bank account for the same amount in less than 24 hours, the instant payment request is processed as a standard payout. Information about the error is returned in the FallbackReason parameter.
