Validate Payout Parameters
Validate payout parameters and destination before processing a payout request.
This endpoint is currently supported for the UNIONPAY and BANK_TRANSFER methods, and is intended to ensure that the payout request meets the necessary minimum criteria for successful processing. Note that even a pre-validated payout may still fail to be processed if the destination is invalid for other reasons not checked by this endpoint.
