Create a refund for a deposit. Only deposit movements with operation_type = CREDIT are eligible.
A refund may still fail after being initially marked as SUCCESS; in such cases, you'll receive a callback with status = FAILED.
To simulate a failed refund in the sandbox, create a deposit with amount = 101 (see the Create Deposit endpoint for details).
To refund a Payin, use the Create Refund endpoint from Payins.
