Void or refund payin

The billing rate and fee to calculate the merchant's billing fee for the amount of the refund. If set, then this rate and fee will be used to determine the billing fee for the refund and will override the merchant's billing profile.

This is only applicable if the payin results in a refund instead of a void.

Negative values for the rate and fee can be utilized to return billing fees to the merchant (e.g. to give the fees from the payin back to the merchant upon refund).

Represents how the refund amount should be allocated between the originating merchant, the platform, and one or more other merchants. This configuration overrides the amount_split_reversal_config defined on the payin config.

The sum of all amount splits must be less than or equal to the amount on the refund request.

A PLATFORM split defines the amount to debit from the platform. A maximum of one PLATFORM split is permitted per refund.

A MERCHANT split defines the amount to debit from the specified merchant. Multiple MERCHANT splits are permitted. Each MERCHANT split must specify a unique merchant_id.

Any remaining amount not specified by the amount splits will be debited from the originating merchant.

If no amount splits are provided, then the configuration provided on the payin config amount_split_reversal_config will be respected for full refunds. For partial refunds without amount_splits, the originating merchant will be debited the full partial refund amount and all split receivers retain their allocations.

The amount split is defined as a rate and amount.

For example, to assess a split of 1% + $5.00, specify 1000 in the rate and 500 in the amount.

Controls whether the billing fees from the original payin are returned to the originating merchant. This configuration overrides the billing_fees_reversal_config defined on the payin config or the merchant's default configuration.
