Refund payment

The amount of money the developer contributes to help cover the refunded amount. This amount is specified in the smallest denomination of the applicable currency (for example, US dollar amounts are specified in cents).

The value cannot be more than the amount_money.

You can specify this parameter in a refund request only if the same parameter was also included when taking the payment. This is part of the application fee scenario the API supports. For more information, see Take Payments and Collect Fees.

To set this field, PAYMENTS_WRITE_ADDITIONAL_RECIPIENTS OAuth permission is required. For more information, see Permissions.

Additional details required when recording an unlinked cash refund (destination_id is CASH).

The Customer ID of the customer associated with the refund. This is required if the destination_id refers to a card on file created using the Cards API. Only allowed when unlinked=true.

The ID indicating where funds will be refunded to. Required for unlinked refunds. For more information, see Process an Unlinked Refund.

For refunds linked to Square payments, destination_id is usually omitted; in this case, funds will be returned to the original payment source. The field may be specified in order to request a cross-method refund to a gift card. For more information, see Cross-method refunds to gift cards.

Additional details required when recording an unlinked external refund (destination_id is EXTERNAL).

The location ID associated with the unlinked refund. Required for requests specifying unlinked=true. Otherwise, if included when unlinked=false, will throw an error.

The unique ID of the payment being refunded. Required when unlinked=false, otherwise must not be set.

Used for optimistic concurrency. This opaque token identifies the current Payment version that the caller expects. If the server has a different version of the Payment, the update fails and a response with a VERSION_MISMATCH error is returned. If the versions match, or the field is not provided, the refund proceeds as normal.

A description of the reason for the refund.

An optional TeamMember ID to associate with this refund.

Indicates that the refund is not linked to a Square payment. If set to true, destination_id and location_id must be supplied while payment_id must not be provided.
