IssueRefundResponse

The value in this field indicates whether or not the refund operation was successful. If the PENDING value is returned, it may indicate that the refund is happening outside of eBay's system and there is no way for eBay to check the status of the refund. In this scenario, the seller should call POST /post-order/v2/return/{returnId}/mark_refund_sent to mark the refund as sent and/or the buyer should call POST /post-order/v2/return/{returnId}/mark_refund_received to mark the refund as received.
