SetItemsAwaitingPaymentPreferencesType

autoRelist

This boolean field is included if the seller wishes to toggle the setting that controls whether or not the line item should be automatically relisted when cancelled. For this field to be set to true, the optInStatus field should also be true.
Note: If the line item was part of an auction listing or a single-quantity fixed price listing, a new listing will actually be created. If the line item was part of a multiple-quantity fixed price listing, eBay will only adjust the quantity based on the cancelled line item’s quantity.

delayBeforeCancellingCommitment

This integer field is included if the seller wishes to set or change the number of business days without payment that must elapse before the line item is cancelled. This is a required field if the optInStatus field is true.
Note: The supported integer values (representing business days) varies by eBay marketplace.

excludedUsers

array of string

This array is used if the seller wishes to exclude one or more eBay users from the unpaid item assistance mechanism. The seller would need to manually cancel any unpaid line items for all users on this list. This array will not be returned if there are no users on the excluded users list.
Note: The eBay public username is used for each excluded user, and a comma is used to delimit each user in the array.

optInStatus

This boolean field is included if the seller wishes to toggle the setting that controls whether or not the seller is opted into the unpaid item assistance mechanism. If the seller is not opted in, no other fields under itemsAwaitingPaymentPreferences are applicable.

removeAllExcludedUsers

This boolean field is included and set to true if the seller wishes to remove all eBay users from the current excluded users list. If this field is included and set to true, the excludedUsers array should not be included.
