Currently we have below incentives-api :
Description: Using CancelGiftCard endpoint, we can cancel a gift card, as long as the gift card is not claimed by an Amazon customer. The original creationRequestId used for creating the gift card will be necessary to cancel a gift card.
But we can only cancel gift card within 15 minutes of the creation request time stamp. Once the time period has elapsed, the claim code cannot be cancelled.
So is there any other way or incentives-api to return gcClaimCode back to Amazon and get refund to user.
