Loyalty points that are converted into reward certificates have an expiration date. Members can cancel their rewards if they are unable to use them before expiration or do not want to use them. The endpoint converts the rewards back into points, for future use.
Note: Once the reward is redeemed, it cannot be cancelled. If the member cancels or returns an order, the rewards are reversed back to points using the
Reverse Redeemed Reward endpoint - POST v1/redeem/reverse.
