Use this endpoint to redeem a cart_discount_voucher reward, which will apply a fixed or percentage discount to the whole cart. If the redemption is successful, the new claimed reward and a unique voucher (coupon) code will be included in the response.

You can show the voucher code to the customer and instruct them to apply it to their cart later. Or, if supported by your ecommerce platform, you can apply the voucher code to the cart directly, which provides a superior user experience.

Note that cart discount vouchers can have a minimum spend, found in claimed_reward.redeemable.minimum_spend. If present, this should be communicated to the customer to avoid confusion.
