Use this endpoint to redeem a collection_discount_voucher
reward, which will
apply a fixed or percentage discount to line items that belong to the designated
collection. 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.
Details of the collection to which this voucher applies can be found in
claimed_reward.redeemable.collection
, and this should be shown
to the customer.
Note that collection 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.
