Free products can only be refunded on Shopify, and must use Shopify Functions. If you are still using Shopify Scripts for free products, get in touch and we’ll switch you over to Shopify Functions
Use this endpoint to manually refund a free product reward. This will refund the points used back to the customer, and invalidate the associated free product line discount. This can be used when you detect a shopper has removed a free product reward from their cart. Note that if you refund a free product reward that is still in the cart, it won’t be removed automatically, and will not be discounted at checkout. To prevent confusion for shoppers, you should always ensure that refunded free product rewards are also removed from the cart.

​
Interaction with the Initialize Customer Session API

If you are initializing a customer session regularly (e.g. on each page load, or after any change to the cart), and you are passing your current serialized cart, you typically do not need to manually refund free product rewards. The Initialize Customer Session API will use your serialized cart to check if any active free product rewards are present in the cart. If any are missing, they will be automatically refunded.
